AI VolumeMaster — 800% Volume Booster & Bass

Boost quiet tabs to 800%, add bass, tune a 10-band EQ, change voices and record. Runs locally. 7-day Pro trial, no card.

Some videos are just too quiet. The tab is at 100%, but the lesson is still a whisper, dialogue disappears, or your music sounds thin. AI VolumeMaster is a Chrome volume booster with a practical audio control desk: a ten-band equalizer, dedicated bass, clearer listening modes, DJ tempo and tune, voice effects and local recording. Improve what you already play without uploading it to a processing service. INSTALL FREE. TRY EVERY PRO FEATURE FOR SEVEN DAYS. NO CARD AND NOTHING TO CANCEL. Eligible new installations start the trial automatically. Afterwards, Free remains available unless you separately purchase Pro. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ QUIET VIDEOS, CLEARER SPEECH, LESS SLIDER CHASING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Raise quiet lessons, interviews and home videos. Free reaches 400% signal gain; trial and Pro reach 800%. Each processed tab keeps its own level, so boosting a lesson does not raise every other source. Free includes Dialogue and Night modes for quiet speech and loud moments. Dialogue helps words stand out; Night also reduces low-end weight for a more restrained balance. Mono combines the stereo channels; left/right balance shifts output toward your preferred side. Compare original and processed sound before choosing settings. Comparison is disabled during recording to avoid interrupting a take. Percentages mean signal gain, not four or eight times the perceived loudness. Results depend on the source and hardware; these are listening tools, not medical hearing correction. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ DJ TEMPO AND TUNE: YOUR OWN PACE, YOUR OWN KEY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ A dedicated DJ tab keeps creative controls separate. Adjust compatible web media from 0.50x to 2.00x speed in 0.01 steps, with quick choices for 0.75x, 1.00x, 1.25x and 1.50x. Slow a tutorial, practise a passage or explore a different pace. Tune shifts captured tab audio up or down by six semitones. Drag either dial, scroll over it or use keyboard controls; numeric readouts make changes repeatable. Key lock asks the browser to preserve pitch while changing speed. Reset returns tempo and tune to normal. Works with supported HTML5 players, including compatible YouTube playback. Sites may override speed changes. Tune is transposition, not automatic pitch correction, note detection, beat matching or an Auto-Tune engine. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ RECORD THE RESULT: FULL TAKES OR A SHORT A-TO-B CLIP ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Save supported tab audio after processing, with gain, tone, voice and enabled effects included. Make a separate microphone take for your own spoken notes or creative experiments. Recordings stay local; the extension does not upload them. Want one section? Choose Start clip (A) in the DJ tab, let it play, then stop at B and save. This is live start-and-stop capture, not timestamp extraction, automatic A-B looping or sample-accurate trimming. Export is audio-only WebM/Opus, not MP3, WAV or video; check your editor's support. Format conversion is separate. Tab and mic takes are separate files, not a multitrack export. Free provides five minutes per local calendar day across your takes. Trial and Pro have no daily time quota, with a one-hour maximum per recording. Save through Chrome's download handling and only capture material you are authorised to record. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ AI SCENES: DESCRIBE THE LISTENING PROBLEM ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Type "quiet lecture recording", "podcast on a noisy train" or "bass-heavy music" and get a matching starting point. Ten built-in scenes bring related controls together, with availability following your plan. Pro also supports named custom scenes. AI Listen analyses about two seconds of captured sound and suggests a speech-led, bass-led or fuller-range configuration. You decide whether to apply it. HOW IT WORKS: local text matching and frequency-energy analysis, not a generative model. No API key, remote prompt processing or audio upload. Suggestions are starting points, not guaranteed improvements. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ REAL BASS AND A TEN-BAND EQUALIZER ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ A dedicated 100 Hz bass shelf adds warmth alongside your chosen tone curve. Free reaches Warm; trial and Pro unlock the full shelf and deeper quick settings. All ten manual frequency sliders are available on Free, from 32 Hz to 16 kHz, with up to 12 dB of boost or cut per band. Reduce boom, soften sharp treble or bring spoken detail forward. Thirteen built-in presets provide starting points. Free includes Flat, Rock, Pop, Jazz and Classical. Trial and Pro add Electronic, Hip-Hop, Acoustic, Vocal, Bass Boost, Treble Boost, Loudness and Podcast. Presets remain editable. Make small changes; Flat provides a neutral reference. More bass is not always better, and software cannot exceed your speakers' physical range. