- Piotr:Stage 1 of the POC should be finished next week
- Gunnar Andersson: provide a place to add the code of the POC
DONE → 2020-04-20: android-external-audio-mixing repository
- Gunnar Andersson: provide a place to add the code of the POC
- Piotr: the concept is that we can either
- Create a separate framework parallel to the android framework that takes care of accessing devices. Any application that is aware of such a framwork can use it in order to better control the streams.
- Or use the framework to create many devices and connect them as needed.
- Gunnar: this is also nice for systems with different OS
- Piotr: there is still one point of investigation
- the Android Audio API, the one created to allow low latency streams. we have to think how we would handle this.

...
- Slides from Wassim about the two models inside and outside of AA
- discussion of the cases/features that we are trying to solve
- checking the Audio Manager to decide whether or not it needs an update
Minutes
- 2 strategies or options:
- android provides sources and sinks
- Android controls the complete systems
- We will not discuss the need to have such options
- Basically some functions cannot be integrated to AA
- Audio sources coming from android or from external (android not aware of them)
- Each strategy has limitations and can be criticized
- Idea is to get each model and apply to it questions/cases
- Questions like safety sources, raw streams, etc.
