“The Origin of Ogg Vorbis” Part 2

By the way, there is an item called “stream serial number” in the header. Ogg can handle multiple data streams and OggStream on the Xiph.Org website As shown in the figure at the bottom of the explain page, you can compose a file by mixing three streams of red, light blue, and green.

In this case, it will be shuffled page by page, so it is necessary to indicate “what flow data I have” on each page. This is indicated by the serial number of the sequence.

■ Vorbis characteristics

Vorbis, on the other hand, comes from the name of the main character in Terry Pratchett’s novel “Small Gods.” Basically, it has very similar characteristics to MP3s. Specifically, it has the following characteristics, and it is a “slightly better than MP3” number.

-Uses MDCT (Modified Discrete Cosine Transform)
-The sampling rate is 8 KHz to 192 KHz
-Precision
sampling is 16/24

bits -Maximum number of channels is 255 channels Bit rate is not uniquely determined as described below. The goal is to ensure a quality that beats MP3 at the same bit rate compared to the average bit rate, and the quality is generally said to be roughly the same as AAC.

On the other hand, there are some differences. The most important point is that the bit rate is only “VBR (Variable Bit Rate)”. MP3 uses “CBR (constant bit rate)”, so in summary, the playing time and the file size are in a proportional relationship.

In Vorbis, on the other hand, both timbre and play time are related to file size, and as a result, the file size is roughly the same as MP3 for the more complicated timbre and smaller for the more complicated timbre. simple. it is one of the factors for better sound quality than MP3 if it has the same bit rate. However, on the other hand, the fact that the processing required to encode / decode is definitely more than MP3 is a disadvantage of Vorbis.

■ The future of Ogg Vorbis

Ogg Vorbis is implemented on multiple platforms and, in addition to Windows / Mac OS / UNIX / LINUX, OS / 2 and Pocket PC players are available as standard. However, the official source is limited to providing the necessary libraries (and a simple interface).

In addition to this, for example, plugins for Windows Media Player and media players like WinAMP support it as standard, and groundwork is being prepared. However, the following factors can be considered as the reasons why it has not been widely used. -Is not

much better than MP3-There is no
a lot of support in portable players

Especially for the second point, the following problems are likely to exist.

-Since both encoding and decoding have a higher load than MP3, processing with a portable player is a bit heavy, and as a result there are disadvantages such as a reduction in continuous playback time.
-It does not have a copyright protection feature (this is from Xiph.org) as it is not set as a policy), it is unlikely to be used for music distribution which is popular these days,

and although it is not recognized that it is necessary to back it up with a portable player, there are cases in which music is distributed with Ogg Vorbis little by little, I am beginning to see it and I think that little by little it will increase its power in the future. However, to become a major format, you need some kind of opportunity, but it is a bit disappointing that such a move seems not to be that particular so far.

The Origin of Ogg Vorbis

“The Origin of Ogg Vorbis”

■ What is Ogg Vorbis?

“Ogg Vorbis” is another audio format similar to the term used so far. Strictly speaking, Ogg and Vorbis are separate, Ogg refers to a container, a container for storing audio data, and Vorbis is the audio codec method.

You can think of it as the same as storing videos from video codecs like CinePak, Indeo, WMV, and DivX in a video format called AVI. However, Ogg itself is not as popular as AVI.

So far, Ogg supports “FLAC – Lossless Audio Codec”, “Speex – Specialized Audio Codec for Conversation Recording”, “Theora – Free Video Codec”, “Icecast – Streaming Audio”. Of these, is FLAC the only one that is relatively widely known during the period? For this reason, there is a section where Ogg and Vorbis are generally recognized as the same thing, and the facts support it.

■ Establishment of Ogg Vorbis

Ogg Vorbis, the container named Ogg and the Vorbis codec, was created by Xiph.Org. This is a non-profit organization whose purpose is to provide multimedia technology that anyone can use freely. Ogg Vorbis is a typical example of this, and it can be used for free even for commercial use, with no royalties or license fees, only with the following conditions.

