Should be noted, this app Requires Photoshop, OR other advanced image editor (?) for Full functionality (instrument isolation, etc.). I used Photoshop. The UI is nice, but could use some work (i.e. tooltips). I couldn't get the knobs to change appearance, the setting seemed to be ignored, even on relaunch. The program crashed on me twice within the space of an hour, doing different things. I tried a bunch of what was showed on the demo videos. It takes some time to do some of the advanced stuff (instrument isolation in photoshop...).
I found it very fun running images into it actually. It didn't get a canon .cr2 file, though, I had to convert it to jpeg first. The documentation has numerous typos and could elaborate on image formats for importation, and there are other items that could certainly use some clarification (which I did figure out eventually).
The program seems to do two principle things convert images into sound (and also to sound-image files), and convert sound files (mp3, etc.) into image files that are then editable. I think they called this image-of-sound a spectrograph (?).
For the Non-commercial license at $60, I could see a non-pro customer base (which could make use of improved documentation). Overall, it was a fun app, unfortunately, my workflow for potential usage takes a little more time than I can dedicate to a new computer function. I could see however JUST using it for translating images into sound, which would be very quick by itself... but there are so many tempting features (a good thing) it would be hard to stop there. For me, it's a Wish I Could (dedicate my time to) app. I'm sure there are plenty out there that would love it.
