Hello!
Using LIMP and EMU 0404 for impedance measurement and getting in a LIMP setup stage error:"The specified format is not supported or cannot be translated. Use the capabilities function to determine the supported formats"


What shold I do after doing lot of googling and founding nothing as a solution?

Sounds like you are selecting a sample rate / sample bit depth that your device doesn't support. Also are you choosing WDM or ASIO sound drivers ? ASIO may not work on many cards even if they claim to support ASIO. (My Audigy 2 ZS claims to support ASIO but none of the ARTA tools can access it in ASIO mode so I have to use WDM)

Finally, do you get similar errors in the main ARTA program ?

OK! Sounds this helped - I did increase sampling rate to 96000. I am measuring 3-way speaker:
2xparallel Dayton audio RS225
Seas 15RLY
Peerless 910821

As a hardware i use this jig here:
AudioBlog: A simple loudspeaker measurement jig for ARTA
reference resistor value 15,6 Ohm

and ARTA setup as here:

Starting measurement I get always warning: maybe you need to exchange input channels. So, first question - are everything correct?

WOOFER test
I do have bass reflex system, but measurement curve (impedance) does not look very good. I have tuned it with Unibox to 32 Hz. Where I do have mistake?

MIDRANGE test
Looks good?

TWEETER test
Not bad at all

PS! this is my first ever test with drivers, so I may ask maybe very trivial questions.
