Using Mac OS 10.8.2 with Digital Performer 7.24 . . is there any AU software that is similar to Bias 'Soundsoap' that will run on this OS? Soundsoap is incompatible, and Bias is out of business. Everything I've found is either too complicated, too expensive, or requires an i-Lok. I primarily want to remove ambient background noise from vocal recordings. Thanks for any assistance!
