Description
A Java Object Serialization Stream - a Java program's saved state (often a game save) written with ObjectOutputStream. Filestar reads the objects, class descriptors and field values the stream holds and dumps them as JSON text.
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.
