MP3 Cutter
Drag the green START and amber END tab handles on the waveform, or type exact timestamps. A live playhead shows your position as audio plays.
MP3 Splitter
The live segment preview bar updates as you adjust settings — see exactly how the file divides before processing. Equal parts or precise timestamp markers.
MP3 Merger with Per-clip Trimming
Expand any file in the merger queue with Edit Clip to set its own start and end points. Each clip's trim region is shown inline, and the final merge only includes your selected portions.
