Boost quiet sites up to 400% through a true-peak limiter with 4× oversampled detection. Untouched at 100%. Per-site, all on-device. Ultimate Volume Control makes quiet music and video louder, up to 400%, through a true-peak limiter of the kind used in mastering. The audio engine • Stereo-linked true-peak limiter with 4× oversampled detection and 5 ms look-ahead, to keep the boost from clipping. It catches the peaks that form between samples, not only the samples themselves. • Adjustable output ceiling, 0 to −6 dBTP, for what the boost adds: a source already above it is never turned below 100%. • No compressor. A track with room for the boost gets exact gain, its dynamics intact. • Loud music gets less boost. If a track keeps hitting the ceiling, the boost eases down over a few seconds, leaving the limiter about 1 dB of work. It stays lowered on that page, across tracks, until you click "Restore boost", raise the slider, reload or open another page. • Bit-exact at 100%: the limiter passes every sample through unchanged. • Meters: momentary and short-term loudness to ITU-R BS.1770-4, true peak in and out, and limiter gain reduction. • Light on the processor: it runs on Chrome's audio thread where the page allows it, and its own engine rests when nothing plays. Per site Choose "Allow on this site only" or "Allow on all sites", and each site keeps its own volume. So can a single page or a pattern of addresses. The icon turns green while boosting and red when the boost has stopped or can't reach the sound, and the tooltip gives the real boost. "Hear original" compares with the untouched sound in one click. Very loud boosts can be hard on ears and speakers, so raise the volume gradually. Private No account, no servers, no analytics. Sound never leaves your device. About Chrome's warnings Chrome says the extension can "read and change all your data on all websites" because it can capture a tab's sound. It captures a tab only when you boost it from the extension and the site's sound can't be reached from inside the page. Chrome then shows the tab as shared, but the sound goes only to your speakers. With "Allow on all sites", a small script loads on every page so a boost can start in time, and it leaves the sound untouched until you choose a volume there. Icon designed by gravisio from Flaticon.
