Adjustable stereo width
Keep the center focused, narrow the stage, or expand the left and right channels into a broader image.
Convert regular audio into a wider, deeper spatial stereo mix with scene rotation, movement, elevation, and room controls, then export the format you need.
Drop a stereo song, soundtrack, ambience, or recording here, or import from:
Expand and position the stereo scene with adjustable width, depth, height, motion, and room response.
A spatial audio converter reshapes a regular mono or stereo file so the result feels wider, deeper, closer, farther away, or moving around the listener. This browser tool preserves a two-channel stereo output while adding scene width, rotation, elevation, distance, motion, and room cues.
The exported file is designed for ordinary headphones and stereo playback. It is not an object-based Dolby Atmos master, an ADM BWF file, or a replacement for a multichannel Atmos production workflow.
Keep the center focused, narrow the stage, or expand the left and right channels into a broader image.
Move the scene nearer or farther away and introduce vertical positioning for a more dimensional perspective.
Set a fixed orientation or move the complete stereo field in an orbit or side-to-side path.
Blend a spatial room layer with the original signal and keep the output peak under control before export.
Render the spatial stereo result locally and export WAV, MP3, M4A, FLAC, or OGG without uploading the source for processing.
Start with a preset, then fine-tune the scene for the source and destination.
Choose a song, soundtrack, ambience recording, dialogue mix, podcast, or other mono or stereo audio file.
Use Wide Stage, Cinema, Intimate, or Rotating Scene as a practical starting point.
Adjust width, rotation, elevation, distance, spatial mix, room amount, and optional motion speed.
Create the complete stereo result, compare it with the source, then download WAV, MP3, M4A, FLAC, or OGG.
Use scene-level controls when the relationship between the left and right channels should remain part of the result.
Open a narrow mix, create a more intimate stage, or add slow movement for a stylized headphone version.
Give backgrounds, transitions, and cinematic moments a larger perceived space.
Increase width and depth while retaining the stereo relationships captured in the original scene.
Rotate or sweep a complete texture to create motion without editing channel automation by hand.
A convincing result depends on width, depth, room, and motion working together rather than every control being set to maximum.
Extreme width can weaken centered vocals, dialogue, kick, and bass, so compare the processed result with the original.
A distant scene can support more room response, while a close scene usually benefits from a drier setting.
Headphones reveal positional movement clearly, while a speaker check helps confirm that the stereo image remains useful.
These formats and effects can all create a more immersive impression, but they use different controls and serve different listening goals.
| Listening detail | Spatial audio converter | Binaural audio renderer | 8D audio maker |
|---|---|---|---|
| Main goal | Reshape the complete stereo scene | Place a source at a perceived 3D position | Move audio through a repeating stereo orbit |
| Key controls | Width, rotation, depth, elevation, motion, and room | Direction, elevation, distance, motion, and spatial mix | Intensity, orbit time, room, and direction |
| Best source | Mono or stereo music, film audio, ambience, and sound design | Speech, ASMR, game cues, ambience, and point-source effects | Songs, ambience, transitions, and stylized edits |
| Playback | Stereo headphones or speakers | Headphones or earbuds | Headphones or earbuds |
| Output | Two-channel spatialized audio | Two-channel HRTF-rendered audio | Two-channel audio with automated panning |
None of these browser effects creates a Dolby Atmos master or object-based ADM BWF deliverable.
Upload mono or stereo audio, choose a preset such as Wide Stage, Cinema, Intimate, or Rotating Scene, then adjust width, rotation, elevation, distance, motion, spatial mix, and room response. Render locally, compare with the source, and export the finished stereo file.
Binaural Audio places a source at a perceived point around a headphone listener. Spatial Audio keeps the source's stereo scene and shapes its width, orientation, depth, elevation, motion, and room response.
No. The result is a two-channel spatialized audio file, not an object-based Dolby Atmos master or an ADM BWF delivery file.
Headphones make rotation, elevation, and motion easier to hear, but the stereo width and room changes can also work over speakers. Always check both when the result will be shared widely.
Yes. A mono source can be positioned spatially, although a stereo source provides more scene information for the width control.
Choose WAV, MP3, M4A, FLAC, or OGG. WAV and FLAC suit higher-fidelity workflows, while MP3, M4A, and OGG are useful when smaller files or broad playback compatibility matter.
Not in this workflow. The tool creates a two-channel stereo result with spatial cues. Traditional surround formats use multiple speaker channels, while object-based systems such as Dolby Atmos also store positional metadata.
