Embodiment Construction

[0029]Embodiments of the present disclosure may provide processing of audio signals with dynamic range enhanced ("DRE") data / information between at least two or more integrated circuits ("ICs"). Audio signals with DRE data / information can be processed such that communication between two or more ICs can be done digitally (eg, digital communication between two or more ICs). The DRE data / information of the audio signal can be provided to two or more ICs. Various methods of providing DRE data / information to an IC may be provided in embodiments of the present disclosure. Other data or information, such as Adaptive Noise Cancellation ("ANC") data or information, may also be provided or processed and also communicated digitally between the two or more ICs. An advantage of embodiments of the present disclosure may be to eliminate or reduce analog communication between two or more devices that process and / or transmit audio signals, and instead provide digital communication between two...

Abstract

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 includea 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 coupledto 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.

Description

[0001] Related Application Cross Reference [0002] This disclosure claims priority to U.S. Nonprovisional Patent Application Serial No. 14 / 975015, filed December 18, 2015, which claims U.S. Provisional Patent Application Serial No. 14 / 975015, filed March 27, 2015 Priority of Serial No. 62 / 139123, both cases are hereby incorporated by reference in their entirety. technical field [0003] The field of representative embodiments of the present disclosure relates to audio processing methods, devices or tools, and more particularly, to multi-chip dynamic range enhancement ("DRE") audio processing methods, devices and tools. Background technique [0004] Audio processing methods, apparatus, and tools for processing digital audio input signals into analog audio output signals may be implemented or provided on a single integrated circuit ("IC") and include features for enhancing audio signals processed by the single IC Method(s) of dynamic range (eg, Dynamic Range Enhancement ("DR...
