What music file format is recommended? Part 2

AUDIO FORMATS

Opus is a new audio compression format developed by the IETF and standardized by RFC6716 in 2012. There is very little hardware and software supported, but at low bit rates of 128 kbps or less, it appears to be the strongest sound quality with compression with lost.

audio formats

Vorbis is a free audio file format developed by Xiph.org. It seems to be used on Youtube too. Since the standard bit rate is 112 kbps, the sound quality at a low bit rate appears to be good.

WMA is a standard Windows audio compression method developed by Microsoft. If the bit rate is 160 kbps or less, it exceeds the MP3 upper limit frequency. However, the size will be a little larger.

AAL (ATRAC Advanced Lossless) is a lossless compressed version of ATRAC mentioned above. According to Sony, it can be compressed to about half the size of the data without losing any music information on the CD, but it actually seems to vary considerably depending on the sound source.

As the name implies, Apple Lossless (ALAC) is Apple’s lossless compression audio codec. Used in iTunes, etc.

FLAC is an audio file format developed and distributed as free open source software. It seems to be the most popular in lossless compression.

Monkey’s Audio is an audio format that compresses PCM losslessly without degrading sound quality. It is so named because it is used in music playing software called Monkey’s Audio. The characteristic is that it does not fit the name and the compression rate is high.

TAK is a high-speed, high-compression, lossless compression audio encoder. It has the same level of compression as Monkey’s Audio, but it’s pretty crazy.

TTA is a free real-time lossless compression audio encoder / decoder. Like TAK, it’s too manic so I wouldn’t use it.

WMA Lossless is a lossless compressed version of WMA mentioned above.

Equalizer Image
AIFF is an uncompressed audio file format developed by Apple. It seems to be the Windows WAV. It seems to have been used on Macintosh (Mac) for a long time.

WAV (WAVE) is a format for describing audio data developed by Microsoft and IBM. This is what happens when you convert a CD (Linear PCM) into an uncompressed file in Windows.

Also, the sound quality of lossy compressed music file formats is almost the same at 192 kbps bit rates. If it is 160 kbps or less, I am wondering if other compression formats are slightly better than MP3. In this case, it is better to check the music player software. Sound quality is exactly the same for lossless and uncompressed music file formats. Lossless compression will have issues with compression ratio and playback load.

What is free high-quality music player software for Windows?
After all, what music file format is recommended?
Image of listening to music with a portable music player
I’ve mentioned it so far, but I recommend MP3 or WAV (AIFF). The reason is as follows.

Due to the large capacity of hard drives and flash memory, lossy compressed music file formats do not need to have a bit rate lower than 192 kbps.
The compression ratio of the lossless music file format is currently 60 to 70% maximum, so taking into account the encoding time and effort and loading during playback, the file format of Uncompressed music is sufficient for lossless compression.
I don’t think I can distinguish between 192kbps MP3 and WAV, so I can’t help but worry about the compression format.
MP3 and WAV have many compatible hardware and software.

What music file format is recommended?

What music file format is recommended?

audio format

There are many types of music file formats, so it is difficult to know which one is recommended.

AUDIO FORMAT

I have only used MP3 and WAV due to their confusion, so I don’t really know about the new music file formats that are increasing year after year. So, I took a quick look at the existing music file formats based on the information from the internet. Let’s make a list of types and extensions so that you can easily understand them later.

* The target is a music file format that can be converted from a CD (linear PCM).


* The format can be replaced with the term codec and the extension can be replaced with the term file format. Simply put, a codec is a device or software that can encode (encode) and decode (decode) data in both directions using one encoding method. A file format is an information device like a computer. It is the storage format of the file used in.

* The bit rate for lossy compression is 192 kbps.

* The corresponding items indicate the amount of hardware and software that the music file format supports. ◎ Many, ○ Many, ▲ Normal, △ Less, × Very few.

Currently, lossless compression is emerging as a compression format in addition to lossy compression. Irreversible compression (lossy compression) is a data compression method in which the data before compression and the data after compression do not completely match, and reversible compression (lossless compression) is the data before and after compression. It is a data compression method that exactly matches the data.

In other words, lossy compression is a poor sound quality compression method because it adds a reduction in the amount of data, and lossless compression is a good sound quality compression method because it does not reduce the amount of data. . They are all the same in the sense that they aim for high sound quality with the smallest possible size.

Now, I’m sure there are music file formats that you already know, but let’s briefly explain each one.

Mixer Image
AAC is a music file format standardized in 1997 (approved in 1999). Standardized in order to obtain high sound quality and high compression that exceeds MP3. If the bit rate is 160 kbps or less, it exceeds the MP3 upper limit frequency.

ATRAC is a voice data compression technology developed by Sony since 1992. If the bit rate is less than 128 kbps, it is above the upper frequency limit of MP3.

