[Release Candidate] Dolby Atmos™

• Dolby Atmos™ Digital Signal Processer with effects and Graphic User Interface ported from the latest ZTE™ Axon 7 Android Oreo firmware intended for all Android devices on Android Oreo.
  
  
• Dolby Atmos™ sound effects applied to media audio output supporting various media players.
  
  
• Flexible custom recovery installation archive supporting Magisk and SuperSU installations as well as existing audio mod installations - fully supporting Enforcing SELinux Mode:
  
  
  • Multiple installation scenarios available using the included arise_parameters.prop that is automatically copied to /sdcard if not already there. When edited by the user in this /sdcard location, arise_parameters.prop can:
    
    
    • Instruct an installation directly to /system if a Magisk user prefers a /system installation over the Magisk module installation.
      
      
    • Instruct a system-less module installation using /su if a SuperSU user with the system-less SuperSU installation prefers a module installation for a variety of reasons such as insufficient /system space to accommodate a /system installation or the convenience of a persistent installation unaffected by rom updates.
  
  
• An independent build maintained by @[B]Zackptg5[/B] fully integrated with Unity:
  
  
  • Active accommodation of existing and future Magisk modules relevant to audio modification.
    
    
  • Flashing the installation archive over a current installation results with an uninstallation of the Dolby Atmos™ Magisk module.
    
    
  • @[B]Zackptg5[/B] explains the nuances a bit further here.

• A minimum of SDK 26 (Android 8.0) is required for installation to begin, else Exit 1 will abort the recovery installation activity.
  
  
• A root solution or a capable kernel is required in order to automate the execution of scripts during boot to allow the appropriate sepolicy rules necessary for Dolby Atmos™ functionality while in Enforcing SELinux mode.
  
  
• Third party audio effects and DSP's such as ViPER4Android (<--
  link to @[B]docnok63[/B]'s solution :highfive may require some extra effort to allow processing due to Dolby Atmos' dependency on its output_session_processing music effect.

• Performing a backup of the /system partition in recovery is encouraged for users receiving a /system installation:
  
  
  • 
    TWRP > Backup > Check System > Edit name, if desired > Swipe to perform backup operation
  
  
• Confirm device requirements are met and installation results are acceptable.
  
  
• Confirm an escape route is available in the event of unsuccessful device boot or unsatisfactory experience.
  
  
• Confirm successful download and location of downloaded archive(s).
  
  
• Boot to recovery > Install > *.zip > Swipe to perform installation operation > Advanced > Copy Log > Reboot
  
  
• Updating procedure is no different unless specified otherwise.

• Android File Host (gh)

• @[B]ahrion[/B] & @[B]Zackptg5[/B] for Unity

• Purpose and Contribution:
  
  
  • Introduced with Android Nougat, audioserver appears as its own binary after years of being a component of /system/bin/mediaserver in all Android firmware.
    
  • Introduced with Android Nougat, vendor provided Dolby Atmos™ software audio solutions appear with a new media.dolby_memoryservice that is compiled into /system/bin/audioserver as well as a unique system library typically appearing as /system/vendor/lib/libdlbmemoryservice.so.
    
  • These new components are crucial to a functional Dolby Atmos software solution and there is currently no known way of achieving any amount of success without them.
    
  • While porting the very first Nougat Dolby Atmos system available, courtesy of ZTE™ Axon 7’s initial Nougat firmware image, I discovered this implementation and a functional port was finally available.
    
  • However, using a Nexus 6 at the time, I was able to evade nearly all bootloop scenarios with much of what would cause a bootloop scenario for others.
    
  • It took no time to determine that this new media.dolby_memoryservice component was going to be a challenge in achieving a viable Dolby Atmos Nougat port.
    
  • To begin, results were determined: Successful device boot or Unsuccessful device boot.
    
  • Stock firmware seemed to fare much better than custom firmware, even for just a single device.
    
  • A pattern began to emerge for me when focusing only on the audioserver binary: Stock firmware had an audioserver file size range (21.50KB-21.53KB) and Custom firmware had an audioserver file size range of its own (21.58KB-21.60KB).
    
  • Not a significant difference, unless you were looking for a difference.
    
  • This assessment presented an effective predictibility of an installation scenario's success and failure with nearly 100% accuracy (nearly only because every possible scenario is not documented).
    
  • This audioserver database is intended for those that have determined a single scenario as successful or as unsuccessful due to the native audioserver binary in their device’s rom being overwritten or symlinked over with the audioserver native to the ZTE™ Axon 7 Oreo firmware AND NOT A RESULT OF ANY OTHER FILE OR SCRIPT OPERATION!!
    
  • Simply, those with success have the easier path requiring nearly no effort other than uploading the native audioserver from their firmware along with the firmware build.prop to the WIN audioserver folder.
    
  • Those contributing to the FAIL audioserver folder with the native audioserver along with the firmware build.prop will only be able to do so after some personal testing to ensure the audioserver switching is the exclusive cause of an unsuccessful device boot after flashing the Dolby Atmos installation archive in recovery.

I really had to! Always keeping My Eyes open for cool new Android Stuff like that here. :good:
Well, i got stuck on the Dolby Atmos Print with TWRP 3.2.1.0 but i will give it a try again after cleaning and updating up My Device. I was about to Port over the latest Sony Oreo Enhancements but there are a lot of crazy changes compared to Nougat and older Firmwares. Given up after some Hours of researching and forking the XZ Premium Oreo Firmwares. Dolby Atmos Oreo looks also really promising, hope i get at least that running on My Axon...

Think i've to PM You for more, don't want to go to OT here
