spectmorph-0.0.3 has been released. The main improvement is that the piano
samples sound a lot better now, because the attack is modelled better by
the SpectMorph model.

Overview of Changes in spectmorph-0.0.3:
* added encoder algorithm to find attack envelope, this makes piano sound much
  more realistic
* introduced smwavset tool, which allows managing instruments consisting of
  many samples
  - encoding/decoding a set of samples
  - delta operation for comparing errors of sets of samples
* smextract can now provide an overview of how many bytes in an .sm file can be
  attributed to which fields
* documentation updates
* refactoring, cleanups

What is SpectMorph?
SpectMorph is a free software project which allows to analyze samples of
musical instruments. This should allow constructing hybrid sounds, for instance
a sound between a trumpet and a flute. Also interpolating between two samples
of the same instrument (different attack velocity of a piano) could be

SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3

SpectMorph currently is in the early stages of development, which means that it
is not yet ready to be used by end users.

There are sound examples on the website which demonstrate the sound quality of
the current SpectMorph models using piano samples.
