The audio formats with the best sound quality

First of all, divide all types of music files into three parts as follows:

Uncompressed file formats: .WAV, .AIFF

Lossless compression formats: .FLAC, .ALAC (Apple Lossless)

Destructive compression formats: .MP3, .AAC, .WMA, .OGG

Below are their respective advantages and disadvantages.

1. Uncompressed file format
Uncompressed music files are just like the concept of Raw files. Essentially no compression will of course have the best sound quality. (The sample rate and bit rate of the original recording are also very important. If the compressed music file is converted to an uncompressed file, the music won’t magically improve the sound quality.)

The most common disadvantage of uncompressed files is the file size. Generally, the file size of a song is around 25 ~ 40 MB. While that capacity is no longer an issue for cloud hard drives, it is still an issue for email. Also big (25MB max for Gmail attachments). Also, some portable music players or devices may not be able to play such music files.

Advantages: original sound reproduction, no compression, lossless, easier to use in post production

Disadvantages: large file format, fewer supported devices

2. Lossless compression format
The term “compressed and lossless” seems contradictory, but compression does not necessarily affect sound quality. More precisely, it’s more like “compressed to save space”. It’s like compressing a high quality file into a .ZIP and decompressing it when you want to use it, the quality of the file will not be affected.

Therefore, this type of file has a compressed capacity, but the file will be decompressed during playback to restore sound quality. Although the concept of reducing capacity without affecting sound quality is great, the downside is that support for this format is extremely low and in order to decompress the file during playback, an additional codec is required to use it, and it will. also take some performance.

Advantages: small file capacity (about 1/2 ~ 1/3 lossless files), good sound quality

Disadvantages: Decompression can eat performance when used, and support from hardware or software is extremely low

3. Destructive compression format
The destructive compression format is currently the most common music file format, the main reason is that it has the greatest compatibility with portable devices (mobile phones, MP3 players, etc.), and the files are small and have a space of limited storage. , users can store more music (compressed capacity is about one-tenth of lossless sound quality), and most of the music provided by today’s streaming media is files in this format. There is always a price to pay for smaller files. Compared to lossless formats, this destructive compression will affect the audio range that the original sound can present and will cause some distortion. So, to be safe, keep the compression rate above 320 kbps as much as possible.

What sound quality is best for the music we listen to in the car?

Listen music in the car

There are two suggestions for car music sound quality:

1. Many music lovers, who are looking for extremely high music quality, will be interested in high quality and lossless formats like OGG, FLAC or AAC.

However, due to the limited music formats that the car can recognize, music files of the above formats may not be recognized by the car.

Let alone play it.

2. In general, in the field of car music, the most commonly used formats are MP3 and WMA.

Although these formats are not as good as the ones mentioned above in terms of sound quality, they are expensive because almost all car systems can recognize them.

So, if you want to say which music file format is the best in car music, it has to be MP3 and WMA.

What sound quality is best for the music we listen to in the car?

The best audio hardware equipment is one of the most important factors that determine sound quality.

This is also related to the degree of distortion of the music being played, that is, how well the sound reproduction is restored.

This directly affects the mood of the listener. Because if the sound is loud and has no sense of hierarchy,

If you listen to it for a longer time, it will irritate you or make you feel dizzy when driving.

The other is to adjust the sound effect by yourself. After all, everyone’s sense of hearing is different.

It depends on what you adjust to make it comfortable to listen to. Adjust different parameters according to different types of music.

There will be unexpected effects.

I myself belong to the latter, although I am not a professional,

But with lossless sound quality (my car supports it, but it’s not a luxury car)

It can also bring out the feeling of fat low-frequency, clear mid-range, and bright highs (this takes some skill to distinguish),

But not all cars have sound quality adjustment.

As for the best car music sound quality, as mentioned in the article above, car music can download music with sound quality wav, ape, flac,

This is lossless sound quality, better than MP3 (as long as the device supports it).

Although now it connects via Bluetooth mobile phone or Baidu Carlife

Playing music online on mobile phones has become mainstream, but there are still a small number of people,

Insist on downloading via U disk, and use the car USB interface to play music.

What is the best audio format to get the best sound quality?

Best Audio Format

Mp3, Wav, Flac… Which one is better?

