correct
fun correctBoundaryOctaves(pitchesHz: FloatArray, hopMs: Int = 10, boundaryWindowMs: Float = 50.0f): FloatArray
Correct octave errors at phrase boundaries (onset/offset).
YIN sometimes detects the wrong octave at the start or end of a phrase where the signal is weaker. This corrects by comparing boundary regions to the stable interior of each phrase.
Return
Corrected pitch array
Parameters
pitches
Input pitch array in Hz (-1 for unvoiced)
hop
Hop size between frames in milliseconds (default: 10)
boundary
How much of phrase edges to check (default: 50)
