Performance Considerations
The default Pd audio buffer
settings for both I/O vector size and signal vector size will work fine
for FFT sizes up to around 4096 or so. For larger FFT sizes, adjusting
the Pd signal vector size and I/O vector size upward can dramatically
improve performance. With larger FFT sizes, the reported CPU load may
fluctuate. This is because a large FFT is being performed only once for
several vectors worth of samples. The default FFT size is 1024, and the
default overlap factor is 8. The maximum FFT size is 1073741824. Let me
know if you find a computer powerful enough to compute the maximum FFT
size in real-time.
