Hi,
We measure the absolute timing of encode/decode for a OPUS mode, this is then
transferred to MIPS using the CPU frequency and MIPS/Hz which comes from
corresponding ARM architecture.
We used default for all OPUS settings apart from complexity settings.
These figures are for the fixed point version, we have tested floating point as
well which had slightly higher figures on same platform.

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?