-Specifications: Public Domain (that is, it can be modified in addition to free, there are no restrictions)
Software: The utility provided by Xiph.Org is GNU GPL (There are no restrictions on use, but there is an obligation to publish the source). Also, most libraries / SDKs have a modified BSD license (the copyright notation of Xiph.org author is not removed when distributing or modifying). From

So, PC games made in Japan often use Ogg Vorbis. However, one of the reasons is said to be that there are no royalties. Behind this movement is the fact that the popular MP3 format license is actually loaded. MP3 encoded music data is exempt from the license fee depending on certain conditions, but basically it is charged. Thomson of France obtained a patent and obtained it under license. The specific license fee is the one shown here, which has hindered the spread of free encoders / decoders.

Even in Japan, “It’s afternoon” temporarily stopped distribution (click here for details on this process) .Xiph.Org has started work to create a free format that is not subject to patents, etc., so to counteract these movements. The development work started in 1993 and the distribution of Ogg Vorbis already started in 2000 (although the version is recent).

Since then, FLAC has joined Xiph.Org (which was previously developed into its own project), and Speex and Theora have joined. Checking the current version, Icecast is 0.8.6 and Theoa is 1.0 Alpha 7 (both as of Dec 2006), which is a bit recent, but all other libraries are over 1.0 so it can be used stably by the moment. I can see that it is.

■ Ogg Features

First, let’s look at Ogg’s features. Ogg was adopted by RFC in May 2003 as “RFC3533 (The Ogg Version 0 Encapsulation Format)” and “RFC3534 (The Application Media Type / ogg)”. By the way, the name Ogg has been popular as a “strategy (tactic?) Of attacking a special attack (Kamikaze Attack) with the Orion G ship (commonly known as Og)”, and this is converted to counter the enemy’s strategy. which is called Ogg. It seems to have been converted. In this case, it seems to have the meaning of counteracting the strategy of the major licensees to earn revenue through patent licensing.

Ogg’s structure is surprisingly easy. First, the original bitstream is divided into 255-byte “packets”. This 255 bytes is the maximum value, so it can be 254 bytes or less. Then put this package on a “page”. Each page has a 27-byte header, for a maximum total page length of 282 bytes. The Ogg file is built by grouping several pages together.

The page header at the top of each page has the structure shown in Table 1. This header is interesting. For example, even if you rearrange the order after dividing it by page, you can still see the header and revert to the original order. It’s more like looking at the Ethernet or IP headers rather than the file format.

What is an Ogg (Ogg Vorbis) file?

What is an Ogg (Ogg Vorbis) file?

Ogg Vorbis

The Ogg file (Ogg Vorbis) is a kind of audio file, and it seems to be called Ogg or Odge. It mainly has the following characteristics.

Ogg vorbis

The file size can be reduced compared to uncompressed audio files.
The sound before compression cannot be fully reproduced. (Lossy compression)
It is often used for PC games due to its flexible license restrictions.
Supports gapless playback

MP3 difference
Ogg can play better than MP3s at the same bit rate, and it appears to be comparable to other lossy compression formats like AAC and WMA. Its performance is highly rated, especially at low bit rates.

Also, when distributing MP3-compatible software or hardware, you have to pay a license fee, while Ogg does not have to pay a license fee. So it seems like it is often used when handling compressed audio in PC games as described above.

Other lossy compression formats
Lossy compression formats other than Ogg Vorbis include:

MP3 (MPEG 1 Audio Layer 3)
AAC (advanced audio coding)
WMA (Windows Media Audio)
ATRAC (TRansform Adaptive Acoustic Coding)
Compared to these, it appears that there are still few Ogg-compatible portable music players due to popularity and technical factors.

Playing Ogg files with Windows Media Player [Tutorial]

An Ogg file (Ogg Vorbis) is a type of lossy compressed audio file, similar to MP3 and AAC. It is being used recently as it has few license restrictions. However, it is not currently supported as standard on Windows and Mac.

So this time I will show you how to play Ogg files with Windows Media Player.

It should be noted that the characteristics of Ogg files and Ogg files (Ogg Vorbis) refer to. Also, if you want to handle Ogg files with iTunes, please play Ogg files with iTunes, and if you want to edit Ogg files, “You can edit Ogg files with SoundEngine!

