       jconv  -  is  a Convolution Engine for JACK using FFT-based partitioned
       convolution with multiple partition sizes.

       This manual page documents briefly the jconv program.

       jconv is a Convolution Engine for JACK, based on FFT convolution  using
       the  convolution  engine for reverberation processing. This distributes
       the calculation over up to five threads, one for each  partition  size,
       running  at  priorities  just  below  the  the one of JACK’s processing

       To run this program you need config file and wav file for  convolution.
       Demo  config  files  you can find in /usr/share/jack-jconv/config-files
       (You have to edit path to your convolution wav file)
       Set of wav files you can download  from  Fons  Adriaensen’s  web  pages      (jconv-
       reverbs.tar.bz2) or you can use another  convolution  files  which  are
       supported by libsndfile.

       Some  other  info  can  be  found in README and README.COFNFIG files in


       A summary of options is included below.

       -h     Display short help

       -v     Print partition list to stdout [off]

       -L <nframes>
              Try to compensate <nframes> latency

       -M     Use the FFTW_MEASURE option [off]

       -N <name>
              Name to use as JACK client [jconv]
