What is an audio trimmer?

An audio trimmer keeps one continuous section of a longer file. It is the fastest option when the only goal is to remove material before the chosen start point and after the chosen end point.

Unlike a full editor, the trimmer presents one focused range instead of a multi-clip project. Exact time fields and loop preview make it easier to confirm the cut before export.

Set exact boundaries

Drag waveform handles or enter start and end times to define the section that should remain.

Loop-preview the selection

Listen repeatedly to the chosen section so the start and ending feel correct before rendering.

Add short fades

Smooth an abrupt beginning or ending without opening a larger audio editor.

Export to the format you need

Save the trimmed section as MP3, WAV, M4A, FLAC, OGG, or AAC.
