@Joseph-T Audio Cleaner Pro is a Sound Forge variant. Sound Forge doesn't work with Catalina and Big Sur. Only using an older operating system will help or switching to a Windows version.

Thank you, SP. I'll have to consider purchasing a more up to date version!

@Joseph-T Please be aware that there are no versions that will run under Catalina and Big Sur. Development for Mac stopped over a year ago.
