Select the part of an audio file you want to keep

Open an audio file your browser can decode. Drag the waveform selection or enter start and end times to extract a song clip, remove unwanted lead-in or trailing audio, prepare a podcast excerpt or create a ringtone.

• Fade in and out: change the volume gradually at the beginning and end.
• Volume: adjust the selected clip's overall level.
• Speed and pitch: set speed between 0.5× and 2× and pitch between −12 and +12 semitones independently.
• Result preview: generate and listen to the cut with its effects before downloading.
• Formats and presets: choose an export format and save frequently used effect settings.

How to trim and preview

1. Import a file and wait for its waveform.
2. Set the clip boundaries and any effects.
3. Preview the result to check the cut, volume and transitions.
4. After changing settings, preview again, then choose a format and download.

The preview uses a browser-friendly audio format. Downloading encodes the selected output format with the same boundaries and effects; compressed formats can sound different from the preview.

Frequently asked questions

Can I make an iPhone ringtone?

Choose M4R output or start with the ringtone effect preset. After downloading, transfer the file to your phone using a method supported by the device.

Is every cut lossless?

No. Export re-encodes the audio, and lossy formats such as MP3 or AAC may change its quality. WAV and FLAC avoid adding lossy compression, but cannot restore information missing from the source.

Are audio files sent to a conversion server?

Processing runs in the browser. The audio engine needs to load on first use, and practical file sizes depend on browser and device memory.

For Morse recordings, isolate a clear segment here and then use the Morse audio decoder.
