Nanovoice Game Boy Noise Cartridge

Sixteen channel spectral synthesizer

Description

Nanovoice is a primitive additive synthesizer for the old Game Boy types (DMG). Within a repeatedly playing spectral matrix of 16 time slots and 16 harmonic frequencies, the volume for each pixel can be set in 4 steps. The base/sampling frequency is variable, but only in a very raw resolution which does not match any musical scale. Nanovoice does not play Game Boy specific sounds with the console's built-in synth functions but implements its own synthesis scheme while the soundchip is misused as D/A converter. Digital audio output is realized via amplitude modulation of the Game Boy's two rectangular wave generators, resulting in a 4-bit stereo audio stream with a variable sampling frequency below 4 kHz. Nanovoice sounds best on the original Game Boy (DMG), but also works on Game Boy Pocket, Game Boy Advance and GBA SP. It does not run on Game Boy Color, GB micro and DS.

This particular Nanovoice Gameboy Noise Cartridge is in excellent condition. Includes plastic case.
