Audio Studio is a browser-native audio bench — trim or auto-cut silence, fade in/out, merge tracks, change speed, convert between MP3/WAV/OGG, normalize loudness, extract metadata and preview waveforms. FFmpeg.wasm handles encoding locally; nothing hits a server unless you share a file link.
Upload MP3, WAV, FLAC or M4A — or record from your microphone where supported.
Trim, convert, fade or inspect tags from the sidebar without losing your buffer.
Download the processed file or hand off to Video Studio for muxing.
