No | Name | Description | Recommended solution (if you have) | Proposer |
---|---|---|---|---|
0(example) | When Car Navigation output Audio as high priority, current audio, e.g. multimeida needs tofaded out and then audio from Car navigation fades in | N/A | Toshiaki Isogai | |
Active source change | When user choose different audio source with current one, IVI system stop or pause current source and activate new one. | TBD | Toshiaki Isogai | |
Active source change | When user connect external device e.g. iPhone, USB memory IVI system change active source automatically to connected one. | TBD | Toshiaki Isogai | |
Active source management | When user disconnect external device which is currently audible, IVI system automatically disable it and change to next source. | TBD | Toshiaki Isogai | |
Active source locking | When user is in phone call, IVI restrict to change active source. | TBD | Toshiaki Isogai | |
Active sink change | When user connect external device e.g. Headphone current audio source will be automatically routed. | TBD | Toshiaki Isogai | |
Interrupt source mixing | When car close to cross road IVI system reduce the volume of current source and mix with interrupt source e.g. Navigation Guidance. | TBD | Toshiaki Isogai | |
Interrupt source mixing | When user start speech recognition, IVI system automatically reduce/mute the volume of current active source. | TBD | Toshiaki Isogai | |
Last source management | When user turn on engine, IVI system start playing the last remaining source. | TBD | Toshiaki Isogai | |
Start-up sound | During start-up sound, IVI system mute the last remaining source. | TBD | Toshiaki Isogai | |
Start-up sound | After start-up sound is completed, IVI system recover the volume of the last remaining source. | TBD | Toshiaki Isogai | |
Ending sound | When user stop the IVI system, it play ending sound. | TBD | Toshiaki Isogai | |
Ending sound | During ending sound is playing, the IVI system wait shutting down. | TBD | Toshiaki Isogai | |
Volume change | User can change the volume of active source or sink. | TBD | Toshiaki Isogai | |
Volume change | When user change volume during interruption e.g. Navigation Guidance, IVI system change its volume temporary or permanently. | TBD | Toshiaki Isogai | |
Mute/unmute | User can mute/unmute current active source. | TBD | Toshiaki Isogai | |
Volume normalization | IVI system normalize the volume between different sources. | TBD | Toshiaki Isogai | |
Volume management | When user change active source, IVI system mute/unmute to avoid distortion of sound. | TBD | Toshiaki Isogai | |
Volume acceleration | When road noise is increased by speed, IVI system automatically change the volume of active source. | TBD | Toshiaki Isogai | |
Fader/Balance control | User can configure the focus of volume in the location of car. | TBD | Toshiaki Isogai | |
Equalizer setting | User can change equalizer setting | TBD | Toshiaki Isogai | |
Sound Effect | Provide a capability of sound effect when changing sound stream, e.g. fade-in, fade-out and cross-fade | TBD | Tsuyoshi Sakamoto | |
Routing sound | System needs to route sound stream to proper zones. (driver zone, passenger zone, rear seat zone) | TBD | Tsuyoshi Sakamoto | |
Last Volume management | When user turn on engine, IVI system start playing the last remaining source with last Volume. | TBD | Naohiro Nishiguchi | |
Volume management | When vehicle detect moving objects and external ECU output sounds(e.g. Alert), IVI system mute(or reduce) volume of active source of IVI system | TBD | Naohiro Nishiguchi |
Ther are several Hardware architectures as presented by MAZDA in ALS 2017.
No | name | Description | AAAA | SoundManager based on GAM |
---|---|---|---|---|
0(example) | Nobuhiko Tanibata | A rule which is that fade-in/out of interrupt audio and current audio shall be defined with any toolkit. | N/A | N/A |
1 | Naohiro Nishiguchi | Shall be able to apply business logic implicitly. (*1) | Coverd | |
2 | Naohiro Nishiguchi | Shall have a persistency for sound source. | Coverd | |
3 | Naohiro Nishiguchi | Shall have a persistency for sound volume. | Coverd | |
4 | Naohiro Nishiguchi | Shall know all sound sources and sinks in IVI system. | Coverd | |
5 | Naohiro Nishiguchi | Shall manage sound route regardless of source and sink location. | Coverd | |
6 | Naohiro Nishiguchi | Shall manage volume regardless of the master of volume location. | Coverd | |
7 | Naohiro Nishiguchi | Shall be able to be used by application developper easily. | Coverd. ApplicationGuide is here | |
8 | Naohiro Nishiguchi | Shall be designed to support various kinds of communication protocols. e.g. MOST,CAN,,, | Coverd | |

Name | GENIVI Audio Manager |

Description | A framework for managing audio in an In-Vehicle Infotainment (IVI) context. |

Dependencies (not in AGL) | CommonAPI, Dlt logging, Persistence, Node-state-manager… (7) |
Name | Tizen PulseAudio Module (Murphy IVI) |
---|---|
Description | A native PulseAudio module using the Murphy policy manager along with the LUA scripting language to prioritize audio streams. |

Ecosystem | Tizen |
License | LGPLv2 |
Dependencies (not in AGL) | Murphy (1) |
Analysis | Murphy and LUA represent an unnecessary burden for an initial demo implementation; work-in-progress involves removing them for a simpler static logic. |
Name | Tizen PulseAudio Module (VConf) |
---|---|
Description | A native PulseAudio module using a static logic along with the VConf Tizen library to prioritize audio streams. |

Repository | Tizen Git |
Maintainer | Samsung (…@samsung.com) |
Ecosystem | Tizen |
License | LGPLv2.1 |
Dependencies (not in AGL) | VConf (1) |
Analysis | VConf represents an unnecessary burden for an initial demo implementation; the global logic does not seem feature-complete enough for above requirements, though. |
Manuel Bachmann is working on Tizen PulseAudio Module (Murphy IVI) to remove dependencies on Murphy and LUA, and provide a demo implementation fitting above requirements (2016/04/04).
Work can be followed here : https://github.com/Tarnyko/pulseaudio-module-murphy-ivi
(done so far : ported Tizen IVI PulseAudio 5.0 patches to AGL PulseAudio 6.0)
(planned for Week 23, June 9th 2016 : initial code sharing and demo)
