Software to check the bandwidth of my desk

Hi Guys any one know of any freeware software that I can use to check the bandwidth of my desk, am looking for something that will generate the test signal as well as record it and display a frequency graph.

Ideally for a Mac but Pc is also good.
I did find an interesting site with lots of useful stuff but the only one on there does not seem to work on my pc it crashes as soon as I start it, any way here is the link: PC Based Test Gear

looking forward to some links back

Probably best to purchase a simple sine wave generator - as you will possibly want to look at what happens above 20KHz.

You should be able to use the meters on the mixer to give a fairly accurate indication of the level, but it won't give you a nice graphical presentation as some of the software will.

For serious investigation - the use of a proper audio analyser is the way really, but they are rather expensive, even to hire.

Hi Mixermend
Thanks for your reply I found Tinnitus Sound Therapy Treatment - Tone generator & Tuner | AudioNotch very useful online generator, this is useful for testing the desk for faults but for bandwidth you need something that generates an impulse response and display the results on a graph.
at this stage I would rather not spend any money as you mentioned the generators are expensive, there is some good software out there I just want to know if anyone has used anything I can use for this purpose.
cheers

There are applications like this...

Soundcard Scope

But, of course, they are no better than your computer sound card.

FuzzMeasure Pro 3
Electroacoustics Toolbox

not free but you get pretty much full functioning demos....

Indeed, the frequency response of your sound card (and generator) should go well above 20 kHz and probably below 20 Hz as well. The "proper" method to check frequency response is to sweep a sine wave generator over the range to be tested and measure the levels with a good meter, both items with a frequency response better than 20 Hz to 20 kHz.

Thanks for your suggestions, FuzzMesure pro looks very interesting I should give it a go over the weekend and see how I get on, I will keep you guys posted,in the mean time I would be very interested to hear form any one with diagrams or experience of CAD Maxcon II desk

Thanks Stickyfingers that FuzzMesure is great, I done some testing and I got some interesting results, I will having a closer look at them to see if i can find anything.

The upper limitation is the macbook built in sound card

first up is my monitor out am only testing 1 of 3 for now
Right channel 336ms delay and signal is lower then the left but I new that, the Left channel has a 35ms delay
I know there is a problem with the amplitude but why the delay difference?

Then I checked the Mix inserts
Left channel 336ms delay?
Right Channel 32ms delay?
Left channel the oscillations continue right up to 1Khz
strange
