Abstract
Personal audio systems and methods are disclosed. The personal audio system includes a processor configured to generate a processed ambient audio stream by processing the ambient audio stream in accordance with a selected set of processing parameters selected from the plurality of processing parameter sets stored in the memory, a communications interface configured to receive a new set of processing parameters, selected by someone other than the user, and a controller configured to instruct the processor to begin generating the processed ambient audio stream by using the new set of processing parameters.
Claims20
A personal audio system, comprising:
- a housing configured to interface with a user's ear;
- an input subsystem disposed within the housing and comprising a microphone, a preamplifier and an analog to digital converter coupled to one another, the input subsystem configured to convert ambient sound into an ambient audio stream;
- a memory storing data defining a plurality of processing parameter sets, wherein each of the plurality of processing parameter sets is associated with a combination of at least one of a corresponding location, a corresponding ambient sound profile, and a corresponding context;
- a processor disposed within the housing and coupled to the input subsystem, the processor configured to generate a processed ambient audio stream by processing the ambient audio stream in accordance with a selected set of processing parameters selected from the plurality of processing parameter sets stored in the memory;
- a geo-locator configured to determine a current location of the personal audio system;
- a controller, in communication with the processor, wherein the controller is configured to determine a current ambient sound profile by extracting feature data from the ambient audio stream, wherein the controller is configured to determine a current context according to a user selection, wherein the controller is configured to select the selected set of processing parameters according to the current location, the current ambient sound profile, and the current context, and wherein the controller is configured to instruct the processor to begin generating the processed ambient audio stream by using the selected set of processing parameters;
- and
- an output subsystem disposed within the housing and coupled to the processor, the output subsystem comprising a digital to analog converter, an amplifier and a speaker coupled to one another, the output subsystem configured to convert the processed ambient audio stream into processed output sound for the user's ear.

A method of processing ambient sound in a personal audio system, the method comprising:
- converting ambient sound into an ambient audio stream using an input subsystem disposed within a housing and comprising a microphone, a preamplifier and an analog to digital converter coupled to one another;
- storing data, in a memory, the data defining a plurality of processing parameter sets, wherein each of the plurality of processing parameter sets is associated with a combination of at least one of a corresponding location, a corresponding ambient sound profile, and a corresponding context;
- generating a processed ambient audio stream by using a processor disposed within a housing and coupled to the input subsystem to process the ambient audio stream in accordance with a selected set of processing parameters selected from the plurality of processing parameter sets stored in the memory;
- determining, using a geo-locator, a current location of the personal audio system;
- determining, by a controller, a current ambient sound profile by extracting feature data from the ambient audio stream;
- determining, by the controller, a current context according to a user selection;
- selecting, by the controller, the selected set of processing parameters according to the current location, the current ambient sound profile, and the current context;
- instructing, by the controller, the processor to begin generating the processed ambient audio stream by using the selected set of processing parameters;
- and
- converting the processed ambient audio stream into processed output sound for a user's ear using an output subsystem disposed within the housing and coupled to the processor, the output subsystem comprising a digital to analog converter, an amplifier and a speaker coupled to one another.