Best Audio Format

We’ve heard so many discussions about whether mp3 can sound the same as wav or flac and there are advocates for both.

There are people who staunchly defend mp3 and show and prove that an mp3 generated with certain settings can sound so similar to a WAV that not even 1% of people with ear training can distinguish it.

Others, on the contrary, argue that the method used by the mp3, causes a lot of information to be discarded in order to make the file smaller and this necessarily causes the quality to be diminished.

But everyone forgets that the number one point is to think about what kind of device or audio player we will listen to the music. Because for all these niceties mentioned above to make sense, we’ll have to have equipment that can play HD audio, otherwise we won’t easily tell one from the other.

And the truth is that most people play music on a medium quality equipment in a car on a phone or on a laptop, which makes the question of whether an mp3 sounds very different from a wav is unnecessary.

Mp4Gain is a program that manages to make audio, whatever the format, sound the best it can be.

What is the best sounding audio format? Is it MP3?

The audio formats with the best sound quality are

mp3
b, wav
c, wma
d.rm

Answer: The

B wav format files are usually stored on the computer The most widely used file format is an uncompressed format, which stores the most authentic and original sampled data, that is, the sampled data of the set frequency and bit depth they are true and lossless, like 44.1 kh/16-bit audio CD quality, other frequencies and bit depths can of course be stored.

Below are other audio file formats:

1. Format

MP3 MP3 is an audio compression technology that compresses files to a small volume on the premise of losing a certain amount of high-frequency timbre data. The highest bitrate can only reach 320K. The frequency part is basically lost.

2. Format

WMA WMA is Windows Media Audio from Microsoft. The WMA format has a higher compression rate than MP3 and the generated files are smaller. It is suitable for transmission in low-speed networks many years ago.

3. Format

FLAC FLAC is lossless audio compression. Since it is lossless compression, it will not destroy any original audio data information and can restore the sound quality of the music on the CD. FLAC is very similar to MP3, but it is lossless compression.

4. The format

APE APE is similar to FLAC and is also a lossless audio compression technology.

Something very important, that we will develop in another article and that is almost always ignored when it comes to comparing audio formats, is the equipment or device that we use to play music.

That is the point from which we should start.

Digital Audio Quality

Data rate refers to the data flow used by a video file in a unit of time, also called bit rate or bit stream rate.

The popular interpretation is the sampling rate, which is the most important part of image quality control in video encoding. Generally, the units we use are kb/s or Mb/s. Generally speaking, at the same resolution, the higher the code stream of the video file, the lower the compression ratio and the higher the image quality. The higher the code stream, the higher the sampling rate per unit time, the higher the data stream, the higher the accuracy, the closer the processed file is to the original file, the better the image quality, the clearer the image quality and the higher the decoding capability of the playback device is required.

Of course, the larger the code stream, the larger the file size. The calculation formula is file size = time X code rate/8. For example, a 720P RMVB file with a 1 Mbps stream of 90 minutes is common on the Internet and its volume is = 5400 seconds × 1 Mb/8 = 675 MB.

Generally speaking, a video file includes images and sounds, just like an RMVB video file, which contains video information and audio information. Audio and video have their own sampling methods and different bit rates, that is, the same video Audio and video file bit rate is not the same. And what we’re talking about is the bitrate of a video file, which generally refers to the sum of the bitrate of the audio and video information in the video file.

Taking the most popular and familiar RMVB video file in China as an example, VB in RMVB refers to VBR, which is short for Variable Bit Rate. The Chinese meaning is variable bit rate, which means that RMVB adopts dynamic encoding. In this way, a higher sample rate is used for complex dynamic images (singing and dancing, flying cars, wars, actions, etc.), while a lower sample rate is used for static images, and the resources are use rationally to achieve image quality and volume .Effect.

The most fundamental difference between code rate and sample rate is that the code rate is for the source file.

2. Sampling rate

Sample rate (also called sample rate or sample rate) defines the number of samples per second taken from a continuous signal to form a discrete signal, and is expressed in hertz (Hz). Sampling rate refers to the sampling frequency when converting an analog signal to a digital signal, i.e. how many points are sampled per unit of time. How many bits are in the data for a sample point? Bit rate refers to the number of bits (bits) transmitted per second. The unit is bps (bit per second). The higher the bitrate, the more data transmitted and the better the sound quality. Bit rate = sample rate x number of bits used x number of channels.

