SpectroBits is a "spectrogram" based synthesizer.

SpectroBits interprets the image as a "Spectrogram": the X-Axis as time and the Y-Axis as frequency (but the MIDI note determines the base-pitch).

The black pixel will be silent and the bright pixels will generate strong harmonics for that freq.

The "A4=440" (red) line means 440Hz if you play the note 'A4'.

The "880" line is 880Hz if you play the note 'A4', and so on.

The pixel colors are interpreted as the pan information. The red pixel for L-ch and green for R-ch. Blue is ignored.

The image can be edited by the right upper "BITMAP EDIT" section. You can also import any images of ".bmp", ".png", ".jpg" and ".gif". Image size is fixed to 512x512. Any images are resized automatically to 512x512 when you import them.
