Graphic Equalizer

Drag the frequency bands up and down and hear your audio change instantly — that's the whole idea. Graphic Equalizer puts a 31-band EQ in your browser, modeled after the hardware units you'd find in a recording studio or live sound rack. Boost the low end for more warmth, cut harsh mids, roll off high-frequency hiss — every adjustment shapes the sound in real time as you move the sliders.

It's a practical tool for anyone who wants more control over how audio sounds on their current speakers or headphones. If you've ever wished a track had more bass, or that a podcast voice sounded less tinny, this is exactly the kind of hands-on fix that delivers. It fits naturally alongside other music apps built for experimenting with sound rather than just listening passively. For a different angle on the same audio, Spectro shows you a live spectrogram of whatever you're hearing — useful for seeing which frequencies you're actually cutting or boosting.

Works best with headphones, where frequency differences are easier to hear clearly.
