Some new stuff on
Two new shared libraries:
  zita-resampler-0.1.0

  zita-convolver-0.1.0 
Both C++. Unlike the libcl* series which are my 'personal

toolset' that I assume nobody will want to re-use, the zita

series of libraries will be fully documented.
The resampler already comes with HTML documentation, for

the convolver this is 'under construction'. This release

of zita-convolver is provided mainly as a dependency of 
  jconv-0.2.0
Command line JACK app for real-time fft-based partitioned

convolution with non-uniform partition size. Provides low

or zero delay processing at moderate CPU loads.

Any convolution matrix up to 64 * 64 as long as your CPU(s)

can take it. From the README:
New in this release

-------------------
- The convolution engine has been separated into

  a shared library, libzita-convolver. For more

  information on the internals of the convolution

  engine, see the documentation provided with this

  library.
- A non-real-time, file processing version of jconv,

  called fconv, has been added. It accepts the same

  configuration files. The input can be any file

  readable by libsndfile. The output will be a 24-

  bit WAV or WAVEX (for more than 2 channels).
- Large configurations requiring too much memory

  will fail with an error message rather than just

  crash with a segfault.
- Now uses jack_client_open(), so multiple instances

  can be run even without using the -N

  option.
- Optional use of FFTW_MEASURE.
- Added the mkwavex utility, converts multichannel

  responses stored in separate files to a single

  WAVEX file.
- New config files for some AMB reverbs.
The nicest one of these is York Minster, which

really sounds great.
Enjoy !
