Spatial audio as a visible control signal

Place the sound.

Choose a trained reverb size and dry/wet category, switch the outdoor space between day and night, or route through experimental Dual Delay SFX. The holographic volume is a legible proxy for the caption the model actually learned.

The approach

Spatially aware generation.

A generated video can place a performer in a cathedral, an empty club or an open field while the voice still sounds like a close, dry studio recording. The picture describes a space, but the sound ignores it. That mismatch is one reason otherwise convincing generated footage can still feel synthetic.

AKUSPACE closes that gap by re-generating the take with the acoustic character of the scene. The performance returns inside the requested room or place, with its timing preserved for synced video. It does not change the pixels; it makes the picture and sound feel as though they belong to the same environment.

Beyond rooms and outdoor places, the same control surface reaches original Eurorack modular treatments. This brings prompt-controlled sound effects into the same workflow: a less explored direction for generative audio and video.

Where the material comes from

All training material is owned and was recorded or produced for the project over several years. It includes multiple speaking voices, beats and electronic music, percussion, and acoustic instruments.

The treatments come from digital reverbs, custom presets, original Eurorack modular patches and original field recordings used for the outdoor beds. Together they cover spaces, places and sound effects. Nothing was scraped, and no third-party licensed audio was used for training.

How it is built

Every training item contains the same performance twice: once dry and once through a real treatment chain. This teaches the model a transformation instead of an association between particular sounds and particular environments.

Rooms and sound effects are represented at three trained amounts — gentle, moderate and heavy. Outdoor places use gentle and heavy. The level word occupies the same position in every caption, giving the model a consistent semantic control rather than an arbitrary number. The ComfyUI nodes emit those exact strings, so users select the space and amount instead of guessing the wording.
