Professional 10-Band Equalizer
With 10 frequency bands from 31 Hz to 16 kHz, bring out vocals, sharpen drums, soften harsh highs, or create the perfect curve for your headphones.

Dynamic Gain Control Knobs
Inspired by real audio equipment, rotary knobs provide independent gain controls:
• Bass Gain — adds punchy impact and depth to sub-bass; ideal for hip-hop, EDM, and rock.
• Mid-Frequency Gain — keeps vocals and main instruments clear without muddying them.
A proprietary algorithm amplifies the signal without digital clipping, ensuring your bass stays tight, not boomy.

Advanced Volume Amplifier
Phone not loud enough? Safely increase overall loudness without pushing your speakers or headphones into distortion. Perfect for quiet videos, low-volume podcasts, and old recordings.

Watch your music come to life with a dynamic, sound-reactive spectrum analyzer. Full-screen mode and switchable color palettes let you see every audio detail in real time.
