Ocenaudio

It might not be as feature-packed as Audacity, but Ocenaudio is an excellent free audio editor for podcasters and home musicians.
Making and editing recordings with Ocenaudio is simple, and the software makes frugal use of system resources so even large files won’t cause it to freeze or crash (a problem that’s all too common with free media apps).Ocenaudio comes with a selection of built-in filters, and supports VST plugins so you can add even more. It’s not open source though,
