MULTICHIP DYNAMIC RANGE ENHANCEMENT (DRE) AUDIO PROCESSING METHODS AND APPARATUSES

摘要

In accordance with embodiments of the present disclosure, a multichip circuit for processing audio signals having dynamic range enhancement information over two or more integrated circuits may include a host integrated circuit and a client integrated circuit. The host integrated circuit may be configured to determine a dynamic range enhancement gain for a digital audio input signal, process the digital audio input signal in accordance with the dynamic range enhancement gain, and transmit audio data based on the processed digital audio input signal. The client integrated circuit may be coupled to the host integrated circuit and may be configured to receive the audio data and wherein the client integrated circuit is provided with the dynamic range enhancement gain and the client integrated circuit is configured to process the audio data with the dynamic range enhancement gain.
