Hello John, I normally use different measurement software but I am trying to develop some procedures in REW. I am using an XLR mic + RME Fireface UC to do all my measurements. The mic is on a proper mic tripod, and I moved all the furniture out of the way between mic and speaker. The mic was at...

That is a good point. In any case I will be making new filters this weekend. I have lost faith in the old ones - they sound weird and measure weird.

Yes 3ll3d00d, I thought that the difference was quite odd too. But I started this thread on this forum to figure out how to take the measurement because I could hear a difference between HQP and AC. The result recorded by REW confirms that there is indeed a difference. I posted a discussion...

Thanks John. I was watching the meters like a hawk and I did not see any clipping. There was about 15dB of headroom. My reasoning is that high level volume improves the signal to noise ratio? If my results are invalid i'll have to repeat them. What do you think?

I managed to figure it out. For the benefit of anyone else wanting to perform the same procedure, here are all the steps required. 1. Create log sweep for offline playback - In REW, go to "Generator". You will get this screen: - In the Generator, set start frequency 20Hz, End frequency 21kHz...

Thanks John. I'll go and take another look. This is giving me a headache.

I don't think I did. In any case, if I select "Use acoustic timing reference", REW shouldn't output a sweep ... should it?

All right, I have run into a new problem. REW doesn't wait for the timing chirp, it just starts measuring straight away. I am using the newest version of REW which I downloaded yesterday. I followed the procedure in...

I followed the link in your signature to this article when you replied to me thread :) Thank you for posting, it is very interesting. I have a question though - HOW does EQ actually reduce bass ringing? Is it a function of how much energy is put into the room? If so, would you expect more...

Thank you so much for your help gents, especially 3ll3d00d - are you Matt Khan? I'll take a look at this when I get back home later. Most grateful. Let me see if I have the procedure correct. 1. Use REW to generate .WAV files of logsweeps 2. In my playback software, this is what I set: -...

Hello guys, and thanks for the great software. I have been using it for years. Please excuse my ignorance. I do not have a background in pro audio. I am a consumer audio hobbyist. I bought a RME Fireface UC to help implement my 8 channel home stereo. Background of my problem: I am running a...
