Apple Watch will be able to automatically control iPhone volume if a patent of Apple Lossless Audio CODEC (ALAC), will be implemented in the smart watch in the not too distant future, those from Cupertino describing the new technology in detail in its documentation.
According to those from Apple Watch will be able to control iPhone volume so that the terminal plays iOS alerts louder or slower depending on the ambient noise in the location where we are, the adjustment being made without the iPhone being touched by us.
Although Apple Lossless Audio CODEC (ALAC), does not describe the method by which it would implement this functionality, we are most likely talking about one or more microphones that will be available in the watch and will record the noise level around us.
Apple Watch already has a microphone to allow making phone calls, but it will be necessary to implement one more, or maybe even two more to be able to correctly measure the noise level around a user's location.
A desired alert volume can differ dramatically based on whether a user is in his office with his device on his desk or in a crowded subway with his device in his pocket. Despite these distinct preferences, a user can keep an alert volume fixed in order to avoid the inconvenience of changing the setting or due to forgetfulness. A wearable device is likely to be relatively exposed to the ambient air while it is being worn, while a host device might be exposed to ambient air or shielded to varying degrees from ambient air by a sonic "barrier," depending on how it is being carried or stowed.
The noises recorded by the Apple Watch could be corroborated with noise data also taken by the iPhone, and the volume level of the smartphone will be adjusted accordingly so that the alerts received are not heard very loudly.
In the same way, the volume of the personal assistant Siri could be automatically adjusted according to the level of ambient noises, so that users can have the best possible experience.
Other comparisons of sound can be used for other purposes, such as adjusting speech detection algorithms in the host device to account for environmental sounds that may interfere with speech detection.
Given that we are talking about a patent, no one knows when or if it will ever be implemented in an iPhone, so it remains to be seen what Apple's plans will be for the future.