Mp3 vs OGG digital audio format (OGG VORBIS)

OGG digital audio format (OGG VORBIS)

MP3 vs Ogg Vorbis Compression - Visual Comparison - YouTube

This digital audio format, like MP3, also uses lossy compression.

The OGG format is based on a psychoacoustic model, but the mathematical processing is fundamentally different from MP3.

The OGG format has the main advantage: with the same bit rate, this format offers superior quality!
It is the OGG digital audio format that is popular and is second only to MP3 in prevalence. This format is compatible with all computer programs for playing sound files and all operating systems.

But unlike MP3, it has less support at the hardware level.
Not all stereos, audio players, and DVD players support this format.

Considering the advantages of the OGG digital audio format, it is promising. And it’s the future in the digital audio format market. The development of recent years shows that the OGG digital format is becoming more and more popular.

OGG digital audio format (OGG VORBIS)
By the way, in the comments to the article on the MP3 digital audio format, most wrote that as a better alternative, you need to use this compressed digital format.

The advantages of this digital format:
1. More modern: it was presented to the public in 2002.

2. This format is the most MODERN among the competitors of the MP3 format.

3. It has a series of innovations, such as:

– Advanced and better quality psychoacoustic model and mathematical compression model;
– High quality sound reproduction with the same bit rate as MP3;
– Supports multi-channel audio;
– can handle up to 255 different channels.
– variable bit rate encoding is possible, which makes the compression algorithm more flexible;
– a wider range of bit rates and sample frequencies available for compression (2 to 192 kHz);
– the ability to adjust audio compression more flexibly, achieving the necessary balance, just for you, between recording quality and file size;
– has the most flexible tag management system among all competitors – textual explanations for the audio file, including: the name of the song, the album it is included in, the author, the year of release and much more useful information (it has practically no length limit and can be in different languages).
The MP3 implementation only allows 2 channels (stereo sound) to work.
Considering the fact that modern sound devices have long crossed the threshold of the two channels (for example, the 5.1 format, which uses five speakers and a subwoofer), this difference is very important for consumers and listeners , especially in modern movies and computer games.

Ogg vorbis

Today, the term Mp3 is in the public domain. Everyone knows what it is, or at least everyone knows that it is something you hear. In fact, the MPEG-1 Layer III compression standard allows you to download the content of about ten albums onto one CD, while maintaining good sound quality. This is possible thanks to a compression algorithm that treats frequencies according to the psychoacoustic perception model, eliminating all those sounds of frequencies above 15,000 Hz, the maximum threshold that man can perceive.

It is a very poor description, but it should serve only as a theoretical starting point: Mp3 to be considered as a mode of operation that allows to fully exploit the spaces that were previously full of inaudible frequencies.

We must bear in mind, however, that there is not only this format. Sure it is the most renowned, but the choice is quite wide: Mp3 pro, Mpeg-2 AAC … The characteristics change from one case to another, but the only one that in my short experience in the field caught my attention was the Egg Vorbis. This new encoding format (already in common use under the name ogg files) launched by Xiph.org, has achieved the not inconsiderable goal of being counted as RC3, that is, the initial debugging phase has been passed and will soon be will become an official standard in the encoding of audio sources. But what does it get its name from? Ogg is nothing more than the name of the audio and video encoding and metadata format published by Xiph.org, while Vorbis is the specific name given to the encoding scheme developed to be contained in the Ogg suite. Instead, the logo derives from Norse mythology: it portrays Thor as he prepares to “compress” the serpent Jörmungandr with his trusty hammer Mjölnir. The serpent has a symbolic body in the form of a sinusoid, to represent a pure sound.

