My original idea was to visualize one’s control of singing voice – specifically, the subtle frequency fluctuation one may have over time although she/he is trying to hold the pitch.
It was interesting to me because I love human voices, I wanted to look into pitch detection technology, and I’ve never done any visual stuff before.
Here’s a patch I built with Max/MSP using the pitch~ MSP external object made by Tristan Jehan.
All the pitch-tracking is being done inside this patch. Amplitude, Frequency and actual pitch values are being sent to Processing via OSC protocol.
There’re two ways of input – (a). sound files pre-loaded in the select menu (b). Microphone
Yellow: Voice Frequency
Orange: Reference Frequency( 294Hz in this case)
Green: Voice Amplitude
