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.
A WAV file is an audio file that uses a standard digital audio file format utilized for storing waveform data. It allows audio recordings to be saved with different sampling rates and bitrates and is often saved in a 44.1 KHz, 16-bit, stereo format, which is the standard format used for CD audio.
