Introduction from Philippe
- Have a look at the detail from Jira and update the tickets
- Check the meeting in May - Virtual all members meeting
- 4th of May until the 7th of May: starting to gather/fill the content. Provide an introduction and demonstration of particular topics
Jira going through the Audio HAL board
- AASIG-70: needs a bit more time (a couple of days)
...
- to be updated.
- AASIG-75: Design is in progress but there are more relevant questions first
- What is the expectation here? we were still with the emulator idea? What is the purpose of this ticket?
- Detailed discussion
- Communication between the host and the emulator
- Projected mode and Media Sync Service
- Networking between host and emulator
- ECNR - Echo Cancellation and Noise Reduction - before or after HAL
- Can be used in bare-metal Android solution, Also Android AEC
- Summary, 2 different points
- Own Microphone to Android: goes through Audio HAL
- External Microphone to Android: this can go through the "custom sync service" → offloading topic
- AASIG-92: we studied it and we understood that we need an AVB stack or A2B but do we do more investigating here?
- AASIG-104: Wassim's opinion x86 is real heardware and this for now fully okay instead of targeting a hardware because anyway the target hardware chosen here will not be used in the car
- News about the hardware lab: There are functional boards with RENESAS
- This might be interesting when we pick up the topic of the audio latency
- removed from the sprint
- For the Virtual All Members Meeting
- Idea from Piotr will be first analyzed by Piotr and then presented in the next week

Discussion about

...
- audio transfer to external ECU
- There are still some problems with the definition of Offloading
- There are some overlapping and similartiessimilarities
- There is still a question of considering the Audio HAL as part of Android or not
- The way you control your dsp on the Audio HAL is completely outside of Android
- Piotr maybe meant that since we decided that the audio effect Audio HAL is outside of Android, what are the APIs that we can interact with
- Any android has Audio HAL implementation but the different is that the audio effect HAL expects the audio to be back (not like an amplifier where the audio is just leaving Android and not returning)
- also a good defenition definition of Offloading would help
- implement Input
- implement Raw Stream extraction

- 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.
