This app is AWESOME! I used to have to do this on my desktop, cutting, pasting, and converting files through several pieces of software.
It would be helpful if the app had a few additional features:
1. The option to import an image OR view live sound (the microphone). Right now, it picks up background noise (coughing, cars driving by), which adds unwanted frequencies to the generated sound.
2. The option to output the audio file in different formats (m4a, mp3, WAV). I know different compression algorithms would also change the image, but having a smaller file size would help me email these to myself.
If you could add even more features, it would be even better!
3. The ability to raise or lower the threshold/Hz/limit of the sound so the image could be taller/shorter. Right now some images get stretched strangely.
4. The option to share the output audio file to a different app, rather than only mailing it.
Thank you, again, for creating this!
