Abstract: A system and method for storing data samples in discrete poses and recalling the stored data samples for updating a sound filter. The system determines that a microphone array at a first time period is in a first discrete pose of a plurality of discrete poses, wherein the plurality of discrete poses discretizes a pose space. The pose space includes at least an orientation component and may further include a translation component. The system retrieves one or more historical data samples associated with the first discrete pose, generated from sound captured by the microphone array before the first time period, and stored in a memory cache (e.g., for memorization). The system updates a sound filter for the first discrete pose using the retrieved one or more historical data samples. The system generates and presents audio content using the updated sound filter.

Abstract: A conference terminal and a feedback suppression method are provided. In the method, a transmitting sound signal is divided into sub sound signals of multiple frequency bands. Different sub sound signals correspond to different frequency bands. An interfered frequency band corresponding to the howling interference is detected according to the sub sound signals of those frequency bands. The power of the sub sound signal of the interfered frequency band increases along with time. The interfered frequency band is affected by the howling interference. An interference direction is determined according to multiple input sound signals received by the microphone array and merely pass through the interfered frequency band. A sound from the interference direction leads to the howling interference. A beam pattern of the microphone array is determined according to the interference direction. The gain of the beam pattern in the interference direction is reduced.

Abstract: Techniques for implementing an augmented audio conditioning (AAC) system are described herein. In some examples, the AAC system can store conditioning data comprising crowd noise experiences associated with context-relevant environments and/or actions associated with an activity. The AAC system can detect an action of a user who is training in a conditioning environment and determine that the action is associated with the activity. In some examples, the AAC system can also determine an association between the action of the user and audio data representing a crowd noise experience of a context-relevant environment during an event. Furthermore, the AAC system can, in response to detecting the action of the user, output the audio-conditioning data into the conditioning environment to simulate the crowd noise experience of the context-relevant environment during the event.
