- Description
- Audio format that uses MPEG-1 Layer II compression to reduce the file size; mainly replaced by the ubiquitous .MP3 format, but is still used for digital radio and digital television broadcasts.
- Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
