==== Description: ====
This program takes a sound stream as its input and convolves it with a filter
specified at the commandline, writing the result to standard output. It
supports arbitrary samplerate input, resampling the provided filter. An
arbitrary number of input channels is mapped onto an arbitrary number of
output channels depending on the number of channels in the filter file, one
for each input->output channel combination. Gain and a simple limiter are
controlled via the commandline.

This can be used to apply finite impulse response filters, such as recorded
reverb impulses or head-related transfer functions (to create "3D sound"), to
the input file. Since FFTs are used for convolution, this can be done in
real-time, even with large filters (>2s).

Also included is a script used to generate impulse responses, and, as a
reference, my personal home-recorded HRTFs.
