Drop in wind, mechanical drones, chainsaw revs, or any scare track. This finds the mathematically cleanest loop point — down to the exact zero-crossing sample — and crossfades it so the seam disappears. Runs all night on an SD card player with no audible click breaking the scene.
Upload your track, use Auto mode to find the best section, and the tool snaps the loop points to zero-crossings and applies a crossfade so the loop restarts with no pop or click.
It snaps the loop start and end to the exact sample where the waveform crosses zero amplitude. Cutting anywhere else causes an audible click every time the loop restarts — especially noticeable in quiet passageways and escape rooms where guests are listening closely.
Yes. It works on any audio — ambient wind, mechanical hums, chainsaw revs, animatronic motor loops, or music. For non-rhythmic sound design, Manual mode with zero-crossing snapping usually gives the cleanest result.
It exports a standard WAV file, which plays on virtually any SD card audio player, prop controller, or PA system used in haunted attractions.