The sample rate is similar to the number of frames of moving images. For example, the sampling rate of movies is 24 Hz, the sampling rate of PAL format is 25 Hz, and the sampling rate of NTSC format is 30 Hz. When we play back the still images sampled at the same rate as the sampling frequency, we see a continuous image. In the same way, when a CD recorded at a sampling rate of 44.1 kHz is played back at the same rate, a continuous sound can be heard. Obviously, the higher the sample rate, the more coherent the sound will be heard and the picture will be seen. Of course, the sampling rate that human auditory and visual organs can distinguish is limited, which is basically higher than sound sampled at 44.1 kHz, and most people haven’t noticed the difference.

The number of digits in the sound is equivalent to the number of colors on the screen, indicating the amount of data per sample. Of course, the larger the amount of data, the more accurate the playback sound, so as not to confuse the sound. of the teapot with the train whistle. In the same way, it is more clear and precise for the image, so as not to confuse blood and ketchup. However, limited by the function of human organs, 16-bit sound and 24-bit image are basically the limits of ordinary humans, and the highest digits can only be distinguished by instruments.

Detailed Music Format Part 2

Music CD

That is, CD records. A CD can play sound files of approximately 74 minutes. The Windows system comes with a CD player. Also, the software that comes with most sound cards provides CD playback functionality, and even some CD-ROM drives are offline. from computer Can be used as a stand-alone CD player when powered on.

WMA with unlimited potential

In developing its own network media service platform, Microsoft primarily promotes ASF (Audio Streaming Format), which is an open standard that supports data transmission over various networks and protocols. It supports audio, video, and a variety of other types of multimedia. And WMA is short for Windows Media Audio, which is equivalent to an ASF file that contains only audio.
The compression ratio of WMA files can be as high as 1:18 in 80kbps 44kHz mode, which is basically the same as VQF. And the compression speed is doubled compared to MP3. So it should be more competitive than VQF.

Vorbis free music format

To avoid rising royalties charged by MP3 music companies, programmers at GMGI’s iCast company developed a new free music format, Vorbis, that rivals or even exceeds MP3 in sound quality. And it will be released over the internet and can be downloaded for free without worrying about infringement issues. But MP3 has become very popular on the Internet, and Microsoft’s Windows Media technology has also started to spread, and Vorbis’s outlook is still not optimistic.

Other audio formats

AIF/AIFF: A sound file format developed by Apple, supported by the MAC platform, and supports 16-bit stereo at 44.1 kHz.
AU: SUN’s AU Compressed Sound File Format, which only supports 8-bit sound, is a commonly used sound file format on the Internet, mainly created by SUN workstations.
CDA: CD audio track file.
CMF: A MIDI-like sound file developed by CREATIVE.
DSP: Abbreviation for digital signal processing. By improving the signal processing method, sound quality will be greatly improved and songs will be more pleasing to the ear.
S3U: MP3 playback file list
RMI: MIDI Instrument Sequence

Lossy compression:

AAC – Sound quality is second only to MPC at high bit rates and looks good at both high and low bit rates. The encoding speed is too slow!
MPC: Performance is average at low bitrate, not as good as MP3 and OGG encoded by Mp3Pro, sound quality is best at high bitrate, and encoding speed is
fast.OGG: The sound quality is better at a low bitrate, and the same is true at a high bitrate. Encoding is slightly slower.
MP3 (MP3Pro): Sound quality is lower than OGG at low bit rate and other aspects are the same as MP3
WMA: High and low bit rates are average, VBR is not supported and the highest is 192Kbit/s

lossless compression:

FLAC – Worst compression ratio of the four, decent encoding speed, good platform support.
PAC: Slightly slower encoding speed, third in compression ratio, good platform support.
APE: The fastest encoding speed, the best compression rate, and the platform is generally supported.
WV: The encoding speed is very fast, the compression rate is second among the four types, and it is only supported by the Windows platform.

