If you're looking for something else to replace Voice Crush, there are a few tools worth a look that can help you clean up your audio recordings.
Audo Studio is an AI-powered audio cleaning tool that can remove background noise and cut down on echo. It's geared for YouTubers and podcasters, with options like automatic noise removal, echo reduction and volume adjustment.
