Whether you need to extract the perfect 30-second ringtone from a song, trim silence from a podcast recording, or isolate a specific audio clip from a long file — our browser-based waveform cutter gives you sample-accurate control. The entire operation runs locally using the browser's Web Audio API, so you can work with audio files of any size with complete privacy.
How the WAV Export Works
DecodeBrowser decodes your MP3/OGG to raw PCM float samples via AudioContext.decodeAudioData().
SliceWe read only the samples between your start and end sample positions — no re-encoding.
WAV WriteA WAV file header is assembled in JavaScript, writing the raw PCM samples with correct sample-rate metadata.
