Abstract
A combined ambient sound and secondary audio system comprises at least one microphone for receiving ambient sound, at least one receiver for receiving secondary audio from a secondary audio source not audible in the ambient sound. The system further includes a memory storing one or more sets processing parameters comprising instructions for processing the ambient sound and the secondary audio and a processor coupled to the memory, the microphone, and the receiver configured to generate combined ambient and secondary sound by combining the ambient sound and the secondary audio as directed by a selected set of processing parameters retrieved from the memory.
