Fix loud movies, quiet dialogue and harsh audio on any site. Compressor, volume boost, de-esser, sub bass, exciter and mono.

Make any video or audio in your browser sound better: even out loud explosions and quiet dialogue, cut harsh "s" sounds, add deep sub bass or extra sparkle, all with one click. Audio Karate is a real-time audio processor for the web. Open it on a page with a video or audio player, pick a mode, and the sound is processed instantly. No reload, no account, no setup. ONE-CLICK MODES • Movie: tames sudden loud scenes and lifts quiet dialogue, so you stop reaching for the volume • Speech: strong, fast leveling for podcasts, lectures, interviews and calls, so every word is clear • Music: gentle compression that keeps the punch and dynamics of the track SOUND TOOLS • Volume Boost: up to +20 dB for quiet videos and weak laptop speakers • Gain reduction meter: watch the compressor work in real time • De-Esser: turns down harsh sibilance ("s", "sh", "t") only when it gets loud, without dulling the rest • 80 Hz Cut: removes low-end rumble and boominess, great for small speakers and voice • Mono: plays both channels on both sides, ideal for one earbud, a single speaker, or old hard-panned recordings • Bypass: instantly compare processed and original sound ADVANCED CONTROLS • Compressor Threshold, Ratio, Attack and Release for full manual control • Sub Bass: boost the low end (up to +12 dB) with an adjustable frequency, made for headphones and full-range speakers • Exciter: adds new high harmonics for presence and air, which is more natural than a treble boost. Tune sets where it starts. • A built-in safety limiter stops the sub bass and exciter from clipping SMOOTH AND SAFE • All changes glide in smoothly, without clicks or pops • Your settings are remembered, so every tab picks up where you left off • Works on most sites with HTML5 video and audio, including players that load after the page PRIVACY Audio Karate only runs on a tab when you click its icon. It doesn't collect, store or send any data. All processing happens locally in your browser.
