Code found in the beta version of audioOS 27 suggests that Apple might be working on a more advanced audio system for its HomePod smart speakers. The code hints at the development of a four-speaker surround system, where two speakers would be positioned behind the listener, in addition to the usual two in front. This setup would allow users to arrange up to four HomePod 2 units—two in front and two in the back—creating a more immersive listening experience. This would mark a major upgrade from the current HomePod configuration, which typically supports only two units in a stereo pair connected to an Apple TV. The code also includes features like automatic room calibration, which adjusts audio output based on the physical space, and speaker position detection, which identifies where each unit is placed. Other features include synchronization of multiple speakers, bass management to optimize low-frequency sound, equalization for better sound quality, and enhancements to make dialogue in movies and shows clearer. Additionally, the system appears to use different audio processing techniques depending on the type of content being played—automatically adjusting how sound is distributed across four HomePod units or limiting it to two front speakers in stereo mode. Another feature mentioned in the code is called Party Mode. This mode is designed to expand the sound field for HomePod units used in stereo pairs, helping to fill a room more evenly and allowing for better listening experiences from multiple locations. The code also references a system named Forklift, which would combine two HomePod 2 units with two other devices that use an unspecified hardware model called AID12007. This could point to the development of a future HomePod mini 2, a HomePod 3, or another new audio product from Apple. While these features are not expected to be officially announced at Apple’s upcoming event, their presence in the code suggests the company is actively testing them. Reports also indicate that Bloomberg has previously suggested the arrival of a new HomePod mini, a new Apple TV, and a new hub for the connected home. These updates could help Apple strengthen its home cinema ecosystem, offering users a more integrated and immersive audio experience.
