About the Audio Trimmer & Cutter
Load an MP3, WAV, M4A, OGG, FLAC or a video file, drag the range handles to the exact start and end point, then render the cut with optional fade-in, fade-out, volume change and a mix-to-mono option. Everything is decoded and rendered offline with the Web Audio API, so the file never leaves your device.