Detailed music format

classic wave

As the most classic Windows media audio format, the WAVE file is widely used, which uses three parameters to represent sound: the number of sampled bits, the sample rate, and the number of channels.
The channels are divided into mono and stereo, and the sample rates are generally 11025 Hz (11 kHz), 22050 Hz (22 kHz), and 44100 Hz (44 kHz). The capacity occupied by the WAVE file = (sampling frequency × sampling bits × channel) × time/8 (1 byte = 8 bits).

traditional mod

MOD is a wavetable-like music format, but its structure is similar to MIDI, it uses real samples, and the volume is small. In the earlier DOS era, MOD was often used as background music for games. Modern mods can contain many audio tracks in many formats, such as S3M, NST, 669, MTM, XM, IT, XT, and RT.

midi music computer

MIDI is short for Musical Instrument Data Interface. Records the sound played by the instrument digitally (each note is recorded as a number), and then synthesizes these records via FM or wavetable during playback: FM synthesis is the sound of the instrument is simulated by mixing the multi-frequency sounds; wavetable synthesis consists of storing the sound samples of the instrument in the wavetable of the sound card and extracting the sound from the wavetable as you play.

Boss Boss MP3

It can be said that MP3 is famous, it uses MPEG Audio Layer 3 technology to compress the sound with a compression ratio of 1:10 or even 1:12, with a sampling rate of 44kHz and a bit rate of 112kbit/s. .
MP3 music is music stored in digital form. If you want to play it, you must have a corresponding digital playback and decoding system. Generally, MP3 digital music is decoded by special software and then restored to a waveform sound signal for playback output. This type of software is called For MP3 players, such as Winamp, etc.

Overlord RA series online

RA, RAM, and RM are Real’s mature network audio formats, using “streaming audio” technology, making them well suited for network streaming. Information such as copyright, singer, producer, mail and song title can be added during production.
RA can be called the supreme lord of multimedia communication on the Internet. It is suitable for streaming on the Internet and is currently the best format for listening to online music online.

VQF with high compression ratio

VQF or TwinVQ is an audio compression technology developed by Nippon Telegraph and Telephone and Yamaha Corporation.
The audio compression rate of VQF is almost twice that of standard MPEG audio and can reach approximately 1:18 or even higher. And popular compression formats like MP3 and RA are usually only around 1:12. But it still won’t affect the sound quality, when VQF compress music at 44kHz-80kbit/s audio sampling rate, its sound quality will be better than 44kHz-128kbit/s MP3, when compress at 44kHz-96kbit/s , the music is close to 44kHz-256kbit/s MP3.

MD minidisc

MD (ie MiniDisc) is a comprehensive portable music format released by SONY in 1992. The compression algorithm it uses is ATRAC technology (the compression ratio is 1:5). MD is divided into Recordable MD (Recordable, with two heads of magnetic head and laser head) and Single Play MD (Prerecorded, only laser head).
The powerful editing function is the strong point of MD. You can quickly select tracks, move tracks, merge, split, delete and edit track titles. It is more personalized than CD and you can have your own MD album at any time. MD products include MD Walkman, MD bedside audio, MD car audio, MD recording deck, MD camera gun and MD driver, etc.

What audio format should I choose?

What audio format should I choose?

Best Audio Format
Everybody loves music. Some listen to it on the way to work, and others can’t go a minute without their favorite songs. Listening to music comfortably depends not only on the mood, the time, the moon phase and good headphones, but also on the audio format in which it is stored on our devices.

In the 21st century, streaming services are becoming popular, but most people still store music offline and listen to it from their phones, players, audio systems, etc. But this post is not a discussion “Which headphones are better?”, “Why listen to music?” or “Why vinyl, not CD?”, but a brief summary of today’s most popular digital audio formats, their pros and cons. I will not analyze them all, and I will not compare different encodings, the differences “this AAC from this AAC”, but I will try to count in an accessible way the differences of some popular audio formats from each other.

So what is the best way to store your music collection? Today, there are many digital audio formats, and if you want, you can see a list of them on Wikipedia. But we will focus only on MP3, AAC, WMA and FLAC.

MP3

The most popular audio format and nobody can argue with that. Why is it so popular? It’s simple, because Mp3 was the first audio format with the best ratio (at the time) of file size and quality when compressed. Therefore, most of the songs were translated into MP3, which served as the undisputed primacy of the audio format on the market.

