Hi Rhishi, PQevalaudio is very unreliable and buggy. I have compared to PEAQ and - as a result - now I am not using it anymore.

Hi, I checked the ODG (Objective Difference Grade) scores for a few reference vectors using the PQEvalAudio Tool and found that some of them show ODG scores as high as -3.5 If we look at the range as described in the link below, it looks unacceptable. http://www-mmsp.ece.mcgill.ca/documents/Software/Packages/AFsp/PQevalAudio.html Am I missing something or are these scores valid? Thanks and

Hi, While testing the Opus Decoder we came across the following: If the decoder encounters an 'Invalid Payload Length' the decoding of the stream is stopped. Also, when the decoder encounters 'Range coder state mismatch', the decoding of the stream is stopped. I believe that it should reject the erroneous payload and start decoding the next payload for it to work properly in a

Hi Dean, It should work for 24kec, 34kc and 74kc cores.

Yeah I see the definition, but unlike USE_ALLOCA and VAR_ARRAYS, it has not been used/set anywhere in the code for allocating buffers!

Actually, the code already has an option for using the heap rather than the stack, see NONTHREADSAFE_PSEUDOSTACK in the code. As the name implies, it's not thread-safe though.

Hi, I am new to the Opus community. I intend to optimize Opus encoder/decoder for MIPS and commit the changes to the Opus repository for it be included in Android. Can somebody point me how to go about it? A pointer to a previous mail thread with a similar discussion might help.

Dear Opus family, we have implemented the Opus codec at a Texas Instruments DSP C6418. It is working fine! Does anyone has experience with the configuration of the codec for a speed optimized implementation on that DSP? At the moment, we use the following settings: #define NONTHREADSAFE_PSEUDOSTACK 1 #define FIXED_POINT

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:

Hi Jean-Marc, thank you for that suggestion! It seems that the file "fixed_c6x.h" is not part of the Opus sources, so the compiler cannot find it after enabling the TI_C6X_ASM config option. Maybe it was only part of an early version of the Opus sources? I looked for the file in versions V1.1, V1.1.1, V1.2alpha and V1.3 but did not found it. Do you have an idea, where I can get the

I suggest you try it. I do know that it requires the dsp extensions, but it may work on a 24k. Just change the -march=74kc and see if it works.

Hi all ! I just learned about the Opus codec and would like to try it out on my NRF52 (Cortex-M4) target.   I've been struggling a bit with the "trival_example.c" setup but repeatedly run into "hard fault" crashes when stepping through the code. Firstly; for a "bare bone" configuration, does the following compiler directives make sense ? UDEFS =

The opus code default compiles on -o2 optimization level. I would like to change it to -o3. I have tried doing the changes in makefile.unix . The change is not getting reflected.

Hi everyone, I?m currently trying to use opus on a ST ARM (STM32F407) without any OS (bare metal). The aim of my project is to transmit voice over CAN bus. The main issue I have is that opus fail to allocate memory, the ALLOC macro always return a NULL pointer. I have sure that I have enough free space to allocate buffers. Is there anyone who already try this or have meet this issue ? Thanks
