Default Creating impulse responses for eq etc

So, I tried making an Impulse response of an eq type setting. Created a test tone, used the plugin in on it, recorded the output and deconvolved it.

The problem is the resulting IR behaves like a reverb, an you can hear the sweep. How would you go about making a short EQ type IR. Just use a very short test tone sweep?

i attached some 1 sample duration pulses (impulses).
there's one for each (common) sample rate up to 192kHz.
they are @ 0 dBFS so you may need to adjust the level.
they are "centered" at 1 second in a 2 second duration file, but you may want to adjust the placement and/or length of file depending on how long the IR needs to be.

edit: there is no need to do any deconvolution or anything with these, once the impulse is run through an EQ it is the IR.

This type of setup introduces unnecessary numerical errors, even when deconvolved properly.

Just turn the EQ ON and feed a one sample duration pulse with max volume into it. Record the output to the point where the output drops to zero and that's your impulse.
