Brief statement of the problem(s) on which the group worked:
In the future the full acoustic spectrum is required for new use cases that require non-traditional sound. Some examples of this include:
Developments in transducers have unlocked new use cases beyond traditional acoustics. These unlocked feature sets struggle to be implemented seamlessly.
How is the data from these multiple components formatted and packetized:
Therefore, there is a need for aggregation of data from multiple components, some of which are not audio specific, while at the same time some traditional audio components are being used for non-audio applications.
A brief statement of the group’s solutions to those problems:
It was decided that it was better to “turn things upside down” by identifying problems to highlight to the industry the areas that need to be addressed.
The following are some meaningful terms that we used in this report and to allow communication in a consistent and understandable fashion:
The focus of this report is on the non traditional sounds and processing to ensure that it does not negatively impact traditional audio.
Expanded problem statement:
The full acoustic spectrum is required for new use cases that require non-traditional sound. There is an insular market dynamic which is prohibiting innovation and adoption of enhanced usage of existing transducer and interface capabilities. Every stage of the existing architecture faces problems addressing this new paradigm, some of which are identified below:
Transducer interfaces (analog, PDM, I2S):
SoC, Application, Cloud interfaces:
Multi-device collaboration across the signal chain hierarchy (transducer, SoC, app):
Architectural knowledge about the non traditional sound processing:
Closed ecosystems that only support traditional audio:
