( Like being able to see where the slider knob is relative to the top or bottom of its range as well as being able to move the knob to control the volume). You should be able to tell what state or level each control is in as well as the ability to set the state or level of the control. Each mixer will probably have at least a volume and a mute control. One mixer will control output (one of the available speakers) and the other will control an input device (maybe the on-board microphone or a sound card line-in). Our app will have two mixers, each with two controls (Mute and Volume).

How to add applications to volume mixer windows#

There are mixers available for every enabled audio device that Windows can find. The Mixer Class is like the machine, the Control Classes are like the physical buttons and sliders and the electronics under them. It has rows of buttons, VU Meters, and sliders that each control a given device. Think of it this way - You have this machine in front of you.

I do not think that mixer code is mine but I don't remember where I got it from but thanks to whoever actually wrote it.Д®ach Mixer class has one or more Control classes. Each app gets its own mixer which in turn feeds the master mixer which controls the device.Д«efore I actually begin, I have to admit that though the GUI code is mine and was recently written in C#, the Mixer code is something I wrote decades ago for an old audio player that I wrote in VB6.

Unfortunately, each app is only controlling the level that goes to the master mixer which, in turn, only fades or amplifies your sound and separately controls the sound from the other app. So in this scenario, it is much like having two studios that share one master mixer which actually controls all the devices but has several parallel inputs and outputs. Our mixer will not be interested in that microphone. Another app may be taking notes by speaking into the on-board microphone while quietly playing them back through the same speaker (headphones). So, our app may be using the line-in source from a sound card and the on-board speakers (headphones). This is because there may be other apps that are controlling levels to and from other available devices, some of which may be shared devices (like speakers).

That is done by a master (system mixer), we only control the levels to and from that Master Mixer. Our mixers do not directly control a device. I am trying to explain something that may seem a little strange at first. One of our mixers will have one slider control and one button control (volume and mute). It would also have a knob or slider to control the volume or level from, for each device. A very simple Mixer will a button for enabling each input or output device. There may also be output devices (Speakers, and Amplifiers) that need to be controlled as well. They do nothing until they are connected to an electronic device that can route that signal onto a recording media (Computer, Tape, Vinyl or whatever). In my imaginary recording studio, there are input devices like microphones and guitar pickups. Actually, using the Windows Mixer is more like needing a suppository. Also, I would like to say that understanding what a mixer is is almost straightforward. I have never been in a real recording studio but I think I know what it would be like. I am a techie and do not sing or play an instrument (over the years, I have earned a comfortable living NOT singing or playing an instrument). mp3 (you can see the documentation to understand those functions).ДЇigure 1: The Desktop with the app and Windows monitoring devices for the speaker and the microphone levels. The other tutorials will talk about recording and playing audio '.wav' files. This first part is about understanding, opening, and controlling Windows Mixers. This tutorial is going to be a three-part introduction to playing and recording audio files using winmm.dll (a WinAPI).