The advantages are clear from the previous paragraph: small size, tolerable compression loss, ubiquity, compatibility with all devices, and also, due to the small size, you can store a large collection of songs on a medium with little memory capacity, which it is also an advantage for some.

But Mp3 also has some disadvantages. Even though compression losses are not visible to ordinary people, knowledgeable people will notice them immediately. This is a low sound quality compared to other audio formats, as well as a “cut” of frequencies above 17 kHz, which is felt by ear with good headphones.

AAC

The young audio format AAC, mainly promoted by Apple, can be considered the successor to Mp3. AAC seems much more advantageous because Compared to MP3, AAC file compression is more efficient. At a bit rate of 128 kbps, an AAC composition is comparable in sound quality to the same MP3 composition at a 192 kbps bit rate.

Better compression quality is a major advantage of AAC. The disadvantage is not the same prevalence as in the same mp3. Some devices do not yet support this format. And also the compositions in AAC take up more space than in MP3. Not as much as FLAC, but still, for some it is a critical factor.

WMA

The WMA format was created by Microsoft as an alternative to Mp3 for Windows users. It was believed that with half the bit rate of MP3, WMA produces similar quality. But, in fact, the composition in WMA at 128 kbps is noticeably lower than that of Mp3. The advantages include full Windows support, but the disadvantage is extremely low quality at a low bit rate. By personal observation, I will say that I have not seen people storing their music in this audio format for a long time.

FLAC

One of the most common audio formats for music lovers in good quality. FLAC compresses the data, leaving it in the output identical to the original, without losing any data, which is the main lossless compression algorithm. Furthermore, decoding the FLAC format does not require as much processor resources, allowing you to listen to music on portable devices.

The advantages of music in FLAC are excellent quality and fast decoding, but a disadvantage, as a result, is the large file size.

So in what audio format should you keep your music collection? If you are not so critical of losses after compression, if you want to make a mistake with the support, so that your collection does not become a bunch of useless files in 5 years, you have a limited amount of memory for your music, then choose Mp3. If free space allows you to store larger files, switch to AAC. I personally don’t recommend WMA. I think this audio format is dead, although most people will not agree with me. And if quality is important to you, you have a good audio system or headphones, and even minimal compression loss is inexcusable for you, then FLAC definitely is. But be prepared for the fact that you must have plenty of room for music.

The best popular audio formats

The best popular audio formats

I looked around the forest of audio formats for normal use and chose the 5 most important ones. It is true that, in part, a bit simplified, a bit rough in presentation. I refrain from differentiating the exact settings of the respective codecs, that would be too complex.

I also don’t want to get into the nasty topic of DRM. The most important one I dropped is probably Vorbis. . Of course, I assume that the correct settings are used when encoding and that a high quality level is selected.

1st place:
MP3 (MPEG-1 Audio Layer 3)

The most widespread digital format, with good encoding (for example, with LAME) in high bit rates, a format of the highest quality and transparency.

Quality (4.5 / 5 points)
Popularity (5/5 points)
Compression (4/5 points)
Total: 13.5

2nd place:
AAC (advanced audio coding)

It became famous especially for its use in the Apple iPod, a codec that has small advantages over MP3 at low bit rates due to technical developments.

Quality (4/5 points)
Popularity (4.5 / 5 points)
Compression (4.5 / 5 points)

3rd place:
WMA (Windows Media Audio)

Windows proprietary format. Of course, Microsoft has the reins here, so variable format doesn’t run on all playback devices. Otherwise, no major strengths and weaknesses and, for example, the standard format with Napster.

Quality (4/5 points)
Popularity (4/5 points)
Compression (4/5 points)

Total: 12

4th place:
FLAC (Free Lossless Audio Codec) !!

As the only lossless codec on this list. FLAC works in something like a ZIP program: the original can be restored from the compressed file by approximately 50% without restrictions. In times of low hard disk space, a real alternative, especially since many playback devices can play this format. My winner of hearts, the popularity will certainly increase in the future.

5th place:
Wav

The original format of the normal audio CD data. Impeccable quality and still widespread thanks to the well-known compact disc. It actually started out of the competition because it’s completely unzipped.
