v2.0.0 - Complete Rewrite: Stable & Efficient

The macOS download of this release was removed on October 3, 2026. The macOS FFmpeg inside was a build that we may not pass on (it was configured as "nonfree"). Please use the macOS download of v2.0.2 instead: it has an FFmpeg we built from FFmpeg's source, which may be shared. A copy you already installed keeps working. The Windows download is not affected.

🎉 Version 2.0.0 - Major Stability Release

This is a complete rewrite of Bulk Audio Normalizer that makes it actually usable in production.

🔥 What's Changed

Before (v1.x): The application was extremely resource-intensive, error-prone, and frequently crashed during processing. It was essentially unusable for real-world audio normalization tasks.

Now (v2.0): Complete architectural overhaul resulting in a stable, efficient, and reliable audio normalization tool.

✨ Key Improvements

• Stable Processing: No more crashes during batch operations
• Efficient Resource Usage: Dramatically reduced memory and CPU consumption
• Reliable Operation: Processes complete successfully without errors
• Modern UI: Built with pywebview for native desktop integration
• Professional Build: Properly bundled FFmpeg binaries for both platforms
