Stable with Many Features
I have been using Sound Studio to edit podcasts since version 3.0 was released. It is very stable, and it has many useful and effective filters. I use the filters mainly for cleaning up bad-quality podcasts. The compressor filter is especially useful for podcasts with widely varying sound levels. I have also used the app for recordings and it has no problem recording for over 3 hours, creating a 2GB .aif file.
