Codec Abstraction Architecture

This directory contains abstractions and adapters for various hardware and software audio codecs.

Overview

Provides a unified interface to initialize, configure, and stream data to/from codec dependencies.

Configuration and Scripts

  • Kconfig: Specifically manages configurations for external codecs. For example, it defines options for the DTS_CODEC, including a testing/CI stub DTS_CODEC_STUB when COMP_STUBS is enabled. Use of the actual DTS codec requires a pre-compiled static library from Xperi.
  • CMakeLists.txt: Specifies Zephyr build integration. For the DTS codec, it checks for modular builds (llext). If built statically, it either links the stub source or imports the pre-compiled libdts-sof-interface-i32.a library depending on configuration.
  • Topology (.conf): tools/topology/topology2/include/components/dts.conf defines the dts widget. It exposes cpc (cycles per chunk) and configures a byte control of size 2048 with extctl operations. Defaults to UUID 4f:c3:5f:d9:0f:37:c7:4a:bc:86:bf:dc:5b:e2:41:e6.
