This paper presents the GLYXEN Smart Audio system, an innovative hardware-software ecosystem designed for high-fidelity audio reproduction in dynamic environments. The system addresses two primary challenges in modern acoustics: real-time room acoustic correction and automatic environment adaptation. Unlike traditional systems that require dedicated measurement microphones, GLYXEN utilizes the currently playing music as an excitation signal for Room Impulse Response (RIR) estimation. Furthermore, the system integrates WiFi-based room fingerprinting to automatically detect the device's location and switch between pre-calibrated Digital Signal Processing (DSP) profiles. Implemented on a custom Yocto-based Linux distribution (Glyxen OS), the system demonstrates a seamless, microphone-free approach to adaptive audio correction on embedded hardware.
