Notes:

Background: Musepack is an open souce lossy audio compression. It is optimized for "transparent" audio coding at ~180 kbit/s and higher. Is is loosely based on MPEG audio layer II but adds several improvements, while avoiding some of the compression artifacts that is present with MPEG layer III (.MP3) even at high bit-rates. For more info, see http://musepack.net/.
Stream versions: Both SV7 and SV8 type files can be read, but only the newer SV8 is written.
Meta info: Metadata is written in APE-tag format (it can also be read from ID3v1 and ID3v2 format).

Features:

32-bit floating point data, mono / stereo, 32 / 37.8 / 44.1 / 48 kHz, bit-rates from ~20-350 kbit/s, text info, image.
