2019-02-14Improve silence handlingJean-Marc Valin
Copy the previous analysis data instead of flagging as invalid

logE[b] can end up slightly larger than tonal->highE[b] due to rounding

Thanks to Dmitriy for reporting this.

2018-10-30Remove useless OPUS_SET_EXPERT_FRAME_DURATION() on CELTJean-Marc Valin
frame diration is only handled at the Opus layer. There's no change in behaviour, just less puzzling code. Thanks to Dmitriy <dmilvdv@gmail.com> for reporting this.

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.
2018-09-25Retrain RNN classifier weights to include reverberated speechJean-Marc Valin
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.

2018-09-13Update ISO Base Media Format draft to version 0.8.1.Ralph Giles
- Switch to 'Opus' file type identification. - Revise channel mapping to better support ambisonics.

The error was: c:\projects\opus\celt\celt_encoder.c(1019): fatal error C1001: An internal error has occurred in the compiler. [C:\projects\opus\win32\VS2015\opus.vcxproj] (compiler file 'f:\dd\vctools\compiler\utc\src\p2\main.c', line 255) To work around this problem, try simplifying or changing the program near the locations listed above.

Don't assume that frames larger than 20 ms save any overhead compared to 20 ms.
2018-05-24Fixes a SILK bandwidth switching regressionJean-Marc Valin
The bug was triggered because f982b84d started using prefill for SILK bandwidth changes, which reinitialized the encoder state and prevented the variable lowpass from working properly. To fix the problem, we preserve the sampling rate and variable low-pass when prefilling.
