BeamformIt is an acoustic
beamforming tool that accepts a variable amount of input channels and
computes an output via a filter&sum beamforming technique.
BeamformIt was originally implemented by Xavier Anguera at ICSI for
participation to the NIST RT05s Meetings evaluation to deal with the
different amounts of microphone channels available in a meeting room.
BeamformIt was then rewritten and improved for the RT06s evaluation and
finally
readjusted and documented for public release.
It was initially focused towards processing the data used in
the RT evaluations but it can now process all sorts of data, leading to
an homogeneous single output (SHP format, 16K, 16bits/sample).
