AudioWave

AudioWave とは？

Audiowave is a free online audio toolkit that runs entirely in your browser — no installs, no uploads, 100% private. Convert between 10+ audio formats, batch process files with adjustable bitrate and sample rate, edit audio (cut, trim, split, join, merge, mix), apply effects (tempo, pitch, reverb, fade, normalize), separate vocals and instruments with Demucs AI, reduce noise, and extract audio from video. All powered by FFmpeg.wasm — your files never leave your device.
