Hey Product Hunt! I am a solo developer and i have built a system wide EQ app called QCurve Equalizer.
If you are suffering from AI fatigue and are exhausted by apps that just wrap a cloud API, I built this for you.
QCurve has zero AI, no cloud processing, and no internet requirements. It is a pure, mathematics-and-physics-based native audio engine built from scratch to do one thing perfectly: make your music sound incredible.
Why I built this:
I love music and I am developer myself. When I looked for an Android EQ to match my self built DIY Bluetooth speaker, I was struggling to find what I needed. Most apps were battery hogs, introduced massive latency, or just sounded muddy. So, I spent the last few months building QCurve and wiring it directly into Android's low-level APIs.
What makes QCurve different:
AutoEQ Integration: We mathematically correct your specific headphone model to a target curve (like Harman or diffuse field) using thousands of built-in acoustic profiles.
Pro-Audio DSP Engine: Real-time Room Correction for independent L/R channel calibration, Harmonic Bass algorithms for small speakers, and dynamic multiband compression.
Hardware-Level Efficiency: Zero-latency processing designed for minimal background battery drain.
Smart Routing: Assign specific EQ profiles to different Bluetooth or wired devices, and the app will auto-switch the moment they connect.
Dynamic Theming: The entire UI dynamically recolors itself to one of 19 handcrafted palettes.
I would love to get real feedbacks from my fellow users or audiophiles. Thanks for your time.
