The LSP parametric equalizer has an allpass filter. But, what do the controls do in this regard? How does the phase change?
Related to supercollider because i’m using it to process some tracks.
Yeah it doesn’t say how much of a delay it adds, or whether it works in a certain bandwidth or if it’s a fullband allpass. On the gui, the dot handle in the spectroscope moves along the frequency range, but not the gain or the Q. There isn’t much other documentation either.
So the graph indicates how many samples get delayed at which frequency? And k is a scaling term?
What would a Q control do?
