Worked on enhancing the reliability and security of BPM detection in the audacity/audacity repository, focusing on robust error handling in C++. Addressed a known vulnerability (CVE-2018-17096) by replacing assertions with runtime exceptions to manage invalid sample rates, thereby reducing the risk of crashes from malformed inputs. The approach centered on runtime error handling, improving the stability of audio processing workflows without introducing new features. This work involved careful analysis of error conditions and implementation of defensive programming techniques, resulting in a more resilient BPM detection component. The changes contributed to a safer and more reliable user experience in audio applications.
