VS 2008 Getting The Volume And Pitch Of The Sound Currently Entering The Microphone
Sep 12, 2009
get data like the pitch and volume of the sound currently being "heard" through a microphone?
Do you know the little graph which the Windows 98/XP sound recorder used to show? It used to show the pitch and volume of the sound which was being recorded. Like I want to get the data from that.
Basically, I will start experimenting this stuff by showing the volume of the sound entering the microphone in a label. And maybe the pitch too.

I'm pretty new to VB and I chose a project for school to recognise the pitch/note of a sound comming from my microphone (Which I'm using singular notes using my Guitar). I have no idea if this is even possible :/ So if possible, what things should I be considering and what I pretty much need to do to get the ball rolling for me

I'm learning to play the Trumpet and thought it would be a great idea to write myself a flash card type program that would flash a note, pick up the sound from the microphone, determine the pitch, compare it to the note and evaluate right/wrong. For example, it puts a middle C on the screen, listens for a tone above the din and beeps or buzzes if the result is right or wrong.

I am rather new to VB and every now and then I get an idea of a small project I would like to work on to increase my skills. What I am trying to do is:
1. Input the sound from the microphone
2. Detect what pitch the sound is
3. Compare it to the pitch displayed
For example, lets say I was to have the button "Start". When start is clicked, a pre determined (Or possibly random) note is displayed through a Label for 5 seconds (Lets use C as an example). During this time, the user can attempt to match the note C. When the user sings through the microphone VB picks it up, detects what note the user is singing at, and then scores him over the 5 seconds based on the difference between his note and C. It would also be nice if I could display the volume of the microphone, but this is not too important.

how to even get started with this, so I need a few tips. writing code that will allow me (or my program) to "see" what the pitch is of the sound that is currently being detected by my microphone. I am familiar with VB.NET, and Java. I think this is called a spectral analyzer... I want to build a very primitive one.

I am trying to write a countdown timer I finally succeeded with MSDN. I get to work whatever I wanted, but this drives me nuts: How can I read and set the volume control? I want, once my timer is run down to zero, read out the current system setting, then play a system sound using
Media.SystemSounds.Exclamation.Play()
Over time I like to ramp up the volume to 80% or until one clicks the Alarm off button (then stop the timer, no sound, and reset volume).

I am looking into recording sound from a microphone using vb.net into a wav or mp3 file. I've Googled loads but only found 3rd party controls and C# code, which looks too sticky to convert..[url]...
I found this article on the code project which uses WaveIn and WaveOut but this looks unconvertible.... and I would like to avoid using DirectX SDK because the installation files are large and I wouldn't like users to have to do that.

Does anyone know how to get and set the system sound volume? I have tried every method I've found on the net and none of them work. I've tried the winmm.dll APIs with no luck. I've also tried waveOutGetVolume/waveOutSetVolume, which didn't work. I'm using Win 7, but need a solution that works on XP+.
Right now I use the VolumeUp keyboard event, but I need to be able to get the volume and set it to a specific level.

I need to make an application that plays the microphone line in the same time I speak to it, somewhat like an amplifier, so I can talk to the microphone without recording and my speakers play that sound at the same time! Its pretty difficult for me because I am really new at this type of applications and off course I don't have any idea about microphone line in volume control coding too!

I'm entering 123 into a field and getting 231.It's because I'm formating the text as I change it.
Private Sub txtObject_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtObject.TextChanged txtObject.Text = Format(Val(txtObject.Text), Zformat)
End Sub zformat is "0.0"
Initially the field is "0.0". If I highlight it and type "1" I get "1.0" the cursor is now in front of the "1",I then type "2" and get "21.0" and the cursor is in front of the "1",I then type "3" and get "231.0".
It is because the cursor is in the "wrong" position.Is there a simple way to fix this?