HE-AAC is a music file format standardized in 2003. By incorporating SBR technology into the aforementioned AAC, the playback band has been expanded and the sound quality and compression efficiency at low bit rates (128 kbps or less) have been vastly improved.

* SBR (Spectral Band Replication) is a technology for audio compression and encoding, which aims to strengthen the conventional encoding method and increase the compression rate.

MP3 is the oldest music file format standardized in 1991 (approved in 1993). Since it is old, it has a high penetration rate and there is a large amount of supported hardware and software.

There are many types of voice file formats, as well as image file formats.

Audio Files

Since the digital audio files are easy to copy, the illegal copy and distribution of music files has become a problem these days.

As explained in what analog data is, the mechanism of digital audio files is that analog signals become digital data and are saved.

Explaining in detail the conversion method, to convert an analogue to digital waveform, it is necessary to perform a job called “sampling” that measures (record) the sound waveform at regular intervals, and is the sampling cycle. The sampling frequency is called (sampling frequency).

The sampling frequency represents the number of samples per second and is in Hz. In other words, it is a unit that expresses how many times the sound is measured and recorded per second, and the greater the value, the more faithful the original and greater sound becomes the quality of the sound. However, the amount of data will increase proportionally.

The sampling frequency of a typical music CD is 44.1 k Hz. However, even if the sampling frequency is increased, there are sounds and frequency bands that can not really be recorded, so some classical music enthusiasts love expensive analogue equipment.

In addition, it is not only the sampling frequency, which affects the quality of the sound, but also the “sampling bit” that indicates the strength (volume) of the sound (16 bits are 65,535, 24 bits are 16,777,215). (Express) and “Number of channels” (number of sound lines recorded as stereo, monaural and 5.1 channels) also have an effect. The higher the value, the greater the sound quality.

Another factor that greatly affects sound quality is the bit rate. The bit rate represents the amount of data to be recorded per second and the unit is “BPS”.

In other words, the higher the bit rate, the more information can be stored, which results in a higher sound quality. As will be described in detail below, in the MP3 file format, 128 K BPS is the minimum bit rate that can be heard.

However, there is “constant bit rate” and “variable bit rate” in the bit rate. The constant bit rate is the same bit rate that is fixed from the beginning to the end of the voice, and the variable bit rate increases or decreases the bit rate according to the amount of voice information.

In other words, the bit rate is high for clauses with multiple voices and the bit rate is low for simple low voice clauses. You can reduce the total size of the file by choosing a variable bit rate.

This is the information contained in the digitized data of analog audio signals.

However, digitized data can not be used as. Just converting this data into an arbitrary file format and saving them, it will be possible to use them with multimedia devices and application software that admit that format.

The storage format of said data

file format

Is named. A file format is a file format with an extension.

Then, to save the data in a file format, it is necessary to transform (encode: encoding) the data according to that format. (For coding, see What is a character code?)

A dedicated program is used to codify the data, but said coding program is

Codec (codec)
Is named. In other words, the gross data obtained by converting analog signals into digital data are processed by a codec to market them as a file format.

Therefore, there are many types of codecs and coding methods for each type of codec.

Most current codecs are programs that compress and encode data when creating a file and decompress (decompress) data by playing a file. In general terms, codecs are used to compress and decompress data. It refers to a compression method program of this type.

Audio File Formats

Apart from M4A, there are many other active audio formats. For example, the popular MP3, AC3, WMA, OGG, etc.

Audio Formats

 

What is the difference between M4A and MP3, AC3, WMA? What is better about M4A than MP3, AC3, WMA and OGG? Then read the next sentence to see the battle in audio compression format.

M4A and MP3: Both M4A (MPEG 4 audio) and MP3 (MPEG3 audio) are audio compression formats developed by the Motion Picture Experts Group (MPEG). Next, I will introduce the differences between M4A MP3 in terms of file size, sound quality and compatibility.

Sound Quality: The M4A format, known as Apple Lossless Encoder, aims to replace MP3 with a new standard for audio compression. However, when comparing M4A MP3 for sound quality, M4A is better. Generally speaking, it is recommended to store music with M4A audio at 192 kbps bit rate for good sound quality and small file size.

File size: In terms of file size, M4A is often believed to have superior sound quality than MP3 when encoded at the same bit rate. For example, with 128-bit AAC (M4A), a 4 minute song would be 3.8 MB. To maintain the same sound quality with MP3, it is necessary to encode at a rate of approximately 192 bits. Then the file size will exceed 3.8MB.

Compatibility: Currently, M4A is only used on PC, iPod and other Apple devices and is not as popular as MP3. In contrast, all computers, music players, and mobile phones can play MP3 files.

Tip: If sound quality is a priority, neither M4A nor MP4 is the best option. It is advisable to choose the uncompressed WAV format. However, the size of the WAV file is about 10 times that of M4A and MP3. Therefore, WAV, which takes up too much space when creating a music collection, is not the best format.

