Worked on the videolan/vlc repository to enhance the stability and fidelity of the Chorus/Flanger audio filter using C programming and audio processing expertise. Addressed memory allocation issues by correcting buffer sizing and ensuring zero-initialization after reallocations, which prevented heap corruption and uninitialized memory access. Improved audio playback accuracy by refining duration timing calculations and synchronizing output buffer lengths with input samples, using system programming techniques. These changes resulted in more reliable real-time audio processing, especially during dynamic delay adjustments, and preserved user-facing audio quality. The work demonstrated careful attention to runtime stability and precise handling of low-level audio data.
