Not a video editor an audio plug-in (AU · VST3 · AAX) for any DAW, for Pro Tools, and for Final Cut Pro, and it loads in any host that supports AU or VST3, including Premiere Pro and DaVinci Resolve. The film on this page just shows what it does to sound.
For film & TV: THALM is sound perspective done from the geometry. The futzing an editor does by hand: EQ and reverb to make a track read as “through the wall,” “down the hall,” “out on the street” happens because you moved the listener, not because you turned knobs. And it gives you the room character of worldizing: the sound of music replayed in a real space and re-recorded, without leaving your timeline.
You don't set filters. You set a place.

The music never changes. Only where the listener is standing does, and the walls between. MOVE THROUGH follows the film. STAY PUT lets you drag the figure yourself.

And the building is yours: name every room and set how each space sounds or start from a blank grid and build the sound environments your scene needs. Even “outside” is editable.

▶ PLAY THE SCENE
How this works
  1. Press play. A scene runs, with music playing somewhere in the building.
  2. Drag the blue figure around the floor plan underneath.
  3. Listen. Walls, floors, distance and doorways all change what reaches you.
