pub const PROXY_HARMONICS: u32 = 3;Expand description
The amp proxy is the lowest free harmonic up to this one.
A filter that closes moves the high harmonics, not the fundamental. On a generated 110 Hz saw falling 20 dB in 1.15 s under a low-pass that sweeps from 4 kHz down to the fundamental, the fundamental read the fall as 1.091 s, harmonics 1 to 3 summed 1.056 s and the full band 1.033 s.
