Spatial Audio
Create a simple headphone spatial mix from your audio files. Position sources around a fixed listener, animate their movement and direction with keyframes, and choose a room preset. Render a preview and download the stereo WAV without uploading your files.Read more ↓Show less ↑

Frequently asked questions
How do I animate an audio source in 2D?
Add an audio file and select its numbered source. Drag it in the room or use the position controls. Set the time, then move or rotate the source to create a keyframe. Motion interpolates between keyframes. The listener stays in the center facing the top of the room. All sources start together at zero; render again after changing the mix.
What do direction and room presets change?
Each source is directional: rotating its cone changes how strongly it faces the listener. Direction zero faces the top of the room. Distance affects level, and headphone HRTF panning provides left/right and front/back cues. Room presets add creative reverb; they are not physical acoustic simulations. Headphones give the clearest spatial impression.
Is the export Dolby Atmos or a surround file?
No. This tool renders a two-channel, 44.1 kHz, 16-bit PCM WAV for headphones. It does not export Dolby Atmos objects, ambisonics or multichannel surround. Sources are downmixed to mono before spatialization; existing stereo width is not preserved. Use up to six files, two minutes per file, 30 MB each and 100 MB total, with up to 50 keyframes per source. Reverb tails are included and output peaks are reduced if needed to avoid clipping.
