An audio processing method, comprising: receiving, by a control system and via an interface system, a content stream that includes input audio data; applying, by the control system, a multiband limiter to the audio data or to a processed version of the audio data, to produce multi band limited audio data; determining whether the multiband limited audio data would cause one or more audio reproduction transducers of an audio environment to operate outside a linear range when played back over the one or more audio reproduction transducers; controlling, by the control system, an update of one or more filter coefficients by an acoustic echo canceller or an update of a noise estimate by a noise estimator based upon the determination whether the multi band limited audio data would cause the one or more audio reproduction transducers of the audio environment to operate outside the linear range; and providing the multi band limited audio data to the one or more audio reproduction transducers of the audio environment; wherein controlling an update of the one or more filter coefficients by the acoustic echo canceller involves controlling the acoustic echo canceller to not update the one or more filter coefficients if the multi band limited audio data would cause the one or more audio reproduction transducers of the audio environment to operate outside the linear range; and wherein controlling an update of the noise estimate by the noise estimator involves controlling the noise estimator to not provide updated noise estimates if the multi band limited audio data would cause the one or more audio reproduction transducers of the audio environment to operate outside the linear range. receiving, by a control system and via an interface system, a content stream that includes input audio data; applying, by the control system, a multiband limiter to the audio data or to a processed version of the audio data, to produce multi band limited audio data; determining whether the multiband limited audio data would cause one or more audio reproduction transducers of an audio environment to operate outside a linear range when played back over the one or more audio reproduction transducers; controlling, by the control system, an update of one or more filter coefficients by an acoustic echo canceller or an update of a noise estimate by a noise estimator based upon the determination whether the multi band limited audio data would cause the one or more audio reproduction transducers of the audio environment to operate outside the linear range; and providing the multi band limited audio data to the one or more audio reproduction transducers of the audio environment; wherein controlling an update of the one or more filter coefficients by the acoustic echo canceller involves controlling the acoustic echo canceller to not update the one or more filter coefficients if the multi band limited audio data would cause the one or more audio reproduction transducers of the audio environment to operate outside the linear range; and wherein controlling an update of the noise estimate by the noise estimator involves controlling the noise estimator to not provide updated noise estimates if the multi band limited audio data would cause the one or more audio reproduction transducers of the audio environment to operate outside the linear range.
