Removing clicks from Sinewaves / Sub
I've often seen questions online about getting rid of clicks at the start of Sine waves / Sub bass. I've seen people talk about the attack and release on the ADSR envelope and other things to try.
Simply using a Lo-pass filter or removing the high band with EQ will remove the click.
the Sine Wave retains the Sub you want but the filter removes the click sound at the start of the notes.
