Okay, A little information first. I'm a complete rookie who's in WAY
over his head on a project. Take pity on me, and throw a little knowledge and love my way ![]() First, the rig. Laptop is a Toshiba 2.8gig processor, 512mb ram, 60 gig HD. Audio interface is Echo Layla 24/96, with a Beyringer ADA8000 mike pre-amp ADATed to it. I record with Cool Edit Pro. I mainly use this rig for archiving a band here in Austin (The Gourds). I wanted to switch from doing straight sbd patches to doing matrix recordings with multiple mikes. I mainly only run 4-6 channels, and its performed like a champ since I got the unit in the spring. A friend here in town does video work, and was shooting a dvd for another local band (Vallejo). He asked me to come down and cut the audio at the show he was filming, and the band wanted to multitrack it so they could do some post production work on it. We did some sub mixes to get it down to 14 channels, I set up a set of room mikes, and we let it rip. About twenty minutes into the show, I noticed my display was acting a little flaky, but I figured that it was just having a hard time displaying all the seperate tracks, and besides, couldn't really stop the show. System ran fine otherwise. After the fact, several problems arose: 1) All the tracks show a running time that ends EXACTLY on .000. They are all the same length, except for the mike tracks, which are exactly 10 seconds longer. 2) The "tech guy" in the band, who was doing the post production work, says that the sample rates are off. He had to alter the sample rate to 448000k from the original 44100k. 3) The BIG problem: at about the 20 minute mark, the tracks begin to get out of synch. Some are in synch for the entire session, while others are not. Basically, I have two questions. What can I change/modify on my machine to make sure this never happens again, and; are we totally screwed on the project? I'm sort off learning as I go with digital audio and DAW's. So any advice would be helpful. Also, if throwing money at this project will save it, money can be thrown, within reason. Thanks in advance, and if anybody's ever in Austin, I'll pay you back in food, wine, shows, girls, whatever you want. Michael Barnes |

m... 1) All the tracks show a running time that ends EXACTLY on .000. They are all the same length, except for the mike tracks, which are exactly 10 seconds longer. They *should* all be exactly the same length, shouldn't they? Weren't they all recorded together? The fact that they all end at .000 could just be a coincidence. I just can't figure out why your room mic tracks would be longer though. That's weird. 2) The "tech guy" in the band, who was doing the post production work, says that the sample rates are off. He had to alter the sample rate to 448000k from the original 44100k. Huh? *Why* did he have to change them? What did he say was wrong with them the way they were? And *how* did he change them? 3) The BIG problem: at about the 20 minute mark, the tracks begin to get out of synch. Some are in synch for the entire session, while others are not. How are you playing this back? That's just about the screwiest thing I've ever heard of, so I'd check to make sure there isn't some deficiency in the playback system before going any further. Are you sure someone isn't overlooking something, like maybe editing out a couple little snippets here and there on certain tracks? Something that would result in the rest of that track sliding back a bit? Or maybe altering sample rates differently on some tracks compared to others? If that's *not* the case, can you identify the input source of the "bad" (i.e. "out of sync") tracks? Is it a case of the tracks that came in via the Layla directly are okay, while the ones that came in through the Behringer are off (or vice versa)? If so, you might have a clocking issue that needs to be resolved (identifying one converter box as master and slaving the second A-D converter box to that clock). -- "It CAN'T be too loud... some of the red lights aren't even on yet!" - Lorin David Schultz in the control room making even bad news sound good (Remove spamblock to reply) |
