Well, it's not a doctoral thesis. We'll see what I come up with. I'm not recording live music, and I definitely will not be using six microphones and doing a lot of mixing. it's the music from two speakers in a room recorded at the listening position. The ideal way to do it would be with binaural microphones and head, but I don't know that I want to get that deeply into it. It's more of just a "fun project".

As I will be needing to buy two mics, and keep this affordable, what mikes would you recommend? I really don't want to spend 6 bills on mics for a fun project.

Setup will likely be a coincident pair as a starting point.

I can't find the clip from the Blues Brothers where he says he sold the original blues mobile for a microphone. Just pretend I included it in my post.

I have a soft spot for my CJ gear as well but don't think I would try and record it. You should just invite us round. We internationals would miss out but I am sure the local guys would partake.

You could try measuring it however, that could be interesting. If you have a sound that you think should be bottled then it would be interesting to see how that might compare to the sound of other peoples systems.

Stephen, what's the listening room like? Size, shape, drywall, paneling, proportions, furnishings, etc.? That and mike selection obviously impose a signature on what you hear, so that if you provide that info along with listening samples we'd have a referential context.

Sounds like an interesting project in any event.

Okay, guys, here are some links to a recording I made on Saturday. I used two CAD stereo mikes with omni capsules in a 110 deg. ORTF setup and an M-Audio MobilePre USB audio interface. Recording is at 16/44k as that's all the MobilePre supports. Please bear in mind that this was the very first recording I made, and I am still playing around with a lot of variables and am learning as I go; don't really know what I am doing. There's clearly some "echo-y" room ambience going on, but it gives you a flavor, if nothing else.

This is the first cut on the new Analogue Productions' 45 rpm LP reissue of "We Get Requests" by the Oscar Peterson Trio put out at the new Quality Record Pressings plant. To play these, you should right-click on the link and download the entire file to your computer. I've noticed that playback seems to sound better in Audacity than ITunes...not sure why.

Both files are approx 28 meg downloads.

Ah, a delicious Corcovado, Stephen. As you indicate, a tad echoey, but for someone who says he "doesn't know what he's doing", a nice job nonetheless. Reminds me of Oscar and company playing a date at the "old" Yoshi's around 1989.

How far are the mikes from the speakers? That might explain the echo.

Thanks, Jim. I would have loved to have heard Oscar and company at the old "Yoshi's" as I lived nearby in Berkeley at the time.

The mikes are about 3.5 feet from the speakers. My understanding from a friend was that for ORTF you place the mikes at half the distance that the speakers are apart. My S3.4s are 7 ft apart, so I put the mikes at 3.5 ft from each speaker. I could also try the wind sock, that might act like a speaker grille and take a little of the highs; the box for the CAD mikes said they are designed to pick up the highs from cymbals and brass for a "lively" presentation, so they are slightly tipped up between 7 and 16 Kz (see omni FR plot pic attached).

I could try the cardioid capsules, that's a bit more directional, might give less pickup reflected from the back walls (see cardioid polar response pic attached).

They're inexpensive CAD equitek e70 mikes, only $99/ea. We're not talkin' Schoeps or Bruer&Kjael here....
