Overtone Analyzer Quickstart Tutorial: record and visualize your voice


Published on Mar 10, 2013
This is a video version of the quickstart tutorial for Overtone Analyzer that can be found at The video explains the basic features of the software and how to use them to record and visualize your voice or instrument.

In particular, I’m showing you to set up your microphone, how to make a recording, how to play it back and listen to it, how to visualize the fundamental pitch, the spectrum, and the spectrogram, how to apply frequency filters to listen to individual overtones, and how to use the overtone sliders.

Normalized Spectrum for easy comparison of relative harmonic intensity in Overtone Analyzer


Published on Apr 11, 2013
This video shows how to compare the relative intensity of the harmonics in a recording with the new normalized spectral display in Overtone Analyzer. Instead of showing the absolute intensity in the spectrum, each point in time is scaled so that the loudest harmonic at that point has zero decibel, and the intensity of all other harmonics is relative to the loudest one. This makes it easier to visualize the spectral composition and the timbre of the sound.

The overtone singing is done by Wolfgang Saus (, and the software is Overtone Analyzer (