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ SAVE, EXPORT AND IMPORT YOUR FAVOURITE SETTINGS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Open preset management with Save. Trial and Pro let you name custom presets instead of rebuilding settings from memory. Download stored presets as a .json backup and import a compatible file to restore or move them. JSON contains settings, not audio. A backup requires stored presets first. File backup/import does not spend the copy-and-paste sharing quota. Free includes three combined text-based preset import/export actions; Pro removes that quota. Imported settings are validated, and paid features still follow your plan. Importing a file does not unlock Pro effects. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ VOICE EFFECTS, CHARACTER PRESETS AND YOUR MICROPHONE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Try pitch-shifted, robotic, telephone-style and other creative treatments. Twelve voice choices include the unprocessed None option. Ten character presets combine voice, tone and bass for a quicker starting point. Free includes Baby, Alien and Chipmunk on the tab, Baby and Chipmunk on the mic, plus original sound. Four character presets are available on Free; trial and Pro unlock the full collection. Your microphone has a separate processing path and voice selection. Enable it, grant Chrome permission, then monitor available effects and record locally. Keep tab playback clean while trying a different character on your own voice. Headphones help reduce speaker-to-mic feedback. Mic access is optional. This is not a virtual mic driver: effects are for local monitoring and recording, not voice replacement in other apps. They are not voice cloning. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ KARAOKE, 8D MOVEMENT AND ROOM REVERB ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VOCAL REDUCTION uses stereo centre cancellation for karaoke-style backing on suitable mixes. Mono sources, off-centre vocals and centre-panned instruments limit the result. This is not neural stem separation or guaranteed clean isolation. 8D AUDIO adds slow left/right movement for headphones, not a certified surround format. Both features are available during the trial and with Pro. REVERB offers Room, Hall and Cathedral-style spaces. Room is available on Free; trial and Pro unlock the larger spaces. Start lightly, especially on speech, where too much room can obscure words. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ RECORDING CLEANUP: HEAR IT BEFORE SAVING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ REMOVE NOISE filters low rumble, mains hum and high-frequency hiss. It is spectral shaping, not a noise gate or universal background-noise removal. VOICE ONLY emphasises the centre and speech-frequency range; it does not perfectly separate speech from music. BASS BOOST adds a stronger studio low-end treatment. Preview stages live and record the result. Free includes one enhanced take per day within its time budget; trial and Pro remove that quota. Test a sample first: results depend on the source. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ MULTI-TAB MIXER: KEEP BACKGROUND SOUND IN ITS PLACE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Trial and Pro show actively processed tabs with separate sliders. Keep music low and the explanation clear without jumping between players. Set one captured tab to 10%, another to 30% and another to 40%. These are independent gain settings, not shares that must total 100%. Raise, lower or mute each source to suit your listening. The mixer shows tabs already being processed. It does not silently capture every page, mix all desktop apps or automatically synchronise unrelated players. It is source-level balancing, not a virtual audio cable. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ LIVE METERS AND A PRO FREQUENCY LINE VIEW ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Animated frequency bars and a live peak display make adjustments easier to follow. Green, yellow and red regions give visible feedback as signal levels move. Trial and Pro add a frequency-spectrum line view for a continuous visual curve. Compare how a tone change affects the displayed balance, not just the slider position. These display digital signals, not loudness at your ears. The line view is not a waveform editor. If audio sounds harsh, lower gain and effects; brighter meters do not mean better sound. