smooth phase offset subtraction like Props Subtractor
Hi,
I guess I need to do something with sah~ to get tweaking the phase smooth.
I would avoid sah~ for this as it would require feedback and hence a vector of delay from a send~receive~ pair.
Something like this is simpler, and will sound smoother than doing it with sah~, because it will let you control the phase offset at audio rate.
Also, if this is for a synth, consider using saw~ instead of phasor~ as it is already band-limited, so will sound better (less aliasing). And to spice things up, you could try adding a tiny amount of band-limited noise to the oscillator frequency and the phase offset, to keep the phase interaction of the sum moving constantly, which you might like……..perhaps a little more "analogue-esq" if you get the scaling right ;) Also, because you’re subtracting the two oscillators, you need to limit the phase offset so it never reaches exactly 1, or you’ll get no signal.
You might want to add the phase offset to the sum of the oscillators, to remove the DC-offset it creates. Also, I just noticed that what you’re creating is essentially pulse-width modulation of a square wave. You can do it more easily with train~. If you then do want the DC-offset back, just subtract the phase-offset from the output of train.
