HOW IT WORKS
A polished loop in three steps
No audio engineering degree required. See the waveform, listen to the seam, and fine-tune it.
Choose the range
Set precise in and out points with handles, zoom and time fields.
Preview and export
Loop the crossfaded result, then save it in your preferred format.
SMOOTH BY DESIGN
A smoother seam with crossfade
A hard cut can click or jump when the end and beginning have different levels or shapes. LoopTone overlaps the edges with an equal-power fade, making the transition feel continuous.
GuideFine visual control
Waveform, minimap and millisecond time fields for accurate loop points.
Listen before saving
Switch between the original range and the finished seamless preview.
Export for any workflow
Save one cycle or a repeated version as WAV, MP3 or Opus.
