Hello all, after FOMS I decided to take a look at the opus library and I found that I could improve a bit the build system and cleanup the code a little bit. Most of the changes to the code has been suggested by my two tools cowstats and missingstatic (part of the ruby-elf gem if you care). HTH, Diego

...d format is _exactly_ equivalent to a standard Opus mode, and can even be decoded by a non-custom Opus decoder. However, there is a bunch of analysis that runs in opus_encoder.c that is not enabled for custom modes. A fixed-point standard Opus encoder with OPUS_APPLICATION_RESTRICTED_LOWDELAY, OPUS_BANDWIDTH_FULLBAND, and OPUS_SET_FORCE_CHANNELS should give identical results. In floating point, you will need to call the non-public run_analysis() API and use the CELT_SET_ANALYSIS() encoder ctl to get equivalent results. Using OPUS_APPLICATION_RESTRICTED_LOWDELAY disables SILK and automatic voice/music detec...

I am using libopus for my implementation. I wonder if anybody in the list have any experience on how to make libopus dynamically adjust its bitrate?

..._BANDWIDTH(bandpass)); bandpass is the audio bandpass?, eg: OPUS_BANDWIDTH_WIDEBAND . You will need to calculate the codec bitrate from the available network bitrate (by taking into account the size of the IP+UDP+RTP headers which is 40 bytes ) . By default the audio bandwidth (bandpass) setting is OPUS_BANDWIDTH_FULLBAND , which will utilize more network bandwidth .

Hey, I am having trouble with the size of the encoded bytes by Opus. I am also having issue with the Bandwidth ctl. Here is the scenario. If I encode 16khz sampled audio: opus_encoder_ctl(enc,OPUS_SET_MAX_BANDWIDTH(OPUS_BANDWIDTH_WIDEBAND)) opus_encoder_ctl(enc, OPUS_GET_BANDWIDTH(&x)) = 1102 opus_encoder_ctl(enc, OPUS_GET_MAX_BANDWIDTH(&x)) = 1103 average encoded size = 120 bytes if I
