Learn more about AI sound effect generation

Describe the event, material, environment and listener perspective so your agent can create a sound that fits the scene rather than a generic effect.

Build the sound from observable details

Name what causes the sound, the surface or material involved, the space around it, the distance from the listener and the required duration. Say whether it must be isolated, layered or loopable.

How should I review a generated sound effect?

Listen in the intended scene and on the target playback device. Check timing, unwanted ambience, clipping, tonal fit, loop seams and whether the effect competes with speech or music.

Generate short variations before polishing

Ask for a small range that changes one useful quality, such as weight, distance or intensity. Choose the strongest direction before requesting a longer or more precisely timed version.

Example prompt

This prompt anchors the effect in a physical event and listening perspective.

Example prompt to give your agent

Use Scrollport's Sound effect generation capability to create [DURATION] of [EVENT] involving [MATERIAL OR SURFACE] in [ENVIRONMENT], heard from [LISTENER PERSPECTIVE]. It should feel [WEIGHT, INTENSITY OR TONE], be [ISOLATED OR LAYERED], and [LOOP OR END] cleanly. Avoid [UNWANTED SOUNDS] and show me the price before the paid run.
