Microphone input

Hi,

I would like to know if it's possible to get the frequency of a sound from the microphone input. If so, I would like to know how, because I'm trying build a guitar tuner.

I would like to do the same thing... here is what I think I know, and what I don't... (i'm doing research, but not getting much help)...

From what I understand you will most likely need to use the FFT algorithm to determine the frequency of the input... however I have not figured out how to get the input from the mic (if you know holler)...

I suppose you could record, and then figure out the frequency, but I can't figure out how to read straight from the input....

Here is a site that should help with the FFT, but any more than that... i'd research general info about playing/storing/reading waveforms.

if you or anyone else can help me put this all together that would be great... I am just having trouble sorting it all out... :)

Hi, im from scotland and as part of my advanced higher studies i have also decided to make a guitar tuner. im wanting it to be able to show a gauge on screen and use that to show how close the instrument pitch is to the desired pitch. I have never used visual basic before, i chose this project as i thought i could manage it but im finding it extremley difficult to find much information on analysing sound in real time. im not even allowed to change my project. thanks very much to anyone who can help
