Hello All,

I recently completed the porting of Opus Encoder on a Cortex M4 embedded
controller. The decoder is yet to be done. Based on the chat discussion I
would be putting CPU performance numbers for

Encoder: Speech, 16KHz, 16-bit mono channel for the following combinations

Complexity: 0,1,3,5,9 and Frame Size of 20 and 40ms for Output bit rate of
4Kbps and 8Kbps

Any suggestions/critical feedback is most welcome....

Happy new year to all.
