• Precise selection with millisecond time inputs
• Cut, crop, split and silence

• Compact editor and full-screen editing workspace
• Projects saved locally in the browser
• WAV export at 44.1 or 48 kHz

All decoding, editing, recording, project storage and exporting happen locally on your device. Audio Edit has no accounts, analytics, advertising, trackers, remote code or network requests.
