No bloat. No ads. No accounts. Just clean, powerful audio control.
━━━━━━━━━━━━━━━━━━ PARAMETRIC EQUALIZER ━━━━━━━━━━━━━━━━━━ • 8 fully adjustable bands • Filter types: Bell, Low/High Shelf, Low/High Pass, Notch, Band Pass • Drag points directly on the response curve • Three views: Parametric curve, Graphic sliders, and a precise Table editor • Per-band frequency, gain, and Q control

This app is Soo addicting! I love the name Tone box! I am an audiophile, and you did Soo good!! In the Limiter and multi band compressor can you change the Release minimum from 5 ms to 0.1 ms? That way the music will punch more Aggressively like apples dsp when headphones are on and gain turned up?

Listen I've been using Powerade for a year now. But newer versions of android and OneUi is messing with it badly and causing issues. Your PEQ app is absolutely goated and for it to be free is just the icing on the cake but even if there's a cost I'd happily pay for it. Your app is a hidden gem my friend. And I hope more sees it in time man. This will be my new permanent EQ app going forward. Thank you truly.
