How It Works

1Upload an audio file by clicking the drop zone or dragging it in, or switch to the "Record Audio" tab to record from your microphone.
2Use the timeline to preview the audio. Drag the green handle (or the Start slider) to set the cut start, and the red handle (or the End slider) to set the cut end. You can also play to the desired position and click "Set current position as start/end".
3Press Play to hear a preview of the full audio. The highlighted region on the timeline shows exactly what will be exported.
4Click "Download cut WAV" to save the selected segment as a lossless 32-bit float PCM WAV file. All processing happens in your browser — nothing is uploaded.
