AN AUDIO PLUG-IN — AU · VST3
Not a video editor — an audio plug-in (AU · VST3) for any DAW 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.
THALM — the plan view, listener and music placed in the building
STAY PUT — place the music and the listener in the building
THALM — move through, the journey along the timeline
MOVE THROUGH — the journey follows your timeline
AU · VST3 · MAC & WINDOWS — the demo on this page is only its middle section

THALM

One piece of music, playing in one room, all the way through.

Map where the listener goes — out on the street, in at the door, up the stairwell, into a flat two floors above — and hear the music change as they move.
