Things to check first (yes, these are pretty basic):

• Do you have a mic hooked up to your computer?
• Do you have the most recent version of the Flash Player plugin?
• Have you checked 'Allow' for aevidence.com to access your mic? (use the 'Settings' button)

Now perform this test:

• Click on the 'Settings' button
• Click on the third tab along the bottom - 'Microphone'
• Typically you will want 'Built-in Audio' selected from the drop-down
• Check the 'Reduce Echo' button and turn Volume slider up half way
• Make some noise. You should see the level meter on the left responding
• If you see levels, adjust the Volume slider so that the meter peaks just below the red, and try recording again; if not, continue...

If you do not see levels:

• Check to make sure your microphone is turned on per the instructions on the recording page.
• In Windows, you can perform a "Hardware Test" of you audio hardware. This function is located in slightly different places depending on the version you are using, but it is always in the 'Sounds and Audio Devices' Control Panel. Use this to ensure the hardware is functioning properly.
• Make sure your mic isn't broken - test it somewhere else.
• Try detaching any docking station or external monitor if you are using a laptop. Though this sounds strange, these external devices have caused problems in some cases.
• Email me if you are totally stuck.

I don't have a mic on my computer!

• Well, if this is true, we have a problem, but...
• You might have a mic and not realize it. Look for a small hole in your laptop case.
• You can plug a 'real' mic directly into your computer with the proper adapter (XLR --> 1/8" or 1/4" to 1/8")
• A computer/phone headset works well. Just plug it into the mic jack of your soundcard
• Some cell phone headsets work as well (must have 1/8" mini phono jack)
• Radio Shack sells computer mics for around $10

Don't give up. Your voice is very important for this project!
