Free audio tools,
right in your browser.
Audio Sweet is home to a growing collection of free, browser-based audio tools. No installs, no accounts, no uploads to a server — everything runs locally on your machine.
A full-featured browser mixer for multi-track audio. Fader, pan, 4-band EQ, compressor, phase flip, and clip detection per channel — plus a master bus with EQ, compressor, limiter, LUFS metering, and true peak.
Automatically detect and remove silence from audio files. Set your own threshold and padding, preview the result, then export a clean file — no dead air, no wasted seconds.
Normalize audio levels by peak or target loudness, or use Smart Match to automatically comply with streaming service requirements for YouTube, Spotify, Apple Music, Tidal, and more. Batch process multiple files at once.
Upmix stereo audio to 5.1 surround sound, or fold down 5.1 to stereo or mono. Control individual channel levels, crossover frequency, surround delay, and reverb — then export a broadcast-ready WAV.
Automatically duck music or beds under dialogue and voiceover. Set a trigger track and threshold, tune attack and release, and export a mix with the ducking baked in.
Scan podcasts, VO, and interviews for "um," "uh," and other filler words. Review each flagged word on the waveform, adjust or dismiss candidates, then export a clean cut — no manual scrubbing required.
Built for audio people
Every tool on Audio Sweet is designed to be fast, focused, and free. No subscriptions, no watermarks, no file size limits. Your audio never leaves your computer — processing happens entirely in your browser using the Web Audio API.
