...io 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?

Hi Rhishi, PQevalaudio is very unreliable and buggy. I have compared to PEAQ and - as a result - now I am not using it anymore. With best regards, Christian Hoene Von: opus-bounces at xiph.org [mailto:opus-bounces at xiph.org] Im Auftrag von Rhishikesh Agashe Gesendet: Freitag, 4. Oktober...

...ed on Opus. I believe, Opus is going to be a part of Android in the near future and since Android is meant for Embedded domain, I just thought of raising this issue. I am new to this group, hence if this has already been discussed, please point me to the correct mailing list.

In that case, can you please suggest a reliable tool?

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!

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

...pped. 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 streaming environment. Is this an expected behavior?

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.

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.
