[uwp] background recording RRS feed

  • Question

  • Hi,

    I was wandering, how come it is not possible to record audio on the background on a p.c. or laptop but the uwp microsoft voice recording app can? It records while minimalized, it records during a screensaver and records while the screen switches to off. The app can even keep the computer from entering sleep mode.I have tested it on a p.c. and two laptops.

    I thought background recording wasn’t possible or just for an x-amount of seconds? Which confirms when I run my own app. When it is minimalized recording is muted, when the screensaver comes on then recording is muted. When the screen gets shut down then sometimes it records a bit of sound, less than a second, and then the recording is muted again.

    I hope you have somebody can explain what is happening here.

  • Hello,

    If you open its manifest then you will see following 

            <uap:Extension Category="windows.protocol">
              <uap:Protocol Name="ms-callrecording">
            <uap:Extension Category="windows.fileTypeAssociation">
              <uap:FileTypeAssociation Name="m4a">
            <Extension Category="windows.backgroundTasks" EntryPoint="BackgroundAudio.BackgroundAudioTask">
                <Task Type="audio"/>
        <uap:Capability Name="documentsLibrary"/>
        <uap:Capability Name="contacts"/>
        <mobile:Capability Name="recordedCallsFolder"/>
        <rescap:Capability Name="extendedExecutionBackgroundAudio"/>
        <rescap:Capability Name="backgroundMediaRecording"/>
        <DeviceCapability Name="microphone"/>

    and I think the solution is in "extendedExecutionBackgroundAudio" capability.

  • Hello Azat,

    You might be correct on the restricted capability. I’ve learned that these capabilities are only available to microsoft and partners. I’m not a partner so I think background audio recording will be a no go for uwp.

    Thank you for responding.

  • Hello, 

    If you don't want to upload app to the store then you can declare this capability in manifest and use side loading for app installation without any problem.
