AhmadHassan-BTed/AhSilence

This system is an Android application featuring a native Active Noise Cancellation (ANC) engine built with the Oboe library and C++. It processes audio in real-time using an adaptive filter to generate anti-noise, allowing for dynamic adjustment of gain and phase parameters. The architecture utilizes a multi-module structure with dependency injection to manage the foreground service and DSP engine, ensuring low-latency performance and centralized configuration.

The application now includes a native Android library (ancengine) that implements Active Noise Cancellation using the Oboe audio streaming library. This engine processes audio in real-time via a FullDuplexStream, utilizing a narrowband Filtered-X Normalized LMS (FxNLMS) adaptive filter to generate anti-noise based on a synthesized reference oscillator. Users benefit from a native, low-latency implementation that allows for dynamic adjustment of gain and phase parameters to target specific noise frequencies.

The foreground service handling the anti-noise emission has been restructured to remove hardcoded configuration values and tight coupling. Intent actions, notification identifiers, and default calibration parameters are now sourced from a centralized \AudioConstants\ object, while the DSP engine is resolved via a new \AudioEngineLocator\ dependency injection mechanism. This change also updates the service to use string resources for notification text and channel names, and adds the necessary Android manifest permissions for audio recording and foreground media playback.

app/src · high confidence

The project has been initialized with a multi-module structure, adding a new ':ancengine' module for native audio processing. This module integrates the Oboe library (v1.10.0) for low-latency audio streaming and uses CMake for native compilation. The main app module now depends on this engine and adopts a version catalog for dependency management, explicitly including AndroidX Lifecycle ViewModel Compose (v2.8.3) and Kotlinx Coroutines (v1.8.1). Build configurations have been standardized to use SDK 36, NDK 27.1, and Java/Kotlin 11, with release builds enabling minification and resource shrinking. Additionally, Gradle properties were updated to enable parallel execution, configuration caching, and build caching for improved performance.
