Awesome, I’ll test this out, particularly with regards to the processing time.

At the moment all the things I’m analyzing (in real-time) (loudness, spectralshape, melbands) come in around 0.3-0.4ms, which I can totally live with. Particularly since I’m shrunk my overall analysis window from 512samples to 256samples. I basically now have around 6ms less latency “for free”.

My `@fftsettings` were the same at the bigger analysis window (I just had more frames for the `fluid.bufstats~`-ing), so will see the impact of speed now.
