About this app

Experience your local music library with unmatched acoustic clarity. QCurve is a precision-engineered, high-fidelity local music player built around an advanced C++ native audio processing engine, designed specifically for audiophiles and music enthusiasts who demand absolute control over their sound.

Whether you are driving custom speaker setups, high-impedance headphones, or mobile DACs, QCurve delivers pristine audio shaping without coloring your source tracks unless you want it to.

Key Features
Precision 10-Band Equalizer: Switch effortlessly between Graphic and Parametric EQ modes. Fine-tune your frequency response with adjustable Q-factors, custom filter curves, and transparent digital summing.

Expert Dynamic Multiband EQ: Take surgical control of your tracks. Apply compression or expansion independently across specific frequency bands with customizable thresholds, ratios, attack times, release times, and soft-knee transitions.

Acoustic Sound Enhancers:

Acoustic Enhancers (Bass Boost, Mid Boost, & Brilliance): Designed for quick tonal shaping without manually adjusting every equalizer band. Bass Boost applies a tailored low-shelf filter to target sub-bass and kick drums. Mid Boost and Brilliance add warmth and high-end air across optimized frequency curves.

Headphone Crossfeed: Blends a small amount of the left and right audio channels with frequency filtering to simulate the acoustic cross-talk of physical stereo speakers. This reduces listening fatigue during extended headphone sessions.

Vocal Remover: Utilizes center-channel extraction to scoop out or suppress central vocals and lead instruments from stereo tracks, acting as a live instrumental or karaoke filter.

Bass Shelf & Mono Summing: Deep, thunderous low-end control tailored for custom subwoofers and portable audio builds.

Tube Saturation: Warm up your digital tracks with adjustable analog-style harmonic drive and automated gain compensation.

Stereo Spatial Imaging: Expand your soundstage or collapse tracks to mono with precision crossfeed filters that minimize listening fatigue.

Algorithmic Reverb & Stereo Echo: Add natural room acoustics, adjustable dampening, and tape-style delays equipped with built-in high-pass "mud killers."

Loudness Maximizer: Integrated brickwall limiting and upward normalization ensure your tracks stay clean, loud, and free of digital clipping.

Zero Telemetry & Offline First: QCurve is 100% offline. It scans your local storage (.flac, .mp3, .wav, .aac, etc.) without ever tracking your listening habits or uploading your personal data.
