After the long time of preparations, discussions and realization of the test the results are finally here.

I found the first and the last graphs to be particularly informative.
From first graph it's easy to see that half of AAC encoders did excellent on male English speech (Sample 18). The same is valid for female English speech (Sample 06). Then it's correct to say that modern high quality AAC encoders perform very well on speech at 96-100 kbps. I think we missed a category of sample as "speech with some background sounds". It's different from song with voice (Sample 17). Though I haven't seen such samples among repositories with testing samples. |
