Is there a way to get Visual.net to display the sound coming in the microphone as a graph on the screen? for example it would show the frequency and intensity of the waves.

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
View 1 RepliesI was just thinking if there is any component which monitors sound output. My intention is to recognize a particular sound coming out from my soundcard. I know its an issue about the driver of my sound card but is there a way I can get atleast noise level coming out of my speakers and maybe draw a graph and detect the peak at when the sound is played?

View 4 Repliesget 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.
Problem I'm facing now is when the call is going, there is alot of noise coming out form the speakers. I want to cancel all the other sound which is coming out other than the voice. I want to cancel echo.How can I do that?

I want to make a program that detects the note that is being played in front of the microphone. I am testing the FFT function of Naudio, but with the tests that I did in audacity it seems that FFT does not detect the pitch correctly. I played an C5, but the highest pick was at E7.I changed the first dropdown box in the frequency analysis window to "enchanced autocorrelation" and after that the highest pick was at C5.

If VB.net can do it? Is there any tutorial link you can recommend for me? Video link much better.

View 2 RepliesI've been hired at a company to fix some bugs and make some improvements to their in house programs. The program I am currently working has been written in Visual Studio 2005, in Visual Basic specifically. The program is used to connect to a database on a server and provide various information. However, I have run into a snag where the program will refuse to connect to the database when it using a user account and password that has been set up on the database. When I look at the logs i see it is giving the error as stated above, however, I have double and triple checked the password both on the database and the one hardcoded into the program and they are identical yet it still logs that there is a password mismatch. Has anyone run into this problem or figured out a solution towards fixing it, I will be much obliged.
