[opus] STM32 Embedded - memory use and encode problem.

[Andy Wood]

I am using STM32 for encoding and decoding Opus - all works except for...

I am using an 8000Hz sample rate so CELT is never used.

Is there a way to stop it malloc'ing the ram for CELT as on an embedded system it is a bit of a waste, especially as I am using two encoders/decoders.


I have always had a problem with the encode having 'clicking' artifacts - file link attached - this is not the direct PCM but recorded by Audacity off the PC output using a PC  based decoder which I know works OK.

All encoders and decoders are the latest Opus release.

It is recording both discrete channels and the source is BBC Radio 4...

Any suggestions?

Thanks

Andy.
