Layered synthesis
Build a sound from up to four layers of tones and noise. Blend two sources in each layer, then give it its own pitch, volume, filters, stereo position, and effects.
Build sound effects and short melodies, right in your browser. Layer tones and noise, draw how they change over time, and finish with delay and reverb. When it sounds right, export a stereo WAV.
No installation. Just open, play, and experiment.
Build a sound from up to four layers of tones and noise. Blend two sources in each layer, then give it its own pitch, volume, filters, stereo position, and effects.
Draw changes with bars and curves, or shape pitch in the note editor. Keep a value steady or let it move over time. Choose which parameters to keep in view as you work.
Turn a single sound into a phrase with up to 64 steps. Set each note's pitch and velocity, leave room for rests, and find the right pace with tempo and step resolution.
Add echoes, space, or a long trailing wash. Control how much of each layer reaches the shared delay and reverb, then shape the timing, feedback, and decay.
The examples below are compact, embedded versions of Reshape. You can play and edit each one. Here, Ocean Waves shows how envelopes shape a sound over time. Press Play, move the amplitude points to change its rise and fall, and drag the high-cut bars to adjust its brightness.
Turn a single sound into a short phrase. Press Play, click or tap steps to toggle notes, and drag them to change the melody. Use the wheel or ↑/↓ on a focused step to change pitch; hold Shift with either to jump an octave.
This ship's horn is built from four layers. Press Play, then toggle the numbers beside the speaker to hear each layer's part. The pencil's numbers choose the layer to edit. On smaller screens, playback layer controls live under ⋯.
Retro Phone uses the note editor to give a ringtone its pitch pattern. Press Play, then drag across the grid to draw a different pattern. Move notes up or down to change pitch, or extend them sideways to hold a pitch longer.
