Hi, When I use the encode tool with the -vbr switch OR the -cvbr switch I do not see any change in the file size. There is no difference in file size between the above 2 options when I specify a bitrate using the -bitrate option either. My question is when I enter a bitrate it does a good job of meeting my request, so what is the purpose of the -cvbr swit...

Hi, I have found differences in quality between opus_demo and opusenc/opusdec. I used for both applications the same raw pcm file,16 bit,48khz,litle endian. i use libopus 1.1-beta and opus-tools-0.1.7. The command for opus_demo is: opus_demo audio 48000 1 64000 -cvbr -framesize 10 in.pcm out.pcm For opusenc/dec: opusenc --raw --raw-chan 1 bitrate 64 -cvbr --framesize 10 in.pcm in.opus opusdec in.opus out.pcm the PEAQ value for opus_demo is -0.152 and for opus-tools is -0.449 Should I expect the same quality or are opus_demo and opusenc/dec different by def...

I suspect the main difference is due to time alignment of the samples and the exact trimming at the beginning and at the end of the encoded files. I also note that there's a missing "--" in front of "bitrate" and only one "-" instead of two for cvbr in your opusenc command line. Make sure both are also linked to the same libopus (opusenc could be using the system libopus 1.0.x while opus_demo is from git). In the end, the quality should be almost the same, but the files won't be identical due to minor differences in the way the first and l...

Hi There, I have two OPUS handset clients say A & B A is 8 KHz, 12.2kbps cvbr supported OPUS client B is 8 KHz, 16kbps cvbr supported OPUS client When i try to encode a same voice frame(20ms sample frame) at different time intervals(not parallel encoding) for both A & B using same encoder handle by changing only bit rate. Issue here is, some noise is heard for B OPUS...

...loat-api (or define FIXED_POINT and DISABLE_FLOAT_API if you don't use autoconf). The encoder has a bunch of run-time settings that you may want to set, depending on your application. These include bitrate, complexity (probably a low setting for that that chip), and bitrate management (CBR/VBR/CVBR). In the end, aside from the complexity requirements, you should need to do anything special to get Opus running on your chip.

Hello All, I'm looking to try to port a Opus Decoder and Encoder onto the TI CC3220SF (http://www.ti.com/product/CC3220) device. Currently, I have successfully been able to get the decode working for a .ogg file saved locally to the serial flash. My end goal is bidirectional audio using OPUS between two devices. While looking into the documentation for the Encoder, I was not sure what the

Just for fun, I tried to reproduce such an overflow. I turned on all debug macros, assertions, and checked arithmetic and then encoded 2 hours of mixed speech/audio with these parameters: Sample rate = 48000 Channels = 1 Application = OPUS_APPLICATION_AUDIO Bitrate = 24 KB/s Force Mode = MODE_SILK_ONLY Signal Type = OPUS_SIGNAL_AUTO Complexity = 10 Frame size = 480 samples (10ms) No errors came

...arc mentioned, I got a result (maybe problem I'm not sure) that perplexes me, please give me some comments. The result be described as below: First(all init which are needed I have done), I used opus_encode() to get the encoded data successfully. The encoder control parameters are set: VBR=0, CVBR=0, INBAND_FEC=0, and mode is OPUS_AUTO(means I will use CBR), then I can get the individual frames in form of code0 or code3CBR(with padding part). Then, I used opus_repacketizer_cat() to cat 3 of the individual frames(2 code3CBR frame and 1 code0 frame) to become a multiframe successfully. Last,...
