...esults 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 file is a properly up-sampled copy of the 8Khz file). When compressing these, the 1...

Hi,? Anyone could provide more information on the level of complexity (OPUS_SET_COMPLEXITY(x) , x between 0 and 10 ?) which is recommended for generic Android devices ? How about the iPhone devices ??Is there a way to choose this complexity level according to the device model ? Any hints ? We've seen they set 5 in webrtc :http://code.google.com/p/webrtc/issues/detail?id=3093Frees...

Hi , I am trying to optimize OPUS codec to TI compiler C64XX in CCS. I have created the make file and compiled the code in optlevel = 3. The MIPS are pretty high(99 MIPS for 8Khz stereo) for LFE channels and the most MIPS intensive function is the silk_noise_shape_quantizer_del_dec() function. 1. I am trying to convert this entire function to assembly. I have tried to incoporate .asm file but I

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:
