using REW with a presonus firepod

ok...very very very new too all this.
I have a presonus firepod and a ECM8000 mic. I'm just trying to get a reading for my room. No eqs involved at all. Thing is, I have done all this reading on here and i still can't get anything to work. I'm 99% sure i'm not doing this right because I can't even calibrate the soundcard.

has anyone used a firepod with this software and can they tell me what to do?

thanks!!

Are you using the firepod with a Mac? There are problems on Macs with access for Java programs to the inputs of USB-connected soundcards which may also affect FireWire-connected card inputs - USB got a mention as being fixed in 10.5 but I don't recall any comment about FireWire. If you have a device with a line signal (e.g. an SPL meter) or a preamp for your ECM8000 try connecting it to the Mac's built-in audio input and see if that works, or try going through the soundcard cal using the built-in input and output.

its a pc.
Also, i don't have a preamp for the mic because the firepod is in itself a preamp.
I also don't have an spl meter with a line out Hence why I got the mic in the first place :P

and what is the soundcard cal?

thanks!

I see no reason that it won't work then.

Hopefully you're using XP.

Can you show us the REW settings page.

so, i went behind the unit and put 2 rca's into the line 1 and 2 inputs to the line 1 and 2 outputs (not the master outputs nor the main front inputs).
I got something out of it but it won't save as a cal file. keeps saying its missing something. I'll write down the error next time. Now I have NO idea if it worked at all. Not much is showing up in any of the reports.

Try setting to 48KHz.

REW is seeing the card, but are you able to select a specific input and output (line 1 out for example) instead of Defaults. I know that system has multiple inputs and outputs.

If you are trying to do a soundcard calibration routine, you must have the Use Left Channel as Calibrate Reference unchecked and leave it unchecked. You want to only connect a single line-out to single line-in and run the routine to obtain a cal file. Then that short is removed and you use that same channel for measuring (while the cal file compensates).

thanks! i got the sound card calibrated properly!!
