Minutes
Going through the presentation of Wassim
- The presentation is work in progress
- The main message is that we are extending the design of google and if there is something not supported by google, we try to make it common or standardized
- We need to decide on topics to discuss during the summit.
Summit next week discussion
- Unknown User (niskandar) : reorder the list of prioritized topics
- Piotr Krawczyk Unknown User (bartoszbialek) : could you please prepare the demo for the summit?
- Piotr Krawczyk Unknown User (bartoszbialek) : could you please prepare a few slides about the demo as well
- Wassim: Could the slides be finished before Wednesday evening in order to add them to the main presentation
- We have 4 slots:
- Introduction 30min: presentation of the AUDIO HAL + slides of demo + demo
- Slot 1, 45min: PoC details discussion, define Next Milstones (AM integration) (avoiding And modifications and long term API support strategies)
- Slot 2, 45min: PoC prerequisites (external raw streams, Injecting input streams)
- Slot 3, 45min: Going through the list and refining the priorities. Asking participants about their opinion and feedback
- Other topics:
Early Audio
Audio Calibration / Equalization
Controlling Audio Effects (Google might improve it in next version)
Unknown User (niskandar) : update that the investigation in the global effect was stopped because google will release new api
- Ruslan: We should not replace components of Android IMO. It's too expensive to maintain the components replaced.
- Wassim: Yes for sure we are trying to avoid component modification and trying to follow long term strategies of Android (by keeping up-to-date with where they are heading)

Updates of the tasks done from last week: Wassim, Piotr, Nadim
...
- Jaguar Land Rover (JLR) representatives working on Android Automotive joined the AASIG VHAL call this week and should join the All Hands monthly call next week. If they ever decide to join the Audio HAL project, we might have to think about the time of the meeting because they are based in the US Pacific
Project Status Report:- the Technical summit is nearly here, we must prepare a presentation about the projects VHAL and Audio HAL and in general update and prepare an agenda for the virtual meeting on the 14th of May.
- Unknown User (wassim.filali) : could you please work closely with Philippe and Gunnar in order to prepare a comprehensive technical report for the status of the project and an agenda?
- The Agenda can be found here https://www.eventleaf.com/geniviVTS. Some of the meetings are very interesting and will be broadcasted live by a professional company without the use of Zoom.
Gathered Todo's:
- Piotr Krawczyk : update of the PoC in AUDIO_HAL_CW18
- Unknown User (niskandar): create a picture for next week to show the different options of handling external streams in Android
- Unknown User (niskandar) : Check the list of list of prioritized topics and take care of updating it
- Unknown User (wassim.filali) : could you please work closely with Philippe and Gunnar in order to prepare an comprehensive technical report for the status of the project and an agenda?

- Discuss the gathered topics, who can work on which topics and which strategy
- Status update on the "access raw streams"
Minutes
Changes done in this page Android and System Level Audio:
...
- Piotr Krawczyk : please update the presentation attached
- 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.
Gathered Todo's:
- Unknown User (bartoszbialek) please add your comments in the page Android and System Level Audio
- Unknown User (wassim.filali) : please write down the decision about supporing the comrpession
- Unknown User (niskandar): investigate input steams as well from the page Android and System Level Audio
- Piotr Krawczyk : please update the presentation attached
- Gunnar Andersson: provide a place to add the code of the POC → android-external-audio-mixing repository
- @All: please check the topics of investigation to see if you would like to add more topics to the page Android and System Level Audio
- @All check your emails to see if you have received the invitation about the summit

...
- 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.
