Analog Synthesizer

Twist virtual knobs, shape oscillator waveforms, carve frequencies with a resonant filter, and sculpt attack and release curves until a patch sounds exactly right. Analog Synthesizer puts a full signal chain in your browser — two oscillators, an ADSR envelope, filter cutoff and resonance, plus onboard effects — all running in real time through the Web Audio API with no downloads required.

It rewards curiosity. Nudge the filter cutoff while holding a note and you hear the classic sweep. Stack oscillators a few cents apart for a thick, beating unison. Every parameter responds immediately, so experimenting costs nothing and teaches a lot about how synthesis actually works. It's a genuine tool for creative music-making, not a toy demo.

If you want a more structured rhythmic context for your sounds, Pocket Operator pairs well as a drum machine companion. Analog Synthesizer works best on desktop where a full keyboard gives you comfortable note access and both hands free for the controls.
