Description
The SHN file format, short for Shorten Compressed Audio File, is a type of compressed audio file developed for efficiently archiving high-quality digital audio. Shorten was one of the early lossless compression methods for audio, meaning it allows the exact original audio data to be reconstructed from the compressed data, without any loss in quality.
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.
