Abstract
The disclosure pertains to an audio signal processing system that offers low latency without sacrificing various desirable features such as large dynamic operating range and low power consumption. Low latency is achieved by generating a feed-forward signal that is based in part on performing high-pass filtering and threshold crossing detection upon an amplified transducer signal. The feed-forward signal is provided to a controller, which uses the feed-forward signal to produce a feedback signal that controls one or more operating parameters of one or more components of the audio signal processing system. The feedback signal produced in this manner avoids incurring a delay associated with propagating the amplified transducer signal to the controller via an analog-to-digital converter (ADC) for purposes of generating the feedback signal. Generation, and use, of the feed-forward signal also allows the audio amplifier to rapidly adjust to amplitude changes in audio signals received from the transducer.
