Finally TWO USB mikes, live tryout tonight:


Dr. Ellwood

Recommended Posts

Ok yet another experiment with using the USB mike live into the laptop.. I bought another Sampson USB mike. So now we have two of them and I tried them out tonight at the gig. This time I had the laptop and the mikes where spread out as far as the cables let me with them about 30 feet out from the stage pointed pretty much at the center. Take a listen and see if you hear any stereo image at all? This is a Philly soul tune by the Intruders, called Cowboys to Girls, hope you like it.

Seems to me that I get drums and vocals in the left speaker and bass and guitar in the right speaker.

 

Left speaker dominated in volume with an evea balance setting.

 

Like HT said, not bad for USB! :)

 

I don't know how you are budget wise, but those Mac minis really interest me. About $400 or $500 and Macs are known for their audio and video properties.

 

The mini is smaller than a box of tissues and you could get a little 15" lcd for it.

 

Just a thought..

Ok thanks David,yep I think Zan has one of those! I might take a look at them. I think the song made it through the .wav to .mp3 conversion except I think I hear less bass now on it. One thing about listening to the playback I noticed the sound guy pulled up the background vocals during the song about half way through and I wasn't aware in stage that he did that LOL! Oh and for those of us that where wondering if the Cool Edit Pro would see the other USB mike?...it DOES! I select the other channel and it showes up as USB 2! so that settled that one.

Where did you place the mics?

Thanks I think it's better than with just the one mike? Ok the mikes where on a long table that was about 8 or 9 feet long so I set the laptop in the middle and just put each mike at the extreme ends of the table,laptop in the middle, I guess it was around 30 feet from the stage. There are flown speaker cabinets kinda above the table but I don't know if they where a factor? as far as I can tell what you hear is comming from the mains off the sides of the stage.

Have you tired setting up a "Y" configuration? Putting the mics, side by side and pointing each one out at an angle?

 

You've got a really good stereo separation, much better sounding then with one mic, but the vocals and drums on the left side make the left, very heavy.

 

Different placement might work, also, you could try putting the left track (Drums and vocals) in the center of the mix.

 

I can't offer better mixing advice right now because I can't turn it up too loud. (Sleeping toddler.) But I'm sure that you could get a very impressive, live sound, with your set up.

No haven't tried the Y and you guys told about it but it never fails I get rushed every time, then I worry about the laptop being out there away from me. The soundguy said he would stay and watch it next time but he wanted to go to the casino once we where set up. Yeah I haven't tried to imporve anything using the mixing options in Cool Edit Pro yet,might be fun to mess around with it. When you can turn it up a bit later please do give me some mixing ideas and I can try that. Yes I do hear some separation and I wasn't sure if I would, what about distortion on the recording? we play really loud all the time but it is a big place.

i like your sound though, your a great singer in my opinion.

Thanks, that's the drummer singing. Well this was the first time I actually tried two separate channels because I only just bought another USB mike, yes each mike had it's own channel.

Sounds great, do hear seperation.. and as for distortion factor. it's almost not noticable but as noted the left is more dominate. think if you try the Y config with mics. you should be rock steady. Possibly, if enough time during sound check, see the levels between right and left? and yes the background vocals do come up nicely... good job on your sound guy =)

Hmm now if you hook up a cam in the middle of the two mics ;) we can see the performace as well =) GReat SOUND!

LOL thanks STAMP! I don't know why the channel is louder? in the software I know I set them exactly the same..at least by the number I did? Maybe just that 9 feet of separation made a difference? WOW! VIDEO! gezzz I get nervous enough about the laptop being out there.. but that would be fun to try, I wonder if I could sinc. the sound off the laptop with the video camera? or would I have to just use the little mike in the camera? or does the camera go through the computer too somehow?

You can record the video separately and then add them together later. It helps if you do something to sync them up. I find clapping a few times, once you've clicked record on both devices, works perfectly. This way, the camera can move around and you don't have to worry about the sound changing as the camera moves.

