    I was hoping someone could suggest a good CD, DVD, or DVD-A that I could use for a science project my daughter is putting together. We are looking for a disc that would have test tones im steps (ie 80hz, 70hz, 60hz, ect down to at least 20hz or lower). I have some but they are all sweeps and we were looking for some software with steps.

    Any suggestions would be greatly appreciated. We were hoping to knock this out over Christmas vacation.

    Thanks John-

    I have AVIA and I did not see the steps in the subwoofer test area. I guess it is time to check it again.

    I was going to get digital video essentials instead of the original VE. Does this have subwoofer tests?

    Thanks to all-

    I now have a few but I can always use a few more.

    That stryke CD sounds great. While at Tower Records I found Digital Video Essentials on sale for $19.95 and a Chesky DVD-A test DVD for $15.95.

    If anyone finds any others, please let me know

    NCH tone generator might be what you are looking for. The program can be set to output to a wave file if you wish to burn the tones to a CD or DVD. Very useful. But... since I can't post links yet, you will need to type it in manually. Sorry! www[dot]nch[dot]com[dot]au/tonegen

    Here is the link: NCH Test Tone Generator

    Note: be careful. Several minutes at 20/30/40 hz will take a lot of power and can over-heat your subwoofer/receiver. If you burn tracks do something like this:

    Track 1: 20 hz for 5 seconds
    Track 2: 800 hz for 20 seconds
    Track 3: 30 hz for 5 seconds
    Track 4: 800 hz for 20 seconds

    This gives the equipment some time to cool.
