[opus] Compexity vs Quality

[Hoene]

We will make same soon (Feb). 

I would be happy to understand how you did your perform measurement and
which parameters you used.

Betreff: [opus] Compexity vs Quality

 

Hi,

 

The complexity settings in Opus affects the CPU load a lot, below are some
preliminary figures (MIPS) we got on Samsung Galaxy S2 1.2 (1.2 GHz ARM7)

 

8KHz codec encode/decode - OPUS/8000 C0        56.51

8KHz codec encode/decode - OPUS/8000 C5        106.06

8KHz codec encode/decode - OPUS/8000 C10       156.55

16KHz codec encode/decode - OPUS/16000 C0       99.19

16KHz codec encode/decode - OPUS/16000 C5       196.00

16KHz codec encode/decode - OPUS/16000 C10     293.12

 

My question is if anybody have “real” testing on how complexity setting
impact speech quality?
