DSP Audio HAL Fiberdyne Systems https://github.com/fiberdyne/agl-4a-hal
Overview Understand vehicle audio setup Develop JSON configuration file
Vehicle Audio Setup Up to 15 speakers definitions available Configurable types through Engineering App Full Range, Mid Range, Tweet, SubWoofer options available
Configuration File Requires four main definitions: Hardware Zones Streams Controls
Hardware Define the card Channel Sinks Speaker definition, and port number Channel Sources
Zones Define groups of speakers, called Zones Map speaker to ordered audio input. Eg. FL / FR / RL / RR / C / SW
Streams Defines the sound DSP Sound Card devices Name/Role Profile Channels Zone
Controls Plugin exposes controls Configuration file defines additional control capabilities
Result Custom audio stream definitions Configurable audio routing
Result Custom audio stream definitions Configurable audio routing Control Parameters using ALSA
Result Custom audio stream definitions Configurable audio routing Control Parameters using ALSA Advanced Tuning and DSP capabilities
Going Forward Collaboration for reference mixer plugin Release ADSP Driver/Interface
