I have been playing with REW and also some other room correction software like Dirac (test version).
However I never was really happy with the results so I stopped using oder buying something in that direction.
No I have heard that active speaker often have digital amps and they would produce some time delay which is exactly what >I observed trying to run my active speakers as "front" within a 5.1-System where the rest of the channels would be provided by a regula AVR.
I have a time delay of about 80 ms in my rememberance, but I am not exactly sure. (Will have to re-do the measurement).
NOW my question: Will a delay between the sweeping source and the output from the speaker influence my measurement results???
Running REW involves these frequency-sweeps. As I understand REW, the mic picks up the signal and provides data in form of a time-Intensity diagramm which is then fouriertransformed in a frequency-Intensity diagramm.
If there is a delay, the Mic may "think" it is measuring a 400 Hz-Signal, meanwhile it is still the 390Hz-Signal, which just comes along a little later....
Thanks for hints on this topic in advance.
System: ADAM Tensor full active Speakers, audiolab pre-amp and CD-player, also USB-Input (which would benefit from some room correction done in the computer).
