Title: Overhaul VST3 Processing & Multi-Threading Engine to Eliminate Audio Dropouts on High-End PCs

Adobe Audition needs a major architectural update in how its VST3 engine handles heavy 3rd-party processing queues.

I frequently experience severe audio dropouts, stuttering, and crackling during multitrack playback when using processor-intensive plugins, such as iZotope's Ozone Stem EQ or Cradle's The God Particle. For a long time, I assumed these playback issues were caused by my PC hardware. However, after upgrading to a top-tier, high-end PC, the exact same bottlenecks persist in Audition.

Meanwhile, running these exact same plugin chains across multiple tracks in other DAWs (like Reaper or Studio One) runs completely smooth on the exact same machine.

Dedicated DAWs handle heavy VST3 suites efficiently by using anticipatory dynamic buffering and balanced multi-core CPU scheduling. Audition's VST host engine appears to struggle with thread allocation and dynamic buffer delivery when loading complex real-time DSP processors on track and master inserts.

To keep Audition viable for modern audio production and mastering, Adobe needs to optimize VST3 multi-threading, refine host buffer handling, and prevent engine bottlenecks during multitrack playback.
