Loop & Repeat Audio Online Free

Audio looping means repeating a sound file multiple times to create a longer version. Musicians use it for practice tracks, DJs for extended mixes, meditation creators for ambient soundscapes, and content creators for background audio.

Crossfade blends the end of one repeat into the beginning of the next, creating a smooth, seamless transition. Without crossfade, you may hear a click or abrupt cut where repeats join. Crossfade is essential for music loops and ambient sounds.

Yes. Enable A/B loop and drag the markers on the waveform to select the exact section you want to repeat. Only that section will be looped — the rest of the file is ignored.

Switch to "Target duration" mode and enter your desired duration (for example, 1 hour). The tool automatically calculates how many repeats are needed. Add crossfade for seamless transitions between repeats.

Processing happens in your browser using your device's RAM. Source files up to 2 GB are accepted. For very large outputs, the tool shows estimated size and warns if it may exceed available memory.

Reverse alternation plays every other repeat backwards: forward, backward, forward, backward, and so on. Combined with crossfade, it produces a smooth palindrome-like loop — popular in ambient and experimental music production.
