Abstract:
Systems and methods for limiting volume in an audio playback device using a feedback controller are disclosed herein. In one example, a gain stage modulates gain of an audio signal based in part on feedback from a downstream limiter. The gain stage receives a first audio signal as well as a feedback signal from the feedback controller. Based at least in part on the feedback signal from the feedback controller, the gain stage modulates a gain of the first audio signal to provide a second audio signal. The second audio signal is delivered to the limiter, which limits the second audio signal to produce an output signal. The output signal is played back via a transducer. The feedback controller receives a gain reduction value from the limiter and determines a feedback signal to provide to the gain stage upstream of the limiter.

Claim (Index 19):
The system of  claim 16 , wherein the TC filters comprise:\n a fast filter configured to suppress supra-threshold signals on a first timescale; an intermediate filter configured to suppress supra-threshold signals on a second timescale; and a slow filter configured to suppress supra-threshold signals on a third timescale, wherein the first timescale is less than the second timescale, and wherein the second timescale is less than the third timescale.
