Abstract
An ANR circuit, possibly of a personal ANR device and possibly within an ADC of the ANR circuit, feedback reference data, feedforward reference data and/or pass-through audio data is provided to a secondary downsampling (and/or decimating) filter and/or is provided to a calculating block (e.g., RMS or absolute calculation block) to derive side-chain data to be output by the ANR circuit to a processing device coupled to the ANR circuit to employ the side-chain data in an analysis related to the provision of feedback-based ANR, feedforward-based ANR and/or pass-through audio by the ANR circuit.
