2019-09-25Use new waveform matching option on ambisonicsexp_waveform_matchingJean-Marc Valin
Should reduce phase-related problems at low bitrate
2019-09-24Adds OPUS_{GS}ET_WAVEFORM_MATCHING encoder ctlJean-Marc Valin
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.

2018-09-27Prevent the SILK counter from overflowing after 2 years and 9 monthsJean-Marc Valin
or "just" 1 year and 4 months for 10-ms frames. The overflow can eventually cause a divide-by-zero when counter == -16 Thanks to Dmitry Malinin for reporting the bug.

2018-09-14Fixes packet parsing for 16-bit CPUsv1.3-rc2Jean-Marc Valin
Without that change, a very long (> 682 ms) illegal packet could trigger a wrap-around in the test and be accepted as valid. Only 16-bit architectures (e.g. TI C5x) were affected.
