Audio::calc_real_fft_mixed2mono_outofplace not optimized
Audio::split_l_r not optimized
Audio::calc_real_fft not optimized
Audio::calc_inverse_real_fft not optimized
Audio::combine_l_r not optimized

I saw the above in the log - is this anything to worry about?

No, this is a note to myself that I haven't written NEON code for ARM CPU's yet. Actually.. it might not be such a bad idea to do that now, with all the new ARM programs that we're releasing.

Ah! And there are instructions specifically for what I want to do here! (VZIPQ.32 and VUZPQ.32)

Partially done... 4 gone, 3 to go.
Edit: 6 and 1 now.
Edit: No, 6 and 0. That last one was never used anyway.

Hi Hans, thank you so much for tackling this one. It can never be a bad thing to further optimise the code for the ARM CPUs, particularly as resources aren't as plentiful as you'd find on a more power hungry solution like Intel based PCs and such like.

I look forward to seeing this completed :-)
