....I recently installed Audacity 1.3.x (Beta) on my new pc with a Windows 7 OS....I tried recording and the first three seconds record fine but after that it sounds like it's going through a flanger of some type....I have all my effects turned off and am sending a dry signal...also, when I go to choose an input on the mixer bar I can't there's only four choices, not like audacity 1.2.6 where there was a choice of CD, microphone, stereo, mono, etc....what am I doing wrong?

Check that you do not have "software playthrough" selected (Transport menu).

Was that also on the same computer with Windows 7?

That is terrific :D
It's the most dramatic demonstration of "Noise Cancellation" that I've ever seen.

Somewhere in your sound card settings there should be a switch or selection box that allows you switch on/off the noise cancellation. It may be called something different (echo cancellation? noise reduction? ...) so you'll have to have a good look through and switch off all effects so that you can get a "straight" recording.

What is happening is that because Your sound card/Windows sees a constant drone (from the didj) it assumes that it is background noise and is doing a really good job of cutting it out. You have no doubt noticed that when there is a sudden change to the drone (when you take a breath), the sound comes back briefly before it is again cancelled out.

soI tried to adjust the device settings, updating the drivers, rolling back the drivers and I still can't record how I want to.....there's no button to click on that says "noise reduction, cancellation or anything like that....so what do I do?

If there is no setting for it then you've got a problem. I've seen laptops where there is no setting for it in the actual sound cards interface (from the icon near the time/date) but there has been one hidden away in the Control Panel. Hopefully it is similar on your computer and you will discover it lurking in a dark corner.

By the way, what sort of sound card do you have.
