Furthermore, it was the final build that loaded third-party VST plugins (like Izotope RX or Waves bundles) with absolute stability on Windows XP and Windows 7 32-bit.
Build 405 became the "golden master" for restoration houses. It was lightweight (installing in under 200 MB), launch time was ~2 seconds, and it never crashed during spectral analysis.

Technical Specifications File Format Support: WAV, MP3, WMA, AIFF, FLAC, and more.
Bit Depth: Supports up to 24-bit/32-bit (float) 192kHz audio. OS: Originally designed for Windows XP/Vista/7. A Note on Security and Licensing
When searching for or downloading legacy software in .rar format, always ensure you are sourcing files from a reputable archive.
