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! Key features: • 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.}

I tripped over this creation by accident, what a beautiful piece of work. Simple to use with seemingly infinite sound generational potential. I like having an on board record facility - simply copy and paste wherever you want without having to open DAWs and the like, recording on a whim is great. I love this.

This app has a very cool concept. However, some things should be improved in an update. - The default pitch is way to low. The first harmonic sould be 55 hz. - The lower harmonics are way to dark. All of them should be like last harmonics. - It would be cool if you could zoom in on certain harmonics since it's hard to be precise. - may be all these things can already be changed, I don't know. These is no Voice over support.

Really like this one. Can produce sounds that I can use as spice in different projects. Great with export to wav function as well.

This synth could be used on an Aphex Twin record, and then used happily by kindergarteners for hours. If you need source sound for virtually ANY purpose, snap this sucker right up. Sometimes when I’m “making music,” I come to a point where I’m just aimlessly pressing buttons, turning knobs sifting through sample libraries. If i put SpectrumGen in front of me, suddenly my nothing is given purpose. This developer has impressed the heck out of me and I have most of their apps, have not been let down yet. Thank you!
