Tracking Live Input Category<br />

Bandpass filter designed to isolate the individual harmonics of its Input. It has quadrature output (i.e. the<br />

left channel output is the cosine part of the Input signal at that frequency; the right channel is the sine part<br />

of the Input at that frequency); thus you can use a QuadratureOscillator to frequency shift this harmonic<br />

using single side band ring modulation.<br />

<strong>The</strong> filter is designed such that, if you were to add together the output of filters set at each harmonic from<br />

0 to the harmonic closest to half the sampling rate, the amplitude of that sum would be 1.<br />

Input<br />

This is the <strong>Sound</strong> that gets filtered.<br />

Fundamental<br />

This is the assumed fundamental frequency. In most cases, you should set it to be the same as the Input<br />

frequency.<br />

Harmonic<br />

This is the number of the harmonic that the filter will try to isolate. In other words, the center frequency of<br />

the filter will be the Fundamental * this Harmonic.<br />
