- Description
- A raw zlib (RFC 1950) compressed stream: a 0x78 header byte (commonly 78 9C), a deflate body and an Adler-32 checksum at the end. Filestar inflates the stream and then converts whatever the decompressed data turns out to be - often an image or a document.
- 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.
