Hi, I'm working on making an exponential sine sweep (like the patch below) to measure impulse responses. However, when I start it I have an audible 'click' or discontinuity at the beginning of every sweep. I'd rather not introduce any enveloping if possible. My thought was that since cycle~ uses a cosine function, if I pre-set the phase to 0.75 it should make it into a sine and start at 0. But it's still clicking when I start a new sweep. Any thoughts?
