Audio Cutter

How to cut an audio file

1. Add your files: drag them into the box above, or click "Choose files".
2. Drag the two handles on the waveform (or type the times), listen with "Play selection", then click "Cut audio".
3. Download the cut file, in the same format you uploaded. Uploaded files are deleted right away, and results after 30 minutes.

When to cut an audio file

Most of the time you only need a piece of a recording: the chorus of a song for a ringtone, one answer from a long interview, the useful minute of a voice message, or a clean start without the silence and the "is it recording?" at the beginning. The audio cutter keeps exactly the part you choose and leaves the rest out, without converting the file to another format.

• Making a short clip of a song to use as a ringtone or alarm sound.
• Removing the silence, noise or small talk at the start and end of a recording.
• Pulling one answer or quote out of a long interview, lecture or podcast.
• Trimming a WhatsApp voice message (.opus) before sending it to someone else.

Why the cut keeps the original quality

Many audio editors decode the whole file and compress it again when you save, which costs a little quality every time. Here, when the fade option is off, the selected part is copied straight from your file: the same bitrate, the same format and the same sound, just shorter. That is also why an MP3 stays an MP3, a WAV stays a WAV and a WhatsApp .opus voice note stays .opus.

Turning on the fade changes this. A fade has to change the volume of every sound sample at the start and the end, so the result is re-encoded as a high-quality MP3. Use it when the cut lands in the middle of music and an abrupt start would sound like a click.

Making a ringtone or alarm sound

• Pick the part people will recognize, usually the chorus or the hook, and keep it short: 20 to 30 seconds is plenty for a ringtone.
• Start the selection just before the first strong beat, then use Play selection to check it does not start mid-word.
• Turn on the fade so the sound does not stop abruptly when the call ends.
• Copy the MP3 to your phone and choose it in the sound or ringtone settings. Many Android phones accept an MP3 directly; iPhones use their own ringtone format and need a different route.

Tips for the best result

• Use "Play selection" before cutting: it plays exactly the part that will be kept.
• You can type times as minutes and seconds (1:23.5) or as seconds (83.5).
• Turn on the fade only when the cut lands in the middle of music: it avoids an abrupt start and end, but the result is re-encoded as an MP3.

About these formats

Supported formats: MP3, WAV, M4A, AAC, OGG, OPUS (WhatsApp voice notes) and FLAC. The cut keeps the same format, so there is no second compression.
