Nov 1, 2025

November 2025 monthly summary for audacity/audacity highlighting key features, fixes, and technical achievements. Real-time track handling when opening a project was stabilized to prevent drifting state by correctly managing track IDs, ensuring real-time effects apply reliably on load. The meter UI responsiveness was enhanced by increasing the update rate from 30Hz to 60Hz, delivering smoother visual feedback during playback and editing. Spectrogram-related improvements include: (1) column width customization for global vs. track-specific settings, (2) real-time repaints when global or track settings change, and (3) a major spectrogram rendering architecture overhaul with refactoring of painter classes, task splitting, and alignment of per-track vs global configuration. These changes improve user experience, reliability, and maintainability, and lay groundwork for future spectral tooling enhancements.

October 2025

Oct 1, 2025

Month: October 2025 (audacity/audacity). This month focused on delivering a key feature for long-running operations and stabilizing audio playback, delivering measurable improvements in user experience and reliability. Key features delivered include configurable titles for progress dialogs to provide context during long operations. Major bugs fixed include improvements to audio playback stability: jitter compensation in play cursor positioning, ensuring the playback cursor resets on resume, increasing the audio callback queue to reduce overflow risk with small buffers, and ensuring that playback does not consume more samples than have been output to prevent glitches. Overall impact: enhanced user experience during long tasks, improved playback reliability and predictability, and better resource utilization. Technologies demonstrated: C++, real-time audio processing, UI/UX improvements, debugging and performance tuning. This work lays groundwork for more robust long-running operation handling and more reliable audio playback across platforms.
