| File extension | .MP3 |
| Category | Audio File |
| Description | MP3 is the most popular audio file type based on MPEG-1 Layer III compression. Its lossy algorithm was developed in 1991. MP3 codes the sound almost with the same quality, as CD (16-bit stereo), providing compression in size 1 to 10 from the original WAF or AIFF tracks. The quality of MP3 seriously depends on the bitrate. It can be 128 - 256 kbps. Higher bitrates are also supported, but they seriously increase the file size. It is supported by all modern hard- and software players. |
