Export a Gesture Synth Loop as WAV

Create at Least One Loop Event

Set the BPM, number of bars and time signature before recording. Select a track, choose Record and wait through the one-measure count-in. Recognized chord or Theremin events are quantized to the visible steps until the loop wraps.

You can also edit the grid directly. Add a degree to an empty step, clear a mistaken event or use another track for a second layer. The export length follows the current bars, signature and tempo rather than the amount of time you kept the camera running.

• Confirm at least one coloured event appears in the grid.
• Use a slow BPM while learning stable camera gestures.
• Add separate layers on Tracks 2–4 instead of overwriting Track 1.
• Listen through one full loop before downloading.

Check Track Volume, Mute and Solo Before Export

The offline renderer respects each track's volume, mute and solo state. If any track is soloed, non-solo tracks are excluded. Muted tracks are excluded even when their grid events remain visible. Review these controls before assuming an event is missing from the file.

The exported sound also preserves whether each event came from Gesture or Theremin mode and applies the saved filter position. Master playback from the live camera is not captured; only the sequencer data becomes the downloaded audio.

What the Downloaded WAV Contains

Supported browsers render a two-channel file at 44.1 kHz and encode it as 16-bit PCM WAV. The default filename is gesturesynth-loop.wav. A limiter is applied during rendering to reduce clipping when multiple tracks play together, but track balance should still be checked by ear.

The file contains synthesized oscillators generated from loop events. It contains no webcam frames, microphone recording, account information or cloud project data. The loop editor itself is session-based, so download the file before reloading or closing the tab.

Make a reference export before arranging several tracks. Set one bar of 4/4 at 60 BPM, place a single basic chord on the first step and leave the remaining steps unchanged. With no tracks soloed and the active track unmuted, the rendered loop should last about four seconds because four quarter-note beats at 60 BPM each take one second. Open the downloaded file in an ordinary audio player and confirm that the chord begins, decays and the file reaches the expected loop boundary. This small known case checks timing, file decoding and output level. If it works but a later arrangement is silent, compare the later track mute, solo, volume and grid states instead of blaming the export format.

Use the WebM Fallback or Fix an Empty Export

If OfflineAudioContext is unavailable or fails, GestureSynth attempts a MediaRecorder WebM audio export. The interface reports which format was saved. A browser that supports neither path can still play the instrument but cannot create the local download.

For an empty or silent result, confirm the grid contains events, no required track is muted, the expected solo state is active and track volume is above zero. Then try a short one-bar loop in recent Chrome or Edge to separate project settings from browser export support.