Having exhausted the most superficial descriptions, we can say that this is the technology of digital storage of audio tracks that is more directly opposed to other audio formats such as the mentioned Mp3, ect … Compared to the latter, it allows a better audio quality through lossy compression algorithms based on psychoacoustic research. More precisely, with the same quality, the file in Ogg takes up much less space, while it occupies the same space, the quality of the file encoded in Ogg is noticeably higher: a decidedly advantageous speech if we consider that always the files in Ogg can support a maximum of 256 discrete audio channels, versus two MP3 stereos. The remarkable performance of the Ogg format is certainly worthy of praise, but what I most wish to underline is its open source nature. Free understood not as free (SL can also be purchased) but as not subject to any type of patent and with the source code accessible to all. We know well what are the advantages of open source in terms of security, but in this case, we cannot help but observe that all the advantages mentioned above are the result of the collaboration created by the possibility that it offers everyone to observe and reshape the code source. : all those who felt and those who feel capable of making a contribution can do so. And this is the greatest strength of free software: it is as if, potentially, all of humanity is called to contribute to programming! Today, Ogg Vorbis is a fully open, non-confidential, patent and copyright free flat audio format; Can your contribution help us in the project to demolish the “prisons of ideas”? what are the Copirights; at the very least, it will allow us to hear much better.

As we can easily imagine, the world of Free Software is decidedly articulated and even if we want to circumscribe our discussion in the context of programs related to the “sensory” aspects? (audio, video …), surely we can consider other names besides the surely valid Ogg Vorbis.

Let’s consider, to stay on the subject of compression algorithms, the FLAC (Free Lossless Audio Codec). Beyond its open source nature, we must consider that it is a lossless code. This means that there is absolutely no data loss, as is the case with systems similar to the MP3 model, which eliminates all sounds above 20,000Hz. FLAC’s performance is comparable to Zip’s, but with two substantial differences: FLAC is specifically designed for audio, allowing for better sound performance.

Ogg Vorbis – You should know more about Ogg vorbis

Orbis Project. This movement aims to achieve new multimedia formats in accordance with current needs and, above all, to release the rights and technological patents that cause the delay of its implementation.
These rights oblige users to pay a commission to creators, as in the case of the Fraunhofer institute.

Its advantages

Ogg Vorbis is a free, portable, and, of course, Open Source audio codec. The great asset that this sound format plays is that it is capable of producing files of a quality similar to that of MP3 at lower bitrates and with very similar storage requirements, for a better use of our hard disk or CD resources. -ROM.

Did you know…?

The Ogg project began by proposing a compression codec for freely distributed audio files, Ogg Vorbis.

They present a new version of Ogg Vorbis

The software allows you to create and run files in Ogg Vorbis format which, unlike its MP3 and WAV competitors, is 100% open and patent free. Such feature makes Ogg Vorbis have all the advantages of open source software and that its users can, for example, modify the format in order to improve it.

Another implication is that companies using the system do not have to pay licenses if they incorporate Ogg Vorbis in software products or computer equipment. In comparison, the German institute Fraunhofer, creator of the MP3 format, charges a surcharge for each MP3 product that comes onto the market.

The latest version of Ogg Vorbis, called Release Candidate 3.0, incorporates several improvements, among which the sound quality stands out.

Plug-ins for WinAmp and Windows Media Player can also be downloaded from the Vorbis.com site.

Advantages and disadvantages of the ogg format compared to mp3

There are many occasions when users of free software talk about the ogg format. Also a fairly recurring question is:

Which audio format is better? Mp3 or ogg?

After doing a little research and testing I have come to the conclusion that the ogg format is technically superior to mp3.

Furthermore .ogg files are capable of providing superior audio quality with a smaller size.

However, both file formats have advantages and disadvantages that we will detail below.

TECHNICAL ADVANTAGES OF THE OGG FORMAT REGARDING MP3

Some of the advantages of the ogg format over mp3 are the following:

Allows you to store more audio channels

The mp3 audio files only allow to store 2 audio channels. In return, ogg files allow the use of up to 255 channels.

Thus, the .mp3 format does not allow storing 5.1 Stereo surround sound (6 channels), while an .ogg file does.

The .ogg container allows storing audio and video

The .ogg container format is capable of storing both audio and video. Instead the .mp3 container can only store audio.

However in 2007 Xiph.org created the .ogv container and the Theora codec, both specific for video. Since then .ogg containers are only recommended for storing audio.

