"A Smarter Way to Find Pitch"


Sevag Hanssian will present "A Smarter Way to Find Pitch" by McLeod and Wyvill (, which presents a practical algorithm for determining the frequency of a sampled sound (e.g. the note being played by a recorded instrument); an interesting aspect is the algorithm also gives a "clarity" metric. Anyone interested in signal processing, computing with audio and music, and so on should enjoy this.

Sevag has done a lot of work on pitch detection, and some of his code related to this paper and others can be found at

Thanks to Evolving Web for hosting us again, for sponsoring food and drinks, and everyone in the group for their patience in waiting for this meetup happening again.
