How to make custom waveforms?
So i wanna try making a sound that starts as a square or triangle wave, then shifts to the other one. I came up with a neat pattern to use as the transformation from one waveform to another, and I'm curious to see how it sounds. The only issue is that I'm very new to Audition and am not sure where to start. Is there a way to make custom waveforms from an image? Maybe from scratch if needed?
This gif is pretty much what I'm aiming to do (each frame of the gif is one cycle of the waveform)
