Web Audio Synthesizer — Subtractive Synth, Oscilloscope & ADSR

Play a real subtractive synthesizer built on the Web Audio API — two oscillators, an ADSR envelope, a filter, and a live oscilloscope showing the actual waveform you are generating — genuine audio synthesis, not a sample player, exportable as standalone HTML.

How to use Aether Audio Synth & DSP Studio

1. Play notes and adjust oscillator waveforms.
2. Shape the sound with the ADSR envelope and filter.
3. Watch the live oscilloscope.
4. Export as standalone HTML if you want to embed it elsewhere.

Frequently asked questions

Is this generating real audio synthesis, or playing samples?

Real subtractive synthesis via the Web Audio API — oscillators generate actual waveforms shaped by the filter and envelope, not pre-recorded samples being played back.

What does ADSR stand for?

Attack, Decay, Sustain, Release — the four-stage envelope that shapes how a note's volume changes over time from the moment it is played to when it fades out.

Can I export what I build?

Yes — a standalone HTML export lets you embed the synthesizer configuration elsewhere.
