Hello,

In your project make a reference to the attached DLL file and then add a trackbar to your form and use the following code:

Code: Select all

Imports WaveLib.AudioMixer

Place this below "Public Class Form"

Code: Select all

  Dim mMixers As New Mixers

Place this code inside the "Form_Load" event:

Code: Select all

   mMixers.Recording.Lines.GetMixerFirstLineByComponentType(MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Selected = True
        TrackBar1.Minimum = 0
        TrackBar1.Maximum = 100
        TrackBar1.Value = 20

Place this in the "TrackBar_Scroll" event:

Code: Select all

           mMixers.Recording.Lines.GetMixerFirstLineByComponentType(MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Volume = TrackBar1.Value

I dont know if it works properly because I dont have a microphone at the moment to test it. If it doesnt please wait for someone else to respond.

Download DLL:

WaveLibMixer.zip
