How to make a sound level meter and show the value in …
https://www.codeproject.com/Questions/5255839/How-to-make-a-sound-level-meter-and-show-the-value
Hi, i need to do a kind of vu meter in visual studio. I have to do a program with an interface. I need to mesure the sound recepted by my stock microphone and see if the sound is to low or to loud. I thinck that I have to mesure the decibels and define the decibel limits of low or loud. I need help, I am new programing.
c# - NAudio Peak Volume Meter - Stack Overflow
https://stackoverflow.com/questions/14350790/naudio-peak-volume-meter
All that is happening in that article is that it is finding the maximum audio peak over a small interval (e.g. 20ms) and then plotting that on a decibel scale. To find the peak, examine the value of each sample in the interval and select the max value (It's what the SampleAggregator class is doing). To convert to decibels, take the log base 10 ...
Sound Card Output Audio Processing in C#

1. Convert the sound output (amplitude) from the sound card in to floating point numbers ranging from 0.0f to 1.0f. 2. Additional requirements: a) The audio can be split up in to 4 different frequency ranges: ie one floating point number for the amplitude of frequency range 0kHz to 4KHz for voice. one floating point number for 4Khz to 8KHz.

The two most common options are 16 bit signed integers (short's in C#), which is what WaveIn and WaveInEvent will supply by default. And 32 bit IEEE floating point numbers (float's in C#) which is what WasapiIn or WasapiLoopbackCapture will supply by default. Here's how we might discover the maximum sample value if the incoming audio is 16 bit.
Audio graphs - UWP applications | Microsoft Docs

The audio graph API allows you to add audio effects to every type of node in a graph. Output nodes, input nodes, and submix nodes can each have an unlimited number of audio effects, limited only by the capabilities of the hardware.The following example demonstrates adding the built-in echo effect to a submix node. C#.

https://www.circuitstoday.com/audio-wattmeter-circuit
This is an easy trick to measure the output of an amplifier. Here resistor R2 acts as the load for the amp and it should be able to withstand twice the maximum power of the amp you are going to measure. The meter scale must be calibrated and with a little effort, you can get good results. Audio Watt meter Circuit Diagram with Parts List Audio ...
Understanding And Controlling The Windows Mixer API
https://www.c-sharpcorner.com/article/understanding-and-controlling-the-windows-mixer-api/
This tutorial is going to be a three part introduction to playing and recording audio files using winmm.dll (a WinAPI). This first part is about understanding, opening and controlling windows mixers. The other tutorials will be about recording and playing audio .wav files. We will not be working with .mp3 (you can see the documentation to understand those functions.)
