Abstract
Personal audio systems and methods are disclosed. A personal audio system includes a processor to generate a personal audio stream by processing an ambient audio stream in accordance with an active processing parameter set, a circular buffer memory to store a most recent snippet of the ambient audio stream, and an event detector to detect a trigger event. In response to detection of the trigger event, a controller may extract audio feature data from the most recent snippet of the ambient audio stream and transmit the audio feature data and associated metadata to a knowledgebase remote from the personal audio system.
Claims20
A system, comprising:
- a memory;
- and
- a processor configured to:
- receive audio feature data and associated metadata from a personal audio system, wherein the audio feature data is extracted from a most recent snippet of an ambient audio stream;
- analyze the audio feature data and the associated metadata;
- develop a current ambient sound profile based, at least in part, on the audio feature data;
- develop a new processing parameter set based, at least in part, on the current ambient sound profile, the new processing parameter set indicating a type and degree of one or more processes to be performed on the ambient audio stream;
- provide the new processing parameter set to the personal audio system;
- and
- cause the memory to store the new processing parameter set and the current ambient sound profile.
A method, comprising:
- receiving audio feature data and associated metadata from a personal audio system, wherein the audio feature data is extracted from a most recent snippet of an ambient audio stream;
- analyzing the audio feature data and the associated metadata;
- developing a current ambient sound profile based, at least in part, on the audio feature data;
- developing a new processing parameter set based, at least in part, on the current ambient sound profile, the new processing parameter set indicating a type and degree of one or more processes to be performed on the ambient audio stream;
- and
- providing the new processing parameter set to the personal audio system.
One or more non-transitory media having software stored thereon, the software including instructions for controlling one or more devices for:
- receiving audio feature data and associated metadata from a personal audio system, wherein the audio feature data is extracted from a most recent snippet of an ambient audio stream;
- analyzing the audio feature data and the associated metadata;
- developing a current ambient sound profile based, at least in part, on the audio feature data;
- developing a new processing parameter set based, at least in part, on the current ambient sound profile, the new processing parameter set indicating a type and degree of one or more processes to be performed on the ambient audio stream;
- and
- providing the new processing parameter set to the personal audio system.
