From the developer:
Delta Audio Studio is a simple application for modifying the audio. Its potential resides in playing with channels as well as with two different audios at the same time, allowing the user to mix them and create new audio/songs. The tool supports resampling audio, equalizing the channels, and applying audio effects.
You may want to check out more software for Mac, such as Audio Studio Manager, Audio Studio Manager Lite or iSkysoft DVD Studio Pack, which might be similar to Delta Audio Studio.
