LoopHog od tomhog

Pick a start and end point on any YouTube video and LoopHog loops that section seamlessly. Instead of seeking the player back and forth, it captures the region once and loops the audio buffer, so there is no stutter and no click at the wrap, and effect tails carry across the seam.

Shape the sound with presets like slowed + reverb, nightcore, daycore, bass boosted and lo-fi, or dial in your own speed, reverb, filter, bass and ambient layers (vinyl, rain, tape). You can hold the pitch steady while changing speed. Snap the loop to whole bars or beats at the detected tempo so it repeats musically.

Share a loop by copying a link. The loop points and settings are encoded in the URL itself, so anyone with LoopHog installed hears exactly what you heard. Save loops per video and get them back next time.

Keyboard shortcuts: Ctrl+Alt+A and Ctrl+Alt+B set the region, Ctrl+Alt+L starts and stops the loop, Ctrl+Alt+H hides the panel.
