Overview
- The audioOS 27 beta 8 code revealed Friday shows Apple is testing a four‑HomePod surround layout that assigns front‑left, front‑right, rear‑left and rear‑right roles.
- The files name surround processing features such as automatic room calibration, dialogue enhancement, bass management, timing corrections and separate processing modes for movies and music.
- A new Party Mode for stereo‑paired HomePods appears in the code and is designed to create a diffuse, room‑filling soundfield instead of a single sweet spot.
- The code references an internal tuning system called “Forklift” and an unknown hardware family labeled AID12007, which suggests rear channels or full functionality could require an unreleased HomePod model.
- There is no user setup in the Home app or Apple TV today and Apple has not announced availability, so the features should be treated as internal tests that may be delayed or tied to future hardware releases.
