Experience your offline music library with unmatched acoustic clarity. QCurve is a high-fidelity offline music player and precision audio equalizer built around an advanced native C++ DSP engine. Designed for audiophiles and audio engineers, it is the ultimate MP3 and FLAC player for those who demand absolute control over their sound.
I’m the solo developer behind QCurve Music Player.
Outside of software, I design and build custom physical loudspeaker arrays and analog audio amplifiers. But when it came to listening to my local FLAC and MP3 libraries on Android, I couldn't find a mobile player that matched that hardware-level precision. The market is saturated with players that are either bloated with memory-hogging SDKs, riddled with screen-hijacking ads, or reliant on standard OS audio APIs that lack true signal control.
I wanted a premium, offline-first utility for true audiophiles—so I built one from scratch.
QCurve is built on a custom 32-bit float native C++ DSP engine using Oboe AAudio. It bypasses standard audio bottlenecks to give you zero-latency, bit-perfect control over your local library while maintaining an incredibly lean memory footprint.
Core Features:
Hybrid 10-Band EQ: Seamlessly switch between a standard Graphic EQ (GEQ) and a full Parametric EQ (PEQ) with pinpoint Frequency and Q-factor sweeping.
Audiophile FX: Headphone Crossfeed, Tube Saturation (analog warmth), Tape Rolloff, dynamic Silence Trimming, and a custom Reverb matrix.
Phantom Sub: A psychoacoustic bass enhancer that synthesizes 2nd and 3rd harmonics, allowing deep sub-bass to be heard on compact Bluetooth speakers and earbuds without distorting the driver.
Synchronized Lyrics (New in v1.3): A zero-bloat, 3-tier offline-first lyrics engine. It reads your local .lrc files first, falls back to the open-source LRCLIB API if missing, and caches directly to disk.
Zero UI Clutter: A purely gesture-driven edge-to-edge UI, featuring a highly-optimized 60fps real-time spectrum visualizer that auto-sleeps to save battery.
What feedback would help most?
Because Android hardware and OEM audio routing are notoriously fragmented, I am actively looking for feedback on:
1. DSP Stability: How do the Parametric EQ and Phantom Sub perform on your specific device architecture?
2. The UI/UX Flow: Does the new synchronized lyrics transition feel natural? Is the tri-state folder manager handling your massive SD-card libraries smoothly?
