MatcherCL
Copyright (c) 2014 Sergeev Kirill deLuther Tech.

The MatcherCL software is provided free of charge without warranty of any kind.
Usage: 
Run MatcherCL.exe and follow dialog prompts, SOURCE is file to match to TARGET file average spectrum.
Optionaly convolved SOURCE can be saved, if you don`t need it - just press Cancel in dialog.
Impulse length set to 150 ms internally which gives acceptable low end response and artificial reverberation.

To properly use impulse better to turn off auto gains in convolution plugins 
and set gain to 0 db (unity).

MatcherCL.exe can be used as standalone offline convolver, just add -c to the command:
MatcherCL.exe -c
(can be done in shortcut to application)
Optionaly, processing block size can be specified (default is 256), for example:
MatcherCL.exe -c 128

For testing purposes pulse signal (with default length of 150 ms) can be generated:
MatcherCL.exe -pi
Optionally, sample rate can be specified as:
MatcherCL.exe -pi 96000
Default is 44100.

One of convolution quality tests is convolve some source with pulse impulse and compare result with initial file,
ideally, there should not be difference.

This software uses following libraries: 
libtsp (http://www-mmsp.ece.mcgill.ca/Documents/Software/Packages/libtsp/libtsp.html) 
for audio files handling and Bessel function,
Eigen (http://eigen.tuxfamily.org/) for container classes
and Ooura FFT (http://www.kurims.kyoto-u.ac.jp/~ooura/index.html) for Fourier transforms.
