Claim:
1. A personal audio system, comprising: a housing; a microphone, a preamplifier, and an analog to digital converter to convert ambient sound into an ambient audio stream; a processor to generate a personal audio stream by processing the ambient audio stream in accordance with an active processing parameter set, wherein the active processing parameter set indicates a type and degree of one or more processes to be performed on the ambient audio stream to modify a manner in which a user of the personal audio system hears the ambient audio stream, wherein the personal audio stream is a modified version of the ambient audio stream; a buffer memory to store a most recent snippet of the ambient audio stream; an event detector to detect a trigger event from a set of trigger events, wherein at least one of the trigger events indicates or causes a change in the active processing parameter set; and a controller configured to, in response to detection of the at least one of the trigger events, upload from the buffer memory the most recent snippet of the ambient audio stream and associated metadata to a knowledgebase remote from the personal audio system, wherein the knowledgebase remote from the personal audio system analyzes the most recent snippet of the ambient audio stream, wherein the most recent snippet of the ambient audio stream comprises a duration of the ambient audio stream that occurs immediately preceding the trigger event; and a digital to analog converter, an amplifier, and a speaker to convert the personal audio stream into personal output sound, wherein the microphone, the preamplifier, the analog to digital converter, the processor, the digital to analog converter, the amplifier, and the speaker are disposed within the housing.
