WAVECOIL – Volume Booster & Equalizer

Control tab volume with a manual 3-band EQ, presets, balance, mono and limiter.

WAVECOIL turns the audio of your current browser tab into a compact, retro-inspired audio console. Boost or reduce the tab volume from 0% to 600%, shape the sound with presets or a manual 3-band equalizer, adjust the stereo balance, switch to mono, and enable the limiter to tame high peaks. FEATURES - Precise volume control in 10% steps - Standard, Voice, and Bass sound profiles - Manual low, mid, and high EQ from -12 dB to +12 dB - Stereo balance, mono output, and optional limiter - Ten live visualizers, including oscilloscope, spectrum, waterfall, phosphor, dot matrix, aurora, orbit, and tunnel views - Signal and peak indicators driven by the processed output - Audio settings remain active when the popup is closed - Automatic language detection plus manual language selection - No account, advertising, analytics, tracking, or remote code Open a regular tab that is playing audio, click WAVECOIL, and adjust the sound. Processing starts only after your explicit action and takes place locally in Chrome. Audio is not recorded, uploaded, sold, or shared. Chrome-internal pages such as chrome:// pages cannot be captured. Strong amplification can make existing clipping or distortion more noticeable, so increase the volume carefully.