At equal file size the quality of the ogg format is superior

The Ogg Vorbis compression format is better than mp3 because it is capable of obtaining audio qualities equal to or greater than mp3, with a lower file weight.

Some of the reasons that justify what I have just commented are the following:

Ogg Vorbis is a more current audio compression format than mp3.
Ogg vorbis is free and open so that the community can continue to improve it continuously.
The quality of an .ogg file can be much higher than that of an mp3

In the case that we care a lot about the sound quality, it is better to use the ogg format:

After carrying out several tests I have reached the following conclusions:

A compressed audio to mp3 with lame at maximum quality offers a similar quality to a compressed audio with oggenc at quality 7 or 8.
The highest quality of the ogg format is 10. Quality 10 provides excellent sound quality with an average sampling rate of 520 kbps.
The maximum quality of an .mp3 file corresponds to a file with an approximate average sampling rate of 260 kbps.
Ogg Vorbis is open and patent free

The .ogg container and the vorbis codec are completely open, free, and patent-free.

Instead the .mp3 compression format is proprietary. If someone decides to encode audio files into mp3 for example to include them in a software, they will have to pay royalties to the Fraunhofer-Gesellschaft.

Labeling system is better at ogg

The ogg Vorbis labeling system is better and more flexible than the mp3 labeling system.

For example, the Vorbis labeling system allows us the following:

Edit the labels at the same time that we compress the audio files.
We can duplicate labels. In this way, if we have more than one artist, we can have 2 artist labels.
Like ID3v2 we can create custom labels. Therefore, they allow us to add practically all the information that we want.
Use a virtually unlimited number of labels.
We can use a practically unlimited number of characters to describe each of the labels.
DISADVANTAGES OF THE OGG AUDIO FORMAT

Technically .ogg audio files are better than .mp3, but currently have the following problems:

There are audio players that do not play .ogg

There are audio players that cannot play audio in the ogg format. As an example we can find the following cases:

IPods are not yet capable of playing ogg files.
Windows 10 is also not capable of playing .ogg audio by default. If we want to reproduce ogg audio we will have to install additional codecs or download some software that is capable of reproducing them.
In Mac OS the situation is similar to that of Windows. The iTunes player is not capable of playing the .ogg file format.
There are many video players that are not capable of playing the .ogg, .ogv, .ogm, etc. file formats.
My car audio CD is not capable of playing .ogg files. Instead if you can play .mp3 files.
Despite this, in many cases we can find a solution such as installing codecs or software capable of playing .ogg files

Ogg Vorbis The sound of the future?

We all know that MP3 is the standard in audio compression, but there is a solution that, according to many, has a future: the Ogg format.

Ogg Vorbis unlike the rest has no limit of use and its developers do not charge anyone for their use and much less impose their patent. In this article you will immerse yourself in the new revolution of sound for computers.

” A little history

We all know the MP3 music format which allows you to take music on the Internet with a quality similar to that of music CDs, exchange it with others, store it on your computer, store music CDs on your hard drive, listen to music on a small portable device Without moving parts.

The future of MP3 is at stake. And now they are not the lawyers, it turns out that the format itself is patented from the beginning and they will ask for a commission for use soon, so for a long time the one that will be the most advanced successor has been perfected: the OGG.

Programmers have used the MP3 freely without problems since it was born, but the fact is that the institute has the intellectual property of the format.

In September 1998, Fraunhofer began sending letters to software developers saying they plan to start charging for MP3 use licenses. Fraunhofer and the other members of the MPEG Consortium say it is impossible to create an mp3 encoder without infringing their patents.

Ogg Vorbis is a compressed audio format of high quality and general purpose (44.1-48.0kHz, 16+ bit and polyphonic, it supports up to 255 independent audio channels), which places Vorbis in the same category as MPEG-1 audio Layer 3, MPEG-4 audio (AAC and TwinVQ), and PAC.

To create or use an encoder, the law says that royalties must be paid both to the institute and to the other members of the consortium. In other words, you can listen to MP3, but you cannot contribute by recording anything in mp3.

It is a problem, the patent can limit the growth and make only those who can afford it use the mp3. They say there is no problem without a solution and OGG Vorbis is the technological solution to the challenge of MP3 patents.

