Dear list, I am analyzing multi-pitches of musical tones which are predominated by 5th, 7th, 9th, 11th, and/or 13th harmonics. Multi-pitches of these quasi-periodic complex tones have been transcribed with the help of autocorrelation. However, it seems that stream segregations due to multi-pitches is noticeable, but the perceived pitches are ambiguous. An example of Chinese flute music with multi-pitches is at The transcription is at Small notes above the prominent F0 pitches are determined according to the "streams" in the autocorrelogram. I found that it is difficult to compare the perceived pitches to the musical notes in the transcription. Any suggestions and/or references are much appreciated. Best, Chen-Gia Tsai gia(at)
