One of the main features of the recently introduced Sony controller for PS5 became a built-in microphone, allowing players to connect to sound chat instantly, without wasting time looking for a headset.
“DualSense is equipped with a built-in microphone system so that players can quickly engage in a conversation without a headset,” the company briefly outlined their vision on the PlayStation Blog, without focusing on the technology used.
Nevertheless, thanks to it, the controller really has many features.
SegementNext employees have discovered a patent that clarifies some of the details. The document was submitted for consideration in February, and was released only this Monday. It says that there are at least three microphones inside DualSense. They work together to maximize isolation and suppress noise around the player. Multiple microphones work like a human ear – they determine the position of sound in space, analyzing the time during which vibrations reach the hearing organs.
Excerpt from patent text:
“Three or more microphones included in the array allow you to determine the location of the sound source relative to the microphones, the distance to which can be calculated based on the time in which the sound reaches each of the microphones.
In addition, captured sound can be processed to exclude sounds that do not belong to a specific area of the interactive environment. ”
SegementNext notes that the patent also refers to the operation of the technology when using the controller by multiple users. For example, the fact that the array of microphones built into DualSense eliminates the crosstalk coming from other players and DualSense microphone arrays.
“When multiple controllers are used, the audio data received from them can be analyzed in combination, together with the location and orientation of the controllers, to enable accurate positioning of sound in space.”
The release of DualSense is scheduled for the end of 2023 along with the PlayStation 5.
