Getting microphone input level in IOT Core UWP windows

Question

I am trying to get the actual microphone input volume while recording.

My task is to start recording when the sound rises a little. I found NAudio nuget, but it seems that the wavein class does not exist in UWP. How can I get the actual microphone input volume in a C # record without recording?

Answer 1

I was looking for the same thing. Have you found anything?

If not, you can check this link

Windows Kernel IoT: Audio Levels https://blog.falafel.com/windows-iot-core-sensing-sound/

It uses the following components 1) Electret microphone amplifier - MAX9814 with automatic gain control 2) MCP3008 - 8-channel 10-bit ADC with SPI interface 3) Unknown artist-Plus 4) Your existing installation of Raspberry Pi core - Windows IoT Core

If the above does not work, try this Youtube URL and it may give you some hint to find the actual code: https://www.youtube.com/watch?v=f3Wt4xpkBYk

I tried and tested the code as it is in my project, and it worked. Although there is a hardware dependency, for example, you may need amplifiers to make it accurate, otherwise small sounds do not work. But then the amplifiers should be handled well, otherwise the smallest sounds can greatly affect the bar. I am trying to change this to work with any USB microphone or computer, so I do not need to rely on the equipment mentioned.
