 // Note about empirical tuning:
 // The maximum FFT size affects reverb performance and accuracy.
 // If the reverb is single-threaded and processes entirely in the real-time audio thread,
 // it's important not to make this too high.  In this case 8192 is a good value.
 // But, the Reverb object is multi-threaded, so we want this as high as possible without losing too much accuracy.
 // Very large FFTs will have worse phase errors. Given these constraints 32768 is a good compromise.
