    I have the tools available to me to create a test CD to test audio frequencies in your sound system....

    I can create just about any sound ranges you could want....

    I need this for myself, but figure I could make it available to everyone, if interested.

    What I would like in return is ideas on how to make it to suite these purposes best....

    I'm thinking of creating a decent number of test ranges, like 50-150hz, 150-300hz, etc.

    This way, you could reference the track number to see what frequencies are too loud, too soft, or non-existant....


    Any ideas? Any advice?


    thanks!

    Get a good quality prosound 31 band eq, and match those frequencies.

    Then make a swept frequency from like 15hz to 20khz.

    yeah, thats the plan. Except I want to divide the frequencies up into different tracks, so you can pinpoint and focus on specific areas, to solve problems....

    What i'm curious about, is if you guys have any thoughts on exactly where to start/stop each sweep, to really make it helpful....

    For example, I want to be able to say - I think my eq is bumping x frequency way to loud... Let me play track 3 to see if it's real, or just my imagination...

    That's what I meant by matching the frequencies.

    Make 31 sample tones.

    And you want to do a slow swept tone so you can follow it.

    At least a minute long.

    I can't take credit for the idea. It comes like that with some sound meters.
