    Hi! Like the true geek that I am I have just got hold of a sound pressure meter to callibrate my yamaha ax1.
    Only problem is that I have no test signals to help with this.
    I need a set of pink noise mp3's from around 100hz to 16000khz.
    Anybody care to e-mail me some?
    Ta!

    I have a feeling that mp3 encoding would trash a pink noise signal :-O

    If you can connect your PC to your hifi then you could download a signal generator like NCH which has a pink noise generator.

    Thanks for that, I have nowo got a copy of NCH. But what sort of wave form pattern is the best one to use?

    Well, the nature of noise is that it should include the whole frequency spectrum so you'll only be able to test overall output with a noise generator.

    For test tones, the only thing you should send to your amplifier are sine waves (the curvy ones). The others have the potential to do quite a lot of damage to your equipment. :)

    Thanks, I thought it might be sine waves because everything else was far too sharp on my ears!
    My amp has a variable test tone generator which tests each speaker in increments up to 250hz for bass response testing purposes.
    However, I now realise that the nch generator is only 2 channel. So I will have to find some sort of source that will give me sine wave frequency increments that pans around the different channels.
    I wish i had never started this!!

    That would have to be a digital source. Something like Avia Pro (or even vanilla Avia or DVE) might do it, I've no experience of them I'm afraid.
