Gapless A/B Compare keeps comparison files at the same playback moment, so switching between versions is instant.

Switch between tracks at the same moment

Gapless A/B Compare keeps the audio files you add aligned, so you can switch between them instantly at the same point in playback. It applies to audio files only.

Start a comparison

On Web, choose Compare in the player and add your files to comparison slots. On iPhone, open the expanded player and choose Compare, or drag another audio file onto the mini player.

Switch the active file

Once the comparison files are ready, choose a comparison tab on Web. On iPhone, tap File A or File B. The active file changes without pausing or restarting playback.

Know the limits by surface

• Web — Free compares two audio files; Pro compares up to four.

• iPhone — Compare uses exactly two audio files, File A and File B.

• Shared folders — iPhone can compare two audio files from a shared folder. Public shared links on Web do not offer Compare.

Use it for a fair listen

Play a section you want to judge, then switch files at that exact moment. Gapless Compare saves you from manually finding the same timestamp in each version.
