Hi all, I noticed some odd behavior with the Opus encoder, and I was wondering if this is a known issue. First, note that this problem occurs when the Opus encoder is created with OPUS_APPLICATION_VOIP, there is no issue if the encoder is created with OPUS_APPLICATION_AUDIO. If compiled for a 32 bit architecture (i386), the encoder experiences significant slowdowns when regular audio is followed by digital silence. The size of the encoded frames is also far too big: 128 byes for 20ms of pure sile...

....g, 2000 +- 500, or 2000 with occasional dips and peaks, I still do not get a reasonably good visual signal reconstruction. Also, I'm not quite sure if my opus implementation works as it should yet. I can run the encoder with OPUS_APPLICATION_RESTRICTED_LOWDELAY, but If I try to run it with OPUS_APPLICATION_VOIP or OPUS_APPLICATION_AUDIO the opus_encode function returns just 2 (size of encoded samples) and the opus decode just returns 0's. I would imagine to get the best audio reconstruction with OPUS_APPLICATION_AUDIO. What could be the reason for OPUS_APPLICATION_AUDIO not working? Best, Nick ____...

...ation as well. :/ Currently here is how I am setting up my encoder: int size = opus_encoder_get_size(1); sOpusEnc = Memory_alloc(OpusHeap,size,NULL,NULL); // // sOpusEnc = opus_encoder_create(16000, // 1, // OPUS_APPLICATION_VOIP, &i32error); i32error = opus_encoder_init(sOpusEnc, 16000, 1, OPUS_APPLICATION_RESTRICTED_LOWDELAY); opus_encoder_ctl(sOpusEnc, OPUS_SET_BITRATE(16000)); opus_encoder_ctl(sOpusEnc, OPUS_SET_VBR(1)); opus_encoder_ctl(sOpusEnc, OPUS_SET_VBR_CONSTRAINT(0)); opus_encode...

Jean-Marc, Thanks for the response and the helpful info. I am trying to get the library to build without using the pseudostack define, and use either VAR_ARRAYS or ALLOC, but it seems the global stack is not defined. Where do can I define this in my example? VR -----Original Message----- From: Jean-Marc Valin [mailto:jmvalin at jmvalin.ca] Sent: Tuesday, February 20, 2018 5:40 PM To:
