SpectrumGen is a spectral synthesizer with a minimalistic pixel interface. It's a bit like the PixelWave, but now you can draw the spectrum of sound!
• it is possible to draw the spectrum and play it at the same time;
• export to WAV;
• eight predefined timbres;
• changeable number of octaves (from 2 to 8);
• MIDI keyboard support;
• Audiobus and IAA support.
Dark colors - low frequencies (bass). Bright colors - high frequencies.

Very cool spectrum synth!
Amazing little synth for the price. It's positively bursting with sci fi sounds and sonic possibility. The only thing holding back a five star review is the fact that the low frequencies are represented with the color black--on a black background! You can hardly see what you're drawing / manipulating down there. A more neutral background color could easily fox this. It would be really nice to be able to save patches too.
If only sharing was easier this would be a 5 star.
Experiment with spectral timbre generation
This program gives you a simple, monophonic spectral synth. You can change the spectrum as you play, and multitouch will alternate between your fingers' parameters. Recording the sound will paste it on the Clipboard, where it can be picked up by a number of programs. Its controls are exactly the same as PixelWave's, the main difference being that you are drawing the spectrum instead of the waveform. So: it's pretty simple. Suggestions for the next release: the low frequency end of the spectrum - which is much more important for building up a fundamental in the timbre - should NOT be colored black - it's nearly impossible to see. Some people may want to save out the spectrum and setup as patches - I realize it's difficult in iOS without good document manipulation support. Similarly, some may want to play the wave via MIDI. So, there's room for a more complicated version of this program.
