I am creating an application using Unity and MRTK to subtitle the audio of people around me with HoloLens2.
But there is a problem, I can get the sound of my own voice well with the HoloLens2 built-in microphone, but I cannot get the sound of the surroundings well with the HoloLens2 built-in microphone.

Hello,
I don't know how to use it.Mixed Reality Toolkit Microphone Stream Selector. I want to set the microphone setting to "room capture"
Please check out this Unity sample script: LINK. It shows how to use the raw data from the microphone and also how to record wav files. You can change the MicStream.StreamCategory to MicStream.StreamCategory.ROOM_CAPTURE at line 14.
Please also double check this README doc: Microphone Stream Selector
Thanks for the reply!
I tried micstreamdemo.cs but I am not sure.
Can I do this Demo while using Mixed Reality Toolkit 2.7.2 which I am using for HoloLens2 development?
First, what Package should I import into my Unity 2020.3.11f application to try Micstreamdemo.cs?

To use Microphone Stream Selector, you need to build the solution first, and then contain the DLL file into MicStreamSelector/UnityAddon/Plugins/UWP/ARM64/ and add MixedRealityToolkit/Input/MicStreamSelector folder to your Unity project. After that, you can try to import all the types from Microsoft.MixedReality.Toolkit.Audio namespace by using directive and invoke the function from WindowsMicrophoneStream.cs.

Hernando, I have the same problem. I installed StreamSelector via MRTK (version 1.0.0) but the MRTK sample keeps giving me a "Assets\Samples\Mixed Reality Toolkit Examples\2.8.2\Demos - Audio\Scripts\MicrophoneAmplitudeDemo.cs(37,17): error CS0246: The type or namespace name 'WindowsMicrophoneStream' could not be found (are you missing a using directive or an assembly reference?)" Any idea why?

Hi FranklinChen!
I tried running those Unity samples on the Hololens 1 - they work in the Unity editor, but when building for the HL1 in Visual Studio 2017, it throws this runtime error:
The value of the ESP was not properly saved across a function call. This is usually a result of calling a function with one calling convention with a function pointer declared with a different convention
Any clues what this could be? I saw a couple sort of related issues in the MRTK github, but the solutions don't seem to have any effect.
EDIT:I got it working by manually changing the calling convention to Cdecl in the dll imports - but now I'm getting a WinRT access denied error.

Hello Hernando, could you guide me in setting up the Microphone Stream Selector for MRTK 2.8.2 in Unity 2019.4.16f1? I am new to the HL App development part and not sure which solution needs to be built and how I should add it to the unity folder. Also, where can I find this solution file? Any pointers in this regards would be really helpful. Thanks in advance for your time!