M4A, MP3 and WMA: WMA A lossy compression codec developed by Microsoft. Like other new formats, M4A and WMA have higher compression efficiency and better sound quality than MP3. Sound quality is particularly good at low bit rates. As a result, WMA works well for low-bandwidth video streaming. Therefore, songs purchased from online music stores Napster, Musixmatch, and Wal-Mart must be stored in WMA. However, WMA cannot be played on Apple iPod, which is a shame.

If you take a normal audio CD with analog sound, burn it in WAV format for uncompressed sound, then compress WAV using lossless codec, then unzip the resulting audio file into WAV and burn the result to a blank CD, you can get two completely identical audio CDs.

The advantage of lossless for storing an audio collection is that the quality of the recordings is much higher than that of lossy codecs and they take up less space than uncompressed audio. It is true that lossy files are smaller than lossless music files. Most modern playback programs understand the lossless format. Those programs that cannot play it can easily learn it using the lossless plugin. What are lossless audio formats?

Lossless audio formats

A true music lover is unlikely to be satisfied with the sound of music recorded in Ogg Vorbis or MP3 compression formats. Of course, if you listen to audio recordings on home audio equipment, sound defects cannot be heard with your ear, but if you try to play a compressed file on high-quality Hi-Fi equipment, you will immediately find sound defects. . Of course, creating a collection of quality music on CD or vinyl is not easy. There is a reasonable alternative to this path for lovers of high-quality sound – lossless music. It can be stored on your PC in a format that allows you to keep the original music settings unchanged, even if compression is applied. In this way it simultaneously solves the problems of high-quality music and its compact storage, since the audio equipment for listening (headphones, speakers, amplifiers) is quite affordable.

Description of the FLAC extension
Popularity: Frequently used

Section: Audio files

Developer: flac.sourceforge.net

The FLAC extension is an acronym for Free Lossless Audio Codec, an open source audio format that uses lossless audio compression, which means that the audio is compressed into the FLAC format without loss of quality or original data.

In simple terms, FLAC is similar to MP3 but is lossless, which means that the audio is compressed into FLAC with no loss of quality. This is similar to how ZIP works, but in the case of the .FLAC file, you will get much better compression as it is specifically designed for audio, and you can play the compressed FLAC files on your favorite player (or in your car, or in your home stereo system), just like you would play an MP3 file.

FLAC files are freely available and compatible with most operating systems, including Windows, “Unix” (Linux, * BSD, Solaris, OS X, IRIX), BeOS, OS / 2, and Amiga. Systems have been created for Autotools, MSVC, Watcom C, and Project Builder.

To avoid as much as possible a decrease in sound quality during the compression of an audio file, special methods have been developed to store audio information, avoiding losses, which in fact can be compared with the file, when the information is simply packed in a zip file, the size of which is significantly smaller than the original data. Subsequently, this data can be clearly restored on each bit. Also, the bit rate itself is not important for these files. These audio files are collectively called Lossless, Music As Is. These algorithms allow you to compress files two to three times. As a result, the size turns out quite large, but at the same time with the preservation of the original sound.

The most popular lossless formats are as follows.

FLAC
Audio Formats The abbreviation is the name “Free Lossless Audio Codec”. Provides complete security of all data in the audio stream, capable of 1.4 to 4x compression with 350-1010 kbps bit rate, used to create audio collections, and used for listening on premium equipment .

Pros:
– high quality;
– a large number of additional features;
– free license.
Disadvantages:
– quite large size;
– on older operating systems, you must additionally download the appropriate players.

Wav
Audio Formats Waveform audio format is one of the oldest formats that was created by Microsoft together with IBM. It is the best audio format for processing and storing uncompressed audio data in CD-like quality. One minute of sound “weighs” about 10 MB. Therefore, it is not recommended to store a music library in .wav or send these audio files over the Internet.

Pros:
– impeccable quality;
– Instant unpacking – “on the fly” with economical use of the processor;
– wide distribution and support of a large number of programs and audio devices.
Disadvantages:
– a lot of weight.

A THE C
Audio Formats
To store lossless compressed information on Apple devices. In terms of compression ratio, it is slightly lower than free FLAC.

Pros:
– there is no loss of quality when copying from a CD;
– the ability to easily convert to any other audio file format with good quality;
– restoration of a collection of CDs by recording new ones with the same quality instead of damaged ones.
Disadvantages:
– big size;
– limitations on compatibility with audio devices.

MONKEY
Audio Formats Monkey’s Audio is a fairly popular format that is released for Windows, but it has several unofficial codecs for other platforms. The format supports 8-, 16-, and 24-bit audio files, so it is widely used in the professional field.