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ A PREMIUM CONTROL DESK THAT FITS YOUR ROUTINE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Volume, DJ, EQ, Output, Mic, Mix and Pro have separate tabs. Everyday controls stay within reach, without creative tools crowding the same screen. Top controls provide Reset, Save and a feature tour. Reset restores tab and DJ defaults; the tour highlights individual controls. Trial and Pro add Dark, Light, Cyber and DJ themes and a custom accent colour. Keyboard commands increase, decrease, mute or reset the processed tab. Defaults are Alt+Shift+Up, Alt+Shift+Down, Alt+Shift+M and Alt+Shift+0; review or change bindings in Chrome's extension-shortcut settings if another command conflicts. Pro's per-site memory reuses preferences for an origin. It is off by default. Settings stay local, without cloud synchronisation or a viewing history. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ COMPATIBILITY AND SENSIBLE GAIN HANDLING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Built for desktop Chrome 116 or later and supported tab audio. Invoke the extension on the tab you want to adjust. Protected content and some players restrict capture or control; Chrome blocks scripting on chrome:// pages and the Chrome Web Store. The audio chain uses a low-frequency filter, limiter, soft clipping and smoothed gain changes to help manage peaks. The interface warns at higher gain levels. None of this guarantees distortion-free sound, prevents hardware damage or makes loud listening safe. Start low and raise gradually. Boost can also raise hiss already present in a recording. If you hear crackling or strain, back off. Tempo depends on the player, stereo effects need suitable material, and mic tools need permission and an input device. This is not a system-wide driver, mobile app or DRM bypass. Only save content you own or are authorised to record. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ PRIVACY: YOUR SOUND IS PROCESSED ON YOUR DEVICE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Tab audio, mic processing, scene analysis and recordings run locally. Those streams and takes are not sent to a cloud processing service. No extension account is required for Free or the trial. There are no built-in advertising or analytics trackers. Settings, presets, trial state and licence data use local storage. DJ scripting temporarily accesses the invoked tab's media elements; it is not permanent permission for every website. Paid licence activation, validation and seat management connect to Lemon Squeezy. The publisher's uninstall page can receive licence and instance information to release an activation. Checkout, support and sharing open external pages with their own privacy practices. Local audio processing does not mean every linked website is offline. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ FREE, TRIAL AND PRO: THE LIMITS UP FRONT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREE, WITH NO EXTENSION ACCOUNT REQUIRED: • Up to 400% gain and bass through Warm. • Ten manual EQ sliders and five tone presets. • Dialogue, Night, mono and left/right balance. • DJ tempo and tune on compatible media. • Three processed tab voices, two mic voices and four characters. • Room reverb, live bars and peak feedback. • Five minutes of recording per day across takes. • One enhanced take per day within that allowance. • Three combined text-based preset import/export actions. • JSON backup/import for stored presets, separate from text sharing.

Review billing, renewal and cancellation terms before purchasing. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ WHY USE IT, AND HOW TO START ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FOR STUDY: raise a quiet lesson, try Dialogue and slow a difficult passage. Follow the explanation instead of repeatedly reaching for the system slider. FOR MUSIC: personalise the low end, explore a tone curve and try the DJ controls. Keep the original when it sounds best. FOR EVENINGS: try Night at a modest level. FOR YOUR OWN AUDIO: preview an effect and save a short local take. FOR MULTITASKING: balance background sources with the Pro mixer. GET STARTED: choose Add to Chrome, open supported audio and invoke the extension on that tab. Begin low, try a listening mode and explore the trial tools. Reset returns you to neutral. About offers Copy share link and social, messaging and email options. No review, rating or referral is required for the trial. Judge Pro with your actual audio before buying. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ PERMISSIONS: WHAT THEY ARE USED FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ tabCapture: selected tab audio capture after your interaction. offscreen: the audio engine while the popup is closed. storage: local settings, presets, trial state and licence data. activeTab: temporary access to the tab where you invoke the extension. scripting: supported media speed and pitch-preservation controls for DJ tools. downloads: recordings and preset backups you request.
