Hi,
I'm attaching a patch that implements a new OPUS_SET_WAVEFORM_MATCHING()
ctl that attempts to better match the waveform (and preserve the phase),
even at the cost of worse quality on "regular" mono/stereo files. The
setting can be used by ambisonics family 2 (second patch) to avoid
artifacts caused by phase errors (which matters a lot more for
ambisonics). Since I don't have an ambisonics setup, I'd be interested
in review/testing before I merge that. If you have such a setup, please
report any improvement/regression.
Cheers,
Jean-Marc