Thanks Craig..ok so you put a marker in the audio like a hand clap, then later you run the sound into the computer while you are running the video playback and add that sound track to the video on it's own channel and then mix down all of it at once..is the kinda right..and could I use Cool edit Pro to do that? I mean could one of my sound tracks actally be a video track?? OR is there a special software to do that?

not sure how many usb ports you have on the laptop.. but you can pick up a 4port usb hub for less then $20 that would expan one of your usb ports to give you three extra (considering if they are all used) if not then you have 4 extra ports to plug in =). and you wouldn't have to use teh mic off the camer unless you wanted to use it as a centre channel. then it would make it much easier for syncing the music to video if it's off as well =)

Thanks, well yes sometimes when we are all set up he will run over to the slot machines for an hour or so. It really doesn't happen very ofter and we don't need him riding the sliders all the time anyway, he's got his cell phone with him if we need him to come back fast anyway so it's not really a problem and this room was dialed in along time ago LOL!... He can run the lights from a console by him or we have a chase selector on stage too, so if I hit some preprogrammed auto chases we are fine. On the recording stuff, I'm not sure how many channels will record with the Cool Edit Pro? I've just used two so far with the mikes. I don't know if I would run into latency with more..I guess that depends on the computer?? So you are saying try to get a channel into the computer from the board and also use the mikes and then mix them all together?

Stamp, this laptop has three USB ports and the other laptop has three. Oh and if I was to try to get a feed off the console I couldn't use USB I would have to get some kind of interface along with the USB ports .....right?

OH, ok I see what you mean. In this case on that track the mikes where 30 feet away so if I added a feed from the board and left the mikes pretty much where they where I would get the room acoustic with the sound from the mains AND get the room ambience from the USB mikes. Could there be a phase problem doing that? or would there be a delay of any kind that would be a problem do you think? if I tried that would 30 feet out from the stage be too far do you think?

Hey! If it wasn't for that other thread I'd have totally missed this as I don't often post on the weekends. Where's the love, Lee?? :D

 

Anyway, I scanned the thread as I listened to the track. I'm really confused.

 

One side, as mentioned by others appears to be all drums and vocals and the other a muffled track of everything with little vocal. There is no bass whatsoever in the drum/vocal side, which may explain the near absence of bass and guitar. Can you draw a diagram of the mics in reference to the band, FOH and monitor speakers?

 

A couple of comments on the C01u. As we previously discussed, you can plug in as many C01u's as you have USB jacks on your PC and each will come up as a separate input. You could, theoretically, take a feed from the board and run it into the 1/8" analog line-input jack on your laptop and use it simultaneously, depending on the capability of your recording program.

 

Just remember, multiple C01u's are not possible with any Mac, according to Samson. Do not expect to buy two of these mics and use them together into a Mac.

 

As for the Blue Snowball and the new product on the market, Rode's Podcaster I can't say whether they can be used in multiples with Macs, but it would be worth looking into for Mac users looking for usb mics that can be used simultaneously.

HI Neil! LOL I though you saw it and where ignoring it! because it offended your professional sensibilities LOL!!!! ok, I can draw a diagram... BUT I DON'T KNOW HOW TO PUT IT ON HERE..unless I take a picture of it..would that work ok? I know there are ways to do graphics but I don't know how to do it!! the only thing I don't know is why you can't hear guitar, I can hear it in there quite abit??

Well, it's there but very low. Mostly I'm confused why the bass frequencies are lacking in that channel and why the vocal is almost entirely in that channel and not much in the other.

 

As for a diagram, you can use most any graphics program to quickly draw lines and shapes. I like to use photo manipulation programs for that. Either Photoshop Elements, The Gimp (free) or Snagit's Snagit Editor or Snagit Studio.

I don't know either Neil? Ok I'm going to try to draw someting with one of those programs. I think I got better results just using one mike? I though it would be better! anyways maybe moving them around or someting will help it, I'm going to try to do another one tomorrow night or Saturday night and see if I can improve it.

Usually, if the issue is phasing between mics, it goes away when you're listening to one or the other mic.

 

Phasing is the interaction of sound waves hitting each mic at a different point in the wave front. If the sound pressure is pushing on one capsule at the same time it pulls on the other, the combined signal will be reduced. As various frequencies have different wavelengths the combined output will not simply be lower output, but a nasty, comb-filtering. With only one channel playing there is no interaction and no phasing. ;)