In fact we can talk about Ogg Vorbis as an MPEG-4 compressor, which is trying to get ahead of the rest of competitors that exist in this format, specifically we talk about AAC and TwinVQ.

Ogg Vorbis files have the ogg extension and are only the beginning of a family of multimedia products that OggSquish is developing as part of the Xiphophorus project.

»OGG Vorbis the solution to the problem

It is an open format, that is, without an owner and without the possibility of being patented, created by volunteers in the style of free software and therefore, more technologically advanced when receiving contributions and ideas from a huge community of programmers.

It supports high quality audio, in variable bitrates, several channels and for now up to 128kb / channel. This puts OGG at the same height currently as MP3, MP4 (AAC and TwhinVQ) and PAC.

The project leader’s name is Christopher Montgomery and he started coding ogg from the moment he got the news of the patent collection threats of the German institute. Since then, there are many volunteers who have joined Montgomery while still providing ideas and lines of code, making the average OGG files 25% lower than mp3s of the same quality.

OGG Vorbis has been designed for final use, that is, you can encode everything in OGG without paying patents and never have to go back to MP3, so you can also share the OGG format on P2P networks. The most popular players already support OGG with or without extensions, as well as many reprogrammable hardware players.

The license is the GPL, it is the seed of the entire free software movement, and which allows no one to take advantage and appropriate the code that volunteers provide selflessly.

The fact that it is an open format guarantees that OGG grows and improves. MP3 is defined from the beginning, and it will never have more quality than it deserves, nor will it be smaller or more compressed, because it is closed.

OGG, however, will benefit from the improvements that the research brings and will gradually be more compressed, more optimized and sound better than it already sounds.

Live audio streaming is an important component of Vorbis. The format has been designed to be easily transmitted live.

Vorbis designers are working hand in hand with the creators of Icecast (a program for live broadcasts) to make Icecast compatible with Vorbis.

They are also working on a player that supports live ogg files. In addition, these components will soon be available from the ogg website as accessories for current players. This will be when Vorbis version 1.0 comes out.

»Unique features of Ogg Vorbis

Vorbis has a very well defined header for comments, which is extensible and easy to use, without having to use ID3 tags. Vorbis has a sampling scale, a function that allows you to change the sample amount of a file or transmission without having to recode; Simply shorten packages to the desired size.

Vorbis files can be cut and then edited with extraordinary fine sampling. Vorbis can implement multiple channels, not just one or two. In addition, files in Vorbis can be logically chained.

What is the OGG format? All about OGG

We will explain what the OGG format is and how you can open it in Windows 10. It is a free alternative to MP3 that is used to play compressed music, and in addition to being used by applications like Spotify you can also choose to use it when you go to digitize the CDs you have at home.

Let’s start by explaining in the most understandable way possible what exactly this file is and what makes it different. And then, we will end by telling you briefly how you can play it in Windows 10 very easily.

What is the OGG format?

The .ogg files are those that use the Ogg Vorbis compressed audio format, a free and open container that is developed and maintained by the Xiph.Org Foundation. The OGG has no restrictions for software patents, and has been designed to provide more efficient and high quality sound broadcasting.

You can think of the OGG as an alternative to other audio formats such as MP3, and in fact you will almost always find it in audio files with sizes similar to MP3. This means that just as there are files that can be called song.mp3, there will also be some that are called song.ogg.

Between both formats there are notable differences, such as that the compression of the OGG is lower than that of the MP3, which means that the audio quality will be better. To give you an idea, an MP3 file can have a maximum of 320 kbps, while the OGG can reach up to 500 kbps.

Files that use this audio format may also include other metadata related to the music inside, such as the track number or the name of the artist that appears on it.

The word “Vorbis” refers to the coding scheme provided by the developers of the OGG format. However, there are also OGG files that are not considered Vorbis. In these cases, you can find them using other types of audio compression such as FLAC and Speex, or using different file extensions such as .OGA.

