What is an audio codec?

An audio codec is a type of software that compresses and decompresses audio files. This process makes the audio smaller, so it can be easily stored and shared on your computer, phone, or online. When you want to listen to the audio, the codec decompresses it so you can hear it in its original quality.

Why are there different codecs?

Just like how you can choose between different types of ice cream flavors, there are different types of codecs because everyone has different tastes and preferences. Some codecs are better for music, while others are better for speech. Some are easy to use, while others are more complex. The choice of codec depends on the type of audio you want to compress, the size of the file, and the quality of the sound you want to preserve.

The most popular codecs

There are many different audio codecs out there, but here are some of the most popular ones:

  • MP3
  • AAC
  • FLAC
  • WAV

MP3

MP3 is one of the most popular codecs and has been around for over 20 years. It’s a great choice for music because it compresses audio files into smaller sizes while still preserving the quality of the sound. MP3 is also compatible with most devices and players, making it a convenient option for many people.

AAC

AAC stands for Advanced Audio Coding and is a newer codec that was developed by Apple. It’s commonly used by Apple devices, like the iPhone and iPad, and provides better sound quality than MP3 at a lower bit rate. AAC is also used by many online streaming services, like Spotify and Apple Music, to deliver high-quality audio to their users.

FLAC

FLAC stands for Free Lossless Audio Codec and is a popular option for audiophiles. This codec compresses audio files into smaller sizes without losing any quality, making it the perfect choice for people who want the best sound possible. The downside to FLAC is that it’s not as widely supported as MP3 and AAC, so you may need to use special software to play FLAC files on your device.

WAV

WAV is a common codec for professional audio and is often used in recording studios. It’s a lossless codec, which means it doesn’t compress audio files and preserves the original sound quality. However, WAV files are usually much larger than files compressed with other codecs, so they may take up a lot of space on your device.

Conclusion

In conclusion, the choice of codec depends on the type of audio you want to store and share, and your personal preferences. MP3 is a classic and widely supported option, while AAC offers better sound quality. FLAC is the perfect choice for audiophiles who want to preserve the original sound quality, and WAV is used in professional settings.

As an enhanced version of mp3, mp3PRO shows pretty good quality, with full treble. Although mp3PRO is inserted during playback via SBR technology, the actual listening experience is quite good. Although it seems a bit thin, you are already in the world of 64 kbps. There is no rival, even more than 128kbps mp3, but unfortunately, mp3PRO’s low-frequency performance is also broken like mp3, fortunately, SBR’s high-frequency interpolation can more or less cover this shortcoming, so mp3PRO’s weakness. low frequency is not as obvious as that of WMA. You can feel it deeply when you use the PRO switch of RCA mp3PRO Audio Player to switch between PRO mode and normal mode. In general, the 64kbps mp3PRO reaches the level of sound quality of the 128kbps mp3 and wins slightly in the high frequency part.
Features: The king of sound quality at low bit rates.
Applicable to: Music appreciation with low requirements.
BUN
An emerging lossless audio encoding that can provide 50-70% compression ratio.

MP3

MP3

MP3 has a good compression ratio, and the medium and high bitrate mp3 encoded by LAME is very close to the source WAV file in the listening sense. With the right parameters, LAME encoded MP3 is very suitable for listening to music. Since MP3 has been around for a long time, along with its good sound quality and compression ratio, many games also use mp3 for event sound effects and background music. Almost all well-known audio editing software also support MP3, you can use mp3 as wav, but because mp3 encoding is lossy, after several edits, the sound quality will decrease drastically, mp3 is not suitable for saving material, but the demonstration as a work is actually quite excellent. The long history and good sound quality of mp3 make it one of the most widely used lossy codecs. A lot of mp3 resources can be found on the Internet, and mp3player has become a trend day by day. Many VCD players, DVD players, and even mobile phones can play mp3, and mp3 is one of the best supported encodings. MP3 is also not perfect and does not work well at lower bit rates. MP3 also has the basic features of streaming media and can be played online.
Features: good sound quality, high compression ratio, compatible with a large number of software and hardware, and widely used.
Applicable to: Suitable for music appreciation with relatively high requirements.
OGG
Ogg is a very promising codec that works surprisingly well at various bit rates, especially medium and low bit rates. In addition to good sound quality, Ogg is also a completely free codec, which lays the foundation for further compatibility with ogg. OGG has a very good algorithm which can have better sound quality with smaller bitrate, and 128kbps OGG is better than 192kbps or even higher MP3. OGG’s treble has a certain iciness to it, so the OGG flaw will be exposed when encoding some musical instruments with high-frequency requirements. OGG has the basic features of streaming media, but there is no media service software support, so ogg-based digital streaming cannot be done. Ogg’s current support situation is not good enough, either software or hardware, it can’t compare with mp3.
Features: It can achieve better sound quality than mp3 with lower bit rate than mp3 and has good performance at high, medium and low bit rates.
Suitable for: Better sound quality with less storage space (relative to MP3).
MPC
Just like OGG, MPC’s competitors are also mp3. At medium and high bit rates, MPC can achieve better sound quality than the competition. At medium bit rates, MPC’s performance is not inferior to Ogg’s. At high bit rates, MPC performance Performance is even higher Hard to beat. The sound quality advantage of MPC is mainly reflected in the high-frequency part. MPC’s high frequency is much more delicate than MP3’s, and doesn’t taste like Ogg’s ice cubes. It is currently the most suitable lossy encoding for music appreciation. Since they are all nascent code, similar to the Ogg encounter, they also lack extensive software and hardware support. MPC has good encoding efficiency and the encoding time is much shorter than OGG and LAME.
Characteristics: At medium and high bit rates, it has the best sound quality performance in lossy encoding, and at high bit rates, it has excellent high-frequency performance.
Ideal for: Listening to music with the best sound quality while saving a lot of space.
WMA
WMA developed by Microsoft is also loved by many friends. At low bit rate, it has much better sound quality than mp3. The appearance of WMA immediately eliminated the once popular VQF encoding. WMA with Microsoft background has got good software and hardware support, Windows Media Player can play WMA, and can also listen to digital radio stations based on WMA encoding technology. Because the player exists on almost every PC, more and more music sites are happy to use WMA as the first choice for online listening. In addition to the good support environment, WMA also has a very good performance under the bit rate of 64-128Kbps. Although many friends with higher requirements are not satisfied, more friends with low requirements have accepted this encoding, and WMA is very good. . Quickly popularized.

