If you're looking for a full featured and free audio editing application, OCENAUDIO has it all, including; an uncluttered user interface (GUI), intuitive workflow, clean vector graphics with sample level zooming and editing, and more.
I was looking for a simple audio editing app- with functionality like Audacity, at a reasonable price point- considering I can use Ableton Live for any sort of intense audio processing,
I found Rogue Amoeba's FISSION and after reading the product page, I purchased it ($29). At this point I want to make a comparison.
FISSION is lacking what I would consider some essential basic DSP functionality - even for an audio editing app at the $29 price point. Now I like Rogue Amoeba, and their Audio Hijack app is nothing but excellence in software. I use it almost daily, and it has saved me more frustration and inconvenience than I can remember! Audio Hijack rocks. Unfortunately, FISSION left me wanting for standard or essential DSP and editing features I expected (e.g. reverse, ability to individually process the L and R channels, EQ, invert, etc.) I could go on, but I digress.
In all, I am totally thrilled to have found OCENAUDIO. In my limited use so far, It's everything I need for quick audio editing and processing work, and even hosts most AU and (after a lengthy scan) VST effects. If you need essential editing and DSP functionality, access to a set of more advanced features, and the ability to expand in the future by using AU and VST effects, OCENAUDIO lets you get the job done, quickly and easily. Did I mention its free? Yup- Now get on it!