There are also times when the OGG is used as a multimedia container, the Vorbis Multiplexed Media OGGs that use the OGX format, can have videos and can be opened with programs such as VLC or Windows Media Player. We also have the OGM extension for OGG Media files where you can find videos, although in this case it is not a format supported by Xiph.org.

However, in the vast majority of cases you don’t have to worry about that, since you will only find .ogg files to be used to play music as an alternative to MP3. In principle, it can give you the impression that the OGG is a secondary format almost unused, but keep in mind that Spotify uses this format with a quality of 320 kpps.

How to play OGG files in Windows

Fortunately, it is now very easy to play this file on Windows 10. For example, you can use it with the default music player that comes in the operating system and is called Groove Music. Simply double click on it when you have configured that application to be used by default.

You can also use some of the most popular free music playback applications. For example, the VLC player that is possibly one of the most used includes support. And if you are going to download another player, look in its features to see if it also includes support, because it is very possible that it does.

What is the best audio format? MP3? ¿OGG?

We have always used the lifelong MP3 format to store and share music, at least the vast majority. MP3 as we all know in a lossy audio compression format that saves a lot of space compared to uncompressed PCM audio (As in audio CDs).

But MP3 is not the only one, in fact, it is I think, the oldest format that is currently used today, as good audio formats with loss.

Other formats that came out later are:
* .WMA, * .AAC and * .OGG.

Recently the team xiph.org creator of OGG Vorbis has developed another audio format that I will also briefly talk about: * .OPUS

MP3 was developed by the MPEG foundation in 1994, and the biggest problem it presented was that this format had a patent for which MPEG should be paid for its use (or something like that). This was the reason why for example later the Xiph.org Foundation created the OGG Vorbis open audio format.

Today, the problem of MP3 is no longer the patent (Nowadays people use MP3 with total freedom) but since it is the oldest audio format of those in the comparison, it is the one that generally has the lowest effectiveness.

The effectiveness of one format or another also depends on bitrate among others. For example. The AAC format that uses iTunes at 192 kbps is the best compression format at this bitrate, above MP3 and OGG, but only from this bitrate.

In general, and in my opinion, at 128 kbps which is the most used bit rate and below, the best format is OGG.

The advantage of AAC (In addition to its effectiveness from 192 kbps) for what it uses itunes, is the possibility of including copyright data protection (copying).
However, at low bitrates it can be even worse than MP3.

MP3 and WMA, are in general and for my taste the worst. WMA, which seems to be a little better than MP3, was the second most used audio format in the previous decade (2000-2009). Many discmans and MP3 players were compatible with WMA, today this format is almost never used, it could be said that it has been replaced by AAC (Thanks to the popularity of Itunes).

OGG Vorbis, despite its very low popularity among people, is a very good compression format, and best of all, it is open.
Its high compression quality and open format makes it one of the favorite formats in video game developers, for example: OGG is the format chosen for the music of the GTA videogame saga, including GTA San Andreas.
OGG is also the audio format used in Spotify.

OPUS is the new audio format developed by Xiph.org as a format designed for streaming audio. It is an audio format that combines SILK (skype) codecs for spoken audio and CELT for music (CELT was the audio codec that Xiph.org was developing as a successor to Vorbis). This format is barely a couple of years old, and although it has great efficiency, it is totally focused on streaming and low latency. A great disadvantage of this format despite its effectiveness, is that the sample rate is fixed at 48000 Hz, making if for example we want to convert an audio file to 44100 hz (As in an audio CD and most MP3s) at this new frequency rate, it would have to be rescaled.

I know that it is very difficult to distinguish the quality in songs at 128 kbps, so as proof to compare the effectiveness of the different formats, I attach the song of Bon Jovi – Living on a prayer at 64 kbps in MP3, AAC, OGG formats and OPUS. All occupy almost the same, about 1.80 Mb.
To do this I will convert an original MP3 file at 160 kbps also attached, so the final quality if we converted directly from CD would be a little better maybe.
You can see the comparison yourself. In my opinion the best formats to this bitrate are in order: OPUS, OGG, MP3, AAC. Download at the top.
Did you expect this sound quality from OGG and OPUS in a file of only 1.80 mb?
