Trimming audio is the most common sound editing requirement—whether you're isolating a voice clip, making custom ringtones, or trimming silence from the start of a song.

A precise audio cutter allows you to isolate a specific segment of a sound file down to the millisecond. By choosing your exact start and end times, you can crop out unwanted introductions, commercials, transitions, or silence to create a clean, focused clip.

If you need to make a custom ringtone for your mobile device, the trim audio tool is perfect. Select a 30-second window of your favorite song, preview the boundaries to ensure a clean start, boost the volume if the file is quiet using Output Gain, and download the finished MP3.

To ensure maximum speed and safety, our cutter decodes and crops files entirely inside your browser sandbox. The trimmed buffer is converted directly to a downloadable MP3, saving you from bandwidth costs and keeping your personal recordings completely private.