PCM encoded WAV
As mentioned above, PCM encoded WAV file is the format with the best sound quality and on Windows platform all audio software can support it. There are many functions in WinAPI provided by Windows that can play wav directly, so when developing multimedia software, wav is often used in large numbers for event sound effects and background music. PCM encoded wav can achieve the best sound quality with the same sample rate and sample size, so it is also widely used in audio editing, non-linear editing and other fields.
Features: The sound quality is very good and it is supported by a lot of software.
Suitable for: multimedia development, saving music and sound effects.

OGG encoding

ogg

An audio codec called Ogg Vorbis appeared on the Internet, known as the MP3 killer! What is the origin of Ogg Vorbis? OGG is the project name of a large multimedia development program, which will involve the development of video and audio encoding. The whole purpose of the OGG project plan is to provide a completely free media encoding solution for anyone! OGG’s belief is: OPEN! FREE! The word Vorbis is the name of a “playboy” character in the fantasy novel “Small Gods” by Terry Platjat. This term became the official name for audio encoding in the OGG project. At present, Vorbis has been successfully developed and an encoder has been developed.
Ogg Vorbis is a high quality audio coding scheme. Official data shows that Ogg Vorbis can achieve better sound quality than MP3 at relatively low data rates. Ogg Vorbis is also much more advanced than MP3, which was successfully developed in the 1990s. It can support multiple channels, what does this mean? This means that Ogg Vorbis can encode all channels with the support of SACD, DTSCD, DVD AUDIO ripping software (currently there is no such software), instead of MP3 it can only encode 2 channels. The rise of multi-channel music has brought revolutionary changes in music appreciation, especially when enjoying the symphony, it will bring more presence. This revolutionary change cannot be adapted to MP3.
Like MP3, Ogg Vorbis is a flexible and open audio codec that allows for significant sound quality adjustments and further algorithm improvements once the codec has been fixed. Therefore, your sound quality will get better and better. Like MP3, Ogg Vorbis is more like an audio coding framework, which can be continually improved by introducing new technologies. Like MP3, OGG also supports VBR.
MPC encoding
MPC is another impressive and powerful player. Its popularization process is very discreet and there is no complicated backstory. She only has one purpose for her looks, smaller size and better sound quality! MPC was previously known as MP+, and it’s obvious who it’s targeting. However, anyone who has used this code will be impressed by its excellent sound quality.
mp3PRO encoding
On June 14, 2001, Thomson Multimedia SA and Fraunhofer Institute released a new version of music format on June 14 named mp3PRO, which is an improved scheme based on mp3 encoding technology is quite attractive in features announced by the officer. According to various information, mp3PRO is not a completely new format, it is an improvement based on traditional mp3 encoding technology, and its biggest technical feature is SBR (Spectral Band Replication), which is a new audio encoding enhancement algorithm. Provides the ability to improve speech and audio encoding performance at low bit rates. This approach increases audio bandwidth or improves encoding efficiency at a specific bit rate. The biggest advantage of SBR is that it can achieve very efficient encoding at low data rates. Unlike traditional encoding technology, SBR is more like a post-processing technology, so the quality of the decoder algorithm directly affects the sound quality. . The high frequency is actually produced by the decoder (player), and the SBR encoded data is more like a set of commands that produces high frequency, or a guide signal source, which is kind of the way it works. We can see that mp3PRO is actually a mixed data stream encoding of mp3 signal stream and SBR signal stream. Relevant information shows that SBR technology can improve high-frequency sound quality with little data traffic by about 30%. We don’t care how this 30% is obtained, but it can be predicted in advance that this improvement can make the 64kbps mp3 reach 128kbps. The sound quality level of mp3 (note: under the same encoding conditions, the increase in data rate is not proportional to the increase in sound quality, at least in the human ear), which is comparable to mp3 PRO official 64kbps, which is comparable to 128kbps mp3 The propaganda is basically consistent.
