Apple's Accelerate framework support #25
Comments

Sorry, missed this comment. I think most (if not all) of it is here: |
@romanbsd do you have any benchmarks? |
No, don't have it handy, was too long ago. But it was at least 4x faster as far as I remember. Also I recall that there were places where I tried rewriting in order to use accelerated functions, and it wasn't worth it, so if you see places that are possible candidates - chances are that I already tried |
Thanks I'll try and take a look, sorry this got missed (this github project is just a mirror of https://gitlab.xiph.org/xiph/speexdsp so PRs sent here can get overlooked). |
Note that this is production quality code. It runs in production on iOS app for some years now. I also ported parts of Accelerate framework to Android (repo vdsp in my account) |
P.S. The changes are in the mdf.c and filterbank.c |
I ported all of the CPU intensive parts of the echo cancellation and preprocess to use the Apple's Accelerate framework. If it's of any interest, I can prepare and submit a PR.
