Move demixing matrix defines to opus_define to better determine availability of Projection API. Allows libopusenc, opusfile and opus-tools to much more easily determine availability of Projection API. Cheers, Drew -------------- next part -------------- An HTML attachment was scrubbed...

Hi! I have some MP3 audio material which is basically speech with some background noises, essentially > 120Hz and < 5kHz. I had the idea to reduce the file size by recoding the material to Opus at 56kbps. Unfortunately the result is a file sampled at 48kHz much larger than the original. I hope you agree that it does not make sense to create a file larger than the original (MP3). Of course

I have an audio device whose 'driver' gives me Opus encoded frames using OPUS_APPLICATION_AUDIO and max bandwidth set to OPUS_BANDWIDTH_NARROWBAND. How does Opus encoder decide the center point of the 4K bandpass filter? Is it done frame by frame? -- Tony -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Ulrich, I assume you've been using opusenc to encode the files. If that is the case you can try giving the encoder some more hints about your files: opusenc --speech --set-ctl-int 4008=1103 ... The latter should tell the encoder that the signal bandwidth is 8kHz (OPUS_SET_BANDWIDTH). See opus_defines.h for all valid numbers. You can also experiment with the complexity settings.  -Mathias

Hi, Optimizes celt_pitch_xcorr for ARM NEON floating point. Changes from RFCv3: - celt_neon_intr.c - removed warnings due to not having constant pointers - Put simpler loop to take care of corner cases. Unrolling using intrinsics was not really mapping well to what was done in celt_pitch_xcorr_arm.s - Makefile.am Removed explicit -O3 optimization - test_unit_mathops.c,
