    Use REW to analyze recorded acoustic noise ?

    Re DanDan's comment:"Sure, why not?" Well, Audacity has an input gain control and who knows what Windows might be doing. So I did a test: ran pink noise in my listening room, got a REW RTA measurement with the mic plugged into the computer running REW. Then I made a recording from the mic...

    Use REW to analyze recorded acoustic noise ?

    Thank's John! I was wondering whether Audacity would record the UMIK mic bits without alteration and whether REW could work with files. I very much appreciate the quick answer.

    Use REW to analyze recorded acoustic noise ?

    I'm going to get my car treated to reduce road noise in the cabin. I want to do before/after measurements. I'd like to use the REW RTA for that. I don't want to try and do that while also driving (duh) so I'd like to record the noise using the UMIK calibrated mike and then be able to play that...

    Absolute level cal with REW generator and SLM

    A bit more info and another question for John. Anthem let me know that ARC reference level is at Volume setting of -10 dB. So if that's 85 dBc SPL for -20 dBFS pink noise it explains what I'm seeing; I've been targeting 85 dBc at Volume setting of 0 dB. ARC is apparently calibrating so that...

    Absolute level cal with REW generator and SLM

    I'm having a tough time level calibrating my new Anthem AVR MRX 1140. I've run ARC Genesis, and I've used the internal noise generator and I've measured level with the REW sound level meter (SLM) with (batch) calibrated UMIK-1 mic, and with Radio Shack SLM. I think the Anthem is setting things...
