@ -64,7 +64,7 @@ ARGUMENT:: fftSize
The inner FFT/IFFT size. It should be at least 4 samples long, at least the size of the window, and a power of 2. Making it larger allows an oversampling of the spectral precision.
RETURNS::
An array of three audio streams: [0] is the harmonic part extracted, [1] is the percussive part extracted, [2] is the rest. The latency between the input and the output is TBC samples.
An array of three audio streams: [0] is the harmonic part extracted, [1] is the percussive part extracted, [2] is the rest. The latency between the input and the output is ((harmFiltSize + (winSize / hopSize) - 1) * hopSize) samples.
