How to cut an excerpt using seconds

  1. Find the first sound

    Listen to your source and note where the phrase, cue or effect begins.

  2. Enter start and length

    Set Start to the offset in seconds and Length to the duration you want to keep. For seconds 12 through 20, enter 12 and 8.

  3. Save and check the cut

    Choose Trim audio and download the MP3. Listen for clipped syllables at either edge.

Keep the part that earns its place

Use time-based trimming when you already know which phrase or sound the next edit needs.

Pull a testimonial quote

Cut the approved sentence from a longer customer recording and leave enough room for the final consonant.

Choose one voiceover take

Extract the preferred read from a session with repeated attempts.

Isolate a product sound

Keep the click of a clasp or the pour of a drink as a short reference cue.

Send a music excerpt for review

Share only the section that will play under a draft reel so the reviewer hears the intended timing.

Audio trimmer FAQ

How do I keep a complete sentence from a longer take?

Start a little before the first consonant and end after the last syllable. Enter the length of that section in seconds, then play the exported cut to check both edges.

Is Length an end timestamp?

Length is the number of seconds to keep after Start. To keep seconds 30 through 42, enter Start 30 and Length 12.

Can I enter fractions of a second?

Yes. The tool accepts decimal seconds, with a requested length from 0.01 to 300 seconds.

What happens if my selection runs past the end?

The export stops when the recording ends. Choose a start point before the final moment of the source.

How do I export the part between 12 and 18 seconds?

Set Start to 12 and Length to 6. Length measures how much audio to keep from the start point.

Which format will my excerpt download in?

The trimmer exports trimmed.mp3 at 192 kbps. Keep the source if you also need the original format.

Can I take a short audio cue from a video?

Yes. Select a video that has sound, then set Start and Length. The excerpt downloads as audio only.
