Minutes (needs refinement)
Synchronizing from last weeks' status:
- Wassim: How do you customize Android to one product. how to properly connect them with Android? We presented some codes and discussed how they can help, what are your impressions?
- Piotr: Audio Weaver was specially a quite interesting topic and it seems wiedly used.
- Wassim: you can use Audio Weaver for free with https://elinux.org/R-Car/Boards/M3SK development kit
- Wassim: you can use it on PC but it's based on Matlab
- Wassim: the goal is the smooth transition between the demo/emulation, and the product. Concept is requirement as product model.
- In the future a researcher would just for example provide an effect model and this would be a requirement to the suppliers
- Specially that we are using Android. We can have a ready Android system, and a ready effect model. What is left is to connect them.
- Wassim: this is the picture posted here Car Audio System Emulator. I'll take some time to create ppt Genivi slides
WebRTC / Trout
- Piotr: The trout project is using it controlling and image from Android
- Piotr: It's a nice audio solution. To have the effects controlled with a model and this is already implemented in the demo
- Piotr: In the end, we could have the WebRTC interface showing Audio coming out of Android and Effect controlled by the Audio Effect HAL and allows the user to apply additional effects on top of the effects.
- Wassim: yes and we could also have them decoupled: PC simulation where the decoupling happen but browser is GUI.
- Piotr: the question is about the LibPulse Audio
- Wassim: libpulse audio is simply a tool. What is more important is to show:
- if we have in the car many zones/speakers/etc.
- the user would see it on his browser the streams the channels etc.
- the user would choose what to listen to for example
- the architecture of the Car Audio System Emulator is independant of the PC but can be patched and used to control
- Pitor: further question: should the ECNR control interface should be exposed? and to what level are they exposed to?
- Wassim: as long as Android allows to do it, should be enough.
- Wassim: as long as something can be controlled from hardware, it should be controllable by software
- Wassim: imagine that every app has its own ECNR and multiple applications would need to run at the same time → this is why it's more interesting to have a system ECNR
- Pitor: common solutions don't utilize DSP firmware by default
- Piotr: if we talk about Trout , it's not an emulator, it's just an instance because most of the HAL will be virtualized. We are not connected to the pulse audio here for example. to keep with the same picture, we would do something different
- Wassim: completely okay, we don't have to use the pulseaudio server
- Piotr: we can forget about Alsa even, we don't need to rely on it, we can but we dont' have to because of the virtualization.
- Piotr: this virtualization would be seperate from browser and Alsa. ServiceVM openSynergy
- Piotr: android emulator - virtual android
- Gunnar: we would use here a virtual platform instead of virtualization
- Pitor link for trout and virtualization https://source.android.com/devices/automotive/virtualization
- Wassim: we didn't solve the control path yet
- between the android and browser how would you see that?
- audio control already implemetned in trout
- trout already has solutions for several audio control
- we need to look how easy it is to deply the grpc on the browser
- Wassim: question
- Piotr: for demonstration purpose, whatever is currently working
- Wassim: 3 demonstrations so far: raw audio with fload sample packets, Opus Codec, WebRTC not yet fully running but it's client 2 client (looking like an overkill)
- the audio connection is flexible and
- edit the diagram and the names and rework it and that should be the demo concept.
- audio weaver candidate for virtual effect platform, python audio effect but more work but open standard
gather some topics for next meeting to discuss about the 7th of may
webex is preffered as a meeting software. last time some people could not join (zoom) + possible to test it before hand
