If I wanted to maximize the update speed of a FFT, is it feasible to use a 128 point FFT at 90% overlap? I understand that there will be very bad frequency resolution, but I am just wondering if it would be possible to run in real time, and if I would have to code it manually or if it is already supported in the audio library.
Also, if someone could double check my math... at a 44.1khz sampling rate, with a 128 point FFT, and a 90% overlap, the update speed should be (44,100/128) * 10, which is about 3445 updates per second.
