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 encode 48khz sampled audio: opus_encoder_ctl(enc, OPUS_SET_BANDWIDTH(OPUS_BANDWIDTH_W...

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:

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?

Hi Kelvin, You can use something like :opus_encoder_ctl(enc,OPUS_SET_BITRATE(bitrate));opus_encoder_ctl(enc,OPUS_SET_MAX_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 4...

...S 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 client, Ex: OpusEncoder* encoder = (OpusEncoder*)encHandle; opus_encoder_ctl(encoder, OPUS_SET_BITRATE(encProp->bitrate)); Is encoder fails to change bitrate to 16kbps even after setting the bit rate using opus_encoder_ctl API? Is there anyway to set bitrate according to requirement for same frame(20ms) encoding? -- Thanks & Regards Vittalprasad B R 8722397247

Hi, I’m wondering how can I get the speech/music classification result when encoding the audio in opus 1.3.1? I found in the file opus_encoder.c, there is a opus_encoder_ctl request as OPUS_GET_VOICE_RATIO_REQUEST, so I wrote in my program the below code: #define OPUS_GET_VOICE_RATIO(x) 11019, __opus_check_int_ptr(x) int32_t voiceRatio; opus_encoder_ctl(encoder, OPUS_GET_VOICE_RATIO(&voiceRatio)); LOGI("voice ratio:%d", voiceRatio); But it always retur...

If you encode with int iByteSizeEncoded = opus_encode(m_enc, m_ShortsInput, (1920/sizeof(short)), m_EncodedBytes, (960*6)); ... the byte size is 120. I thought that an odd value like 359 has to be a fault on my side. I thought it would be a multiple of something. So 359 is really correct??? Thank you for clearing this up.

...TH. I expect that setting this to OPUS_BANDWIDTH_NARROWBAND would give similar results to passing an 8Khz sample rate stream, but OPUS_SET_MAX_BANDWIDTH has almost no effect with any settings. My test data has 4Khz bandwidth. I am testing the opus encoder (latest versions) with the following opus_encoder_ctl options: OPUS_SET_VBR=1, OPUS_SET_VBR_CONSTRAINT=unconstrained, OPUS_SET_COMPLEXITY=10, OPUS_APPLICATION_AUDIO, frame=60ms I compress 2 separate audio streams which only differ in the sample rate. One is 8Khz and the other is 16Khz. Both contain identical 4Khz bandwidth audio (the 16Khz fil...

...independent blocks (say, as an example, 50 frames or 1s each), encode these as raw Opus frames and cache them on disc ahead of time. For each block I'd like to reset the encoder to ensure independence between the first frame of each block and the last frames in the previous block, e.g., using opus_encoder_ctl(enc_ctx, OPUS_RESET_STATE) When the client requests a certain sequence of blocks (which may originate from various input files in (let's pretend) any order) my goal is to (on-demand) encapsulate the pre-encoded frames as WebM and send them to the client. However, in early experiments [2], res...
