AI sound effects that placethemselves
Describe a sound and get it. Or turn on Auto SoundFX and let Shorz read the transcript and drop the right effect where the words call for it — plus whooshes on every B-roll, transition, emoji and zoom.
How to use the ai sound effects generator in three steps
Sound design is the fastest way to make an edit feel expensive, and the slowest thing to do by hand — every whoosh is a search, a download, a drag and a nudge. Shorz does the placement: the transcript tells it where a sound belongs, and every B-roll insert, transition, emoji and zoom can carry its own effect automatically.
Turn on Auto SoundFX
One switch. Shorz reads the transcript and places effects from a bundled library of 144 sounds where they actually fit — no searching, no dragging, and no credits spent.
Transcript-driven placement
Generate the one you can't find
Need something specific — a retro modem, a slow metallic door, a crowd gasp? Describe it and Shorz generates the effect and saves it to your library for reuse.
Text to sound effect
Attach sounds to the edit itself
Give B-roll appearances, transitions, emojis and zooms their own sounds. The effect fires exactly when the visual does, because the edit and the sound design are the same pass.
