= Proposed roadmap for Musepack =

== 1. Code cleanup and restructuring ==
 a. Split mppenc into 4 parts :[[br]] no nead to be able to compile mppenc, but libs must compile and have clear entry points and structs
  * libmpcpsy for the psycoacoustic model
  * libmpcenc for pqf filtering, quantization, entropy coding and stream formatting
  * libreplaygain for replay gain calculation
  * mppenc (name: mpcenc) for command line utility
 b. Make a minimal mppenc using libmpcenc, lipmpcpsy and .wav input (using libwavformat). Encoding must be the same as 1.15w bit for bit (without tags).
 c. Code cleanup :
  * rewrite mppenc from old code and use libs as much as possible (taglib, ...)
  * code cleanup : remove all unused / commented code, look for duplicated code, use faster fft lib for libmpcpsy (must be under LGPL, BSD or similar license)

== 2. First sv8 steps ==
 * define sv8 needs
 * write bitstream and decoding specs for sv8
 * add sv8 to libmpcenc / libmpcdec
 * create a utility to convert sv7 => sv8 using libmpcdec / libmpcenc
 * maybe release sv8.0 at this point
 * mux sv8 frames into other containers (mka, mp4, nut)
 * try to improve entropy coding of current stream. release sv8.1 if successful, update the convert utility

== 3. Improving sv8, the incompatible way ==
untill this point, conversion from from sv7 to sv8 was lossless.
 * Improve lipmpcpsy if possible (doesn't break compatibility, but makes old encodes obsolete)
 * Change core compression : attempt to make good use of new transform compression tools. This time compatibility is totaly broken. Once done release sv8.2 ?