Pros:
– high compression ratio and data processing speed;
– the possibility of direct reproduction of compressed information;
– support for information labels and, as a result, the ability to create convenient sound files.
Disadvantages:
– limited support.

Where can I find lossless music?
Listening to lossless music is a real treat. Also, if ordinary desktop speakers are used for a cheap computer or headphones, the full potential of lossless formats cannot be revealed. This requires high-end audio equipment: turntables, speakers, amplifiers, premium headphones, and even high-quality cables. At the same time, a question remains: where to get music in these formats?

Today, together with AudioCD, you can have high-quality music always at hand. This is facilitated by online music streaming services, which are constantly growing in popularity.

The FLAC audio file format

Flac

The FLAC format was developed by the staff of the Xiph.org website. It was used to compress audio files. Compression does not result in loss of quality, which means that no data is lost during this process. The FLAC format allows users to maintain the original quality of the files; it is this property that makes the format an ideal method for backing up audio data, as physical media can deteriorate over time. FLAC files are used for high-quality audio backup from CD. the quality of MP3 files is poor. FLAC files are completely free of charge and widely available. Tools to verify the integrity of records, metadata, and images can be added to the format.

Technical details of FLAC files
Due to the high encoding speed, FLAC files are usually at least 50% smaller than the original file size. However, such compression does not result in any loss of quality. FLAC files are often used for online streaming and real-time online encoding. In this case, a FLAC project contains the following elements: stream format, container format, reference codec library, and input plug-ins. The FLAC format supports fixed point samples with PCM bit ranges from 4 to 32 bits per sample and sample rates up to 655,350 Hz (channels 1 to 8). When new fields are added, existing decoders feel no impact thanks to the protection of FLAC files.

flac audio format

A FLAC (Free Lossless Audio Codec) file is an audio file that has been compressed without losing sound quality. The .flac file format is considered inferior to MP3 in terms of compression ratio, but FLAC clearly demonstrates the best sound quality results.

FLAC files are very popular among connoisseurs of listening to audio on high-end stereos. Many music lovers prefer to create their own audio collection, where the FLAC format helps improve the quality of listening to music.
There is a type of FLAC Fingerprint file attached, named “ffp.txt”, which stores the data from the .flac file itself, as well as a checksum.

With the right software, the user will be able to listen to this file extension without any problem. There are a large number of all kinds of players distributed for free. The most popular are Nullsoft Winamp and AIMP Player, and VideoLAN VLC Media Player. You should know that you can open a FLAC file using Windows Media Player; however, for full Lossless Audio format operation, you will need CoreFLAC / Illiminable filters.

You can edit the FLAC file format with Adobe Audition or Sound Forge. The hardware of certain mobile devices is also capable of opening a FLAC file. Some users prefer to convert FLAC to another format due to the large amount of memory consumed, but for those who are interested in high sound quality, the FLAC extension will give them a real pleasure in listening to music.

How about high definition music?

Audio Formats

Unlike HD video, there is still no universal standard for high definition audio.

Without going into detail, this term generally refers to recordings with a higher sample rate and / or bit depth than CD (i.e. 16 bit / 44.1 kHz). Examples of high-resolution audio are 16-bit / 96 kHz or 24-bit / 192 kHz files.

Due to the presence of additional audio information, high-resolution files sound much better than compressed files, which lose this information during the compression process. These formats require more disk space, but their quality is definitely worth the investment.

High-resolution audio includes uncompressed formats, such as AIFF and WAV, and lossless formats, such as FLAC and ALAC. DSD (partly a niche format used on Super Audio CDs) also falls under the Hi-Res Audio category, but it is compatible with a much smaller number of devices. When it comes to streaming, services like Tidal Masters use an MQA container to stream high definition files over networks using the lowest possible signal bandwidth.

When it comes to playing high-resolution audio formats, it is already supported by many devices today. The 24-bit files can be played with Denon HEOS wireless speakers, as well as premium portable music players like Cowon Plenue D2 and Astell & Kern A & norma SR15.

Also, most flagship Android smartphones support Hi-Res Audio, for example the highly rated Samsung Galaxy S10 +, but you won’t be able to immediately hear them on a new iPhone. We’ve found ways around this limitation, but keep in mind that Hi-Res Audio files are still not as compact as their lossy counterparts.

What is the best audio format for you?
The format you choose depends on whether you are more concerned about memory capacity or sound quality, and what type of device you intend to use it with.

The popularity of MP3s came at a time when the cost of disk space was very high. Today’s smartphones, music players, and laptops are equipped with an impressive amount of memory, so it makes sense to pay attention to higher-than-CD quality formats.

If you have decided to archive your audio files, FLAC or another lossless format might be a good option. They represent a good compromise between compression level and sound quality, allowing you to listen to high-quality digital music and save disk space. Just be sure to check the compatibility of the selected format and available devices.
