AI VolumeMaster — 800% Volume Booster & Bass

Boost any tab to 800% with real bass. On-device AI picks the sound. Equalizer, 12 voices, vocal remover, 8D, and record tab or mic.

Some videos are just too quiet. You have turned the tab up. You have turned Windows up. The slider is at 100% and the lecture recording is still a whisper. That is the problem AI VolumeMaster was built to fix — and then it keeps going. AI VolumeMaster pushes any Chrome tab to 800% of its normal volume, far past anything the browser will give you on its own. It adds a real bass control, a ten-band equalizer, voice effects, a vocal remover, 8D audio, reverb, and a recorder that captures exactly what you are hearing. All of it runs on your own machine, including the AI. Nothing you listen to is ever uploaded, and there is no account to make. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ VOLUME BOOSTER — UP TO 800% ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Eight times louder than the tab's own maximum. Quiet lecture recordings, video calls recorded on a laptop mic, phone-shot video, badly mixed podcasts, old uploads with no mastering — all usable again. The free tier reaches 400%. That is already four times what Chrome allows, and for most quiet videos it is enough on its own. Pro doubles it to the full 800%. Every tab has its own level. Music at 150% in one tab, a quiet meeting recording at 700% in another, and neither one touches the other. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ AI SCENE — DESCRIBE IT, AND IT SETS ITSELF ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Nobody wants to learn which equalizer curve suits a lecture recording. They want the lecture to be audible. So type what you are hearing — "quiet lecture recording", "podcast on a noisy train", "bass-heavy music" — and AI VolumeMaster sets the boost, the bass, the curve and the effects in one move. Ten ready-made scenes cover most of what people actually listen to, and you can save your own. Or press AI Listen. It analyses two seconds of the sound itself, measures how the energy is spread across the frequency range, and works out whether it is hearing speech, a bass-led mix or a full-range track — then suggests the scene that fits. It also recognises the site you are on and offers a scene before you type anything at all. HOW THE AI WORKS, PLAINLY: all of it is on-device audio analysis and text matching, running inside your own browser. There is no cloud model, no server, no API key and no account. Nothing you type and nothing you listen to is sent anywhere — which is exactly why this can exist in an extension that promises everything stays local. If it cannot tell what it is hearing, it says so instead of guessing. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ REAL BASS, NOT AN EQUALIZER BAND ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ A dedicated 100 Hz bass shelf sits right next to the volume slider. It is not buried in the equalizer, and it composes with whatever preset you have loaded instead of fighting it for the same filter. Free reaches the Warm position. Pro opens the whole shelf and adds the one-click Warm / Deep / Max buttons. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ TEN-BAND EQUALIZER ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 32 Hz to 16 kHz, with ten live sliders — free, all of them. A locked equalizer is a screenshot of an equalizer, and it teaches nobody what the product does. Thirteen presets are built in, covering the ordinary cases: a flat starting point, curves shaped for music, and curves shaped for speech. Five of them are free. The sliders stay live under all of them, so a preset is a starting point rather than a mode you are stuck in. Pro unlocks the remaining eight — the specialist curves you reach for once you know what you want out of the sound — and lets you save, name, export and import your own. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ VOICE CHANGER — ON THE TAB AND ON YOUR MIC ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Twelve output voices, applied to whatever the tab is playing. They range from straightforward pitch shifts to heavily processed character voices. Your microphone gets its own, separate voice. That is the point: the tab can play clean music while you sound like a robot, which is the ordinary case rather than an edge one. There are also ten characters, each of which sets the voice, the bass and the equalizer together in one click. Free includes three of the output voices, two microphone voices, and four of the characters. Pro unlocks all twelve voices and all ten characters on both. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ VOCAL REMOVER, 8D AUDIO AND REVERB ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VOCAL REMOVER — drops the lead vocal out of a stereo track and leaves the backing. Good enough for karaoke on anything with a conventional stereo mix. 8D AUDIO — the slow rotating headphone effect. Headphones only; it does nothing useful on speakers, and the extension says so rather than letting you wonder. REVERB — three room sizes, on the tab and on the microphone. The smallest is free. Real convolution, not a delay pretending to be a room. The vocal remover and 8D are Pro. They are shown, not hidden, so you can see what you would be buying. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ CLEAN UP A RECORDING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Three one-click stages for anything you are about to record: REMOVE NOISE — pulls down the hiss, the fan and the room. VOICE ONLY — keeps the speech band and drops the rest. BASS BOOST — a studio stage rather than a slider, for when it has to hit. You hear them live, and they are baked into whatever you record. Free includes one enhanced recording a day, which is enough to answer "does this actually clean up MY audio?" with your own sound rather than a screenshot. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ RECORD WHAT YOU ACTU ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Record the tab, your microphone, or both. The recording is tapped from the END of the chain, so the boost, the bass, the equalizer and the voice are already in the file. What you heard is what you get. Pick a voice, press record, and you have a voice changer that produces a file you can send to somebody. Files are saved wherever you choose, through Chrome's own Save As dialog. We never receive a copy — we could not, because nothing leaves your machine. Free records five minutes a day. Pro is unlimited, up to a one-hour safety stop so a forgotten recording cannot quietly eat your disk. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ VOLUME MIXER ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every tab AI VolumeMaster is boosting, on one screen, each with its own slider. Pull the music down when a call comes in without leaving the call. Pro. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ IT WILL NOT WRECK YOUR SPEAKERS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • A limiter and a soft clipper, so boosting cannot make it clip and crackle. • A subsonic filter that removes inaudible sub-30 Hz energy, which is the part that damages drivers without ever being heard. • Every gain change is ramped, never stepped, so nothing ever bangs. • A live peak meter, and a warning when you push into the range where it starts to matter. None of that can know how loud your own hardware is set. Eight times gain is genuinely loud. Start low, raise slowly, and take your headphones off before you push the slider. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ PRIVACY — THE SHORT VERSION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ No account. No sign-up. No analytics. No telemetry. No cookies. No ads. There are no content scripts, and no permission for any site you visit — the extension is technically incapable of reading a page. Your audio, your microphone and your recordings are processed in memory on your own device and never transmitted. The only network request this extension can make is to check a Pro licence key, and only if you have e audio at the platform level. No browser extension can reach it — not this one, and not any of the others that do not mention it. AI VolumeMaster tells you before you try, instead of looking broken. • Chrome forbids extensions on chrome:// pages and on the Web Store itself. • Boosting starts when you click the extension on a tab. It is not always-on. • 8D audio needs headphones to do anything. • The vocal remover works on conventional stereo mixes. A mono track or a track with the vocal panned oddly will not separate cleanly. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ FREE AND PRO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREE, FOREVER, NO ACCOUNT: • Volume to 400% — already four times the browser's own ceiling • The full ten-band equalizer, sliders live • Five of the thirteen presets • Bass shelf as far as Warm • Three output voices and two microphone voices • Four characters • The smallest reverb room • Noise removal, voice isolation and studio bass • Five minutes of recording a day, and one enhanced recording a day • Three preset shares PRO ADDS: • The full 800% • All thirteen presets, plus saving, naming, exporting and importing your own • The whole bass shelf, plus Warm / Deep / Max • All twelve voices and all ten characters, on the tab AND the microphone • Vocal remover and 8D audio • The two larger reverb rooms • Unlimited recording, to the one-hour safety stop • Unlimited enhanced recordings • The volume mixer • Four themes and your own accent colour • Per-site memory — every site remembers its own settings • Unlimited preset sharing SEVEN DAYS OF PRO, FREE.
