Audio Trimmer

Trim audio precisely with a real waveform editor. Cut MP3, WAV, M4A, AAC, OGG, or FLAC and export to the format you need — all in your browser.

Practical guide

A long recording rarely needs to be shared as-is. Cut the useful sentence, chorus, sound effect, or podcast segment with the waveform, then normalize the trimmed audio if the exported clip has to sit next to other audio.

Example preview

Visual examples show the kind of input and output this tool is designed around.

Where this fits

Pull a quote from an interview

Use the waveform to land close to the first word and final pause, then export a file that is easier to send for review.

Clean up voice notes

Trim silence, false starts, and room noise at the beginning or end so the message starts quickly.

How to use Audio Trimmer

  1. 1Add the audio fileUpload a recording and wait for the waveform to render.
  2. 2Set start and end pointsDrag handles for a quick cut or type exact timestamps when the edit needs precision.
  3. 3Preview only the selected rangeListen through the cut before exporting so breaths, clicks, or clipped words are caught early.
  4. 4Choose format and qualityPick the output format and bitrate that fit the next use, such as MP3 for sharing or WAV for editing.
  5. 5Download the trimmed clipSave the result, then repeat with a new range if the same recording has several useful sections.

Practical notes

Use split when one file has many clips

For a lecture, album, or field recording with many sections, split a long recording may be faster than trimming one segment at a time.

Audio cleanup workflow

A precise cut is usually the first step; loudness and assembly come after the unwanted audio is gone.

Questions worth checking

How close can I set the trim points?

Use the waveform handles for speed and the timestamp fields for fine control. Previewing the selected range is the best way to catch tiny timing mistakes.

Why does the export format matter?

MP3 is easy to share, WAV is better for further editing, and compressed formats trade some quality for smaller downloads.

What should I do if the trimmed clip sounds quieter than expected?

Run the export through an audio normalizer after trimming so loudness is more consistent with the rest of your project.
