We are using the Ooura FFT in a few places: - AGC - Transient suppression - Noise suppression The optimized OpenMAX DL FFT is considerably faster, but currently does not compile everywhere, notably on iOS. This change will allow us to use Openmax when possible and otherwise fall back to Ooura. (Unfortunately, noise suppression won't be able to take advantage of it since it's not C++. Upgrade time?)
