* Use new waveform matching option on ambisonicsexp_waveform_matching3Jean-Marc Valin2019-10-131-0/+4
| | | | Should reduce phase-related problems at low bitrate
* Adds OPUS_{GS}ET_WAVEFORM_MATCHING encoder ctlJean-Marc Valin2019-10-1310-22/+111
| | | | | | | | This option disables psychoacoustic improvements that deliberately alter the waveform (e.g. changing the phase) to improve quality. Although it should never be used for normal mono or stereo recordings, it can be useful for cases where matching the waveform is important, e.g. direct ambisonics (family 2), where the phase changes the spatial location of sounds.
