I'm getting lousy THD results. Has anyone used REW to test receiver THD? If so, how?

After some fun getting started with my laptop and REW my UMIK arrived today. Here's how it compared to my GarageBand mic - what do you think? Also I have a bulge @ 50hz and a nasty suck-out/ interference at 128hz - any ideas? Harmon 3770 Wharfedale 10.1 B&W602 sub with X-over at 40hz. G

At this stage of the game, it's overwhelmingly obvious that Netflix has morphed from a young fighter with potential into a dominant heavyweight champ. Earlier this month, the company announced it has surpassed premium content provider HBO in the realm of subscriber revenue. According to...

Anyone know of any software/disks which can test individual speakers? REW sends out only mono signal. It's a pain having to disconnnect/reconnect speaker wires in order to test them individually.

We are pleased to announce a price reduction in our XBL and RevSurround (patented), cast aluminum basket, thermo-formed strand-oriented polypropylene cone VWR126X. This is possible because of ordering larger quantities, amortizing development cost and lowering dealer margins and allows us to...

I have a multi-purpose computer without a Ethernet drop at its location and I've been on a quest to increase its network speed. I'll eventually run cable, but there is no way I'm working up in the crawl space during the summer in AZ. :sn: Short of running copper, I've tried a number of things...

I was just about to do this so that I could put it on my ipod so that I could RTA test some secondary systems (ie car and 2nd TV) but then was like....wait a minute LOL. Since I know some quality is lost, would some freq maybe be attenuated? I know a pink PN is flat all the way across, would...

Hi, Well I've reached the point where a new AVR is just around the corner. I started visiting this site again to get info on the newer models. With a tight budget the "refurbished" or B-stock has become quite appealing to me. What I am most cautious about is how could I perform simple at...

Hi I've been making some measurements today and I noticed how much of a difference my own position in the room makes to the FR graph results. And this has got me to thinking where the best position for my body is when running sweeps...... Is lying down a good idea? I also tried running an...

Hi guys, I have just ran some THD distortion test on my dual FI Q18's and this is on my middle tune which is 17.5hz. I did it to these instructions: Use the RTA Function, set Mode to Spectrum, FFT Length to 131072, Averages to 4, Window to Hann. Use the onboard tone generator in REW, fire up...

Hi All A bit of background. I am a part time muso and electronics guy who spends most of his spare time working on stuff for the band, home recording, building amps etc and chanced on this site whilst looking for some software like REW! I have a 2.1 system that gets used occasionally when...

Hey everyone. I have an xbox 360 and am interested in ways I can use it to play video from another machine. I saw a post here by WBassett that covered the same topic for the PS3 - so I thought I would start one for the 360. I should note that its January 2008 - and I'm noticing a few changes...
