Concept

desktop proxy and device parity

The exact phone engine also runs on a Mac for fast testing; real phones confirmed that the Mac gives the same judged quality.

From the record

In technical terms: Same engine code and tree hash on desktop and phone; parity on v0.1: 12 GB-class phone 0.529 = desktop 0.529 (Haiku); 8 GB phone 0.561 vs 0.558/0.560 (Opus).
