This file is saved in a binary format, which requires a specific program to read its contents.


Compressed audio file similar to a .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.

More Information
