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 1):
A method, comprising:\n receiving a first audio signal at a gain stage upstream from a limiter; receiving a feedback signal from a controller at the gain stage; based at least in part on the feedback signal from the controller, modulating a gain of the first audio signal via the gain stage to provide a second audio signal; receiving the second audio signal a the limiter downstream of the gain state; limiting the second audio signal via the limiter to produce an output signal; providing a gain reduction value from the limiter to the controller; based on the gain reduction value from the limiter, determining the feedback signal via the controller; and playing back audio based on the output signal.
