Developed and integrated a standalone DC Offset Removal Effect for the audacity/audacity repository, focusing on early-stage audio correction within the editing workflow. The work involved refactoring DC offset analysis and processing logic from the existing NormalizeEffect into a reusable, independently validated DSP component, enabling per-track processing and improved progress reporting. Leveraging C++ for both audio processing and build system integration, the effect was registered in the built-in effects repository and incorporated into the CMake-based build pipeline. This enhancement increased processing headroom, improved downstream consistency, and reduced user confusion, demonstrating proficiency in C++ development, digital signal processing, and software engineering.
