What are the common audio formats?
Most frequent and popular sound formats
05 AAC format
AAC is actually short for Advanced Audio Coding. The algorithm adopted by AAC is different from that of MP3. AAC improves encoding efficiency by combining other features. The AAC audio algorithm far surpasses some previous compression algorithms (such as MP3, etc.) in terms of compression capabilities. In conclusion, AAC can provide better sound quality with 30% smaller file size than MP3 files.
It is one of the best lossy formats out there. There are multiple encodings, with bit rates up to 448 kbps. In terms of hardware support, advanced mobile phones and mp3 players are now generally supported.
06 VQF format
The VQF format is an audio compression technology jointly developed by YAMAHA and NTT. Its compression ratio can reach 1:18. Therefore, under the same circumstances, the compressed VQF file size is 30%-50% smaller than MP3, which is more suitable for online streaming, while the sound quality is excellent, near to CD quality (16-bit, 44.1 kHz stereo). But VQF has not revealed the technical standards, so far it has not become popular.
07 FLAC format
FLAC is short for Free Lossless Audio Codec, which can be interpreted as Chinese lossless audio compression coding, which is characterized by lossless compression. Unlike other lossy compression codes like MP3 and AAC, it can restore the sound quality of music discs. It is now compatible with many software and hardware audio products.
It can be said that FLAC is similar to MP3, but it is losslessly compressed, which means that the audio is compressed in FLAC without losing any information. And you can use the player to play compressed FLAC files, just like playing MP3 files.
08 APE format
APE is one of the most popular digital music file formats. Unlike lossy compression methods like MP3, APE is a lossless audio compression technology, which means that after compressing the audio data file read from the audio CD in APE format, you can also compress the file in APE format. The audio file is exactly the same as before compression, without any loss.
The file size of APE is about half that of CD, which is loved by many music lovers, especially for friends who want to stream audio CDs over the network, APE can help them save a lot of resources.
