Digital clicks in track - solution?

    Hi I have this problem. Up close sometimes it looks like a big square wave or just flattenns the signal entirely. I never lasts more then one wave. Doesn't matter if I'm tracking or just processing through outboard gear. Right now I'm using DP 4.5, motu 828, and Mac g4. I am pretty sure its either a computer problem or a DI problem. I was thinking about upgrading one or both, but would this solve the problem?

    thanks in advance

    Clock issues.

    If they're quick, intermittent clicks, you might have a clocking discrepancy. Are DP and your MOTU inerface both set to the same sample rate? Is the 828 the master clock or is it internal?

    Like they said, clock jitter. Everything should be synced up and following a master clock.

    In Pro Tools you can zoom in to sample level and draw the clicks out with the pencil tool, but if theres tons of them that could get really tedious.

    do you have a dedicated audio only drive?

    Not trying to be offensive at all but for the sake of people trying to learn here I have to say a couple of things.

    First you state...

    First clock jitter is something completely different. Jitter deals with bits and PLL. The "clock" deals with the sampling frequency that a device or mulitiple devices are running. And, the sync begins and ends with the master. If it didn't then there would be no full looped communication between all the devices.

    Secondly, and frankly where it gets really strange

    You're suggesting to this guy to draw out clock issues at the sample level!?!?! Again for the better of the rest of the forum... Do NOT ever do this. ReRecord!!! If you have a clock issue when recording you don't have a take.... do it again!!

    And finally in your sig. it says you are Pro Tools Operator Certified. I'm sorry but from just the few sentences you have typed here there is absolutely positively no way this could be true. A PT Operator would never have uttered any of those comments.

    Thanks for the responses. I am way over my head here,

    Under Audio System Clock The master clock is set on Internal but Macintosh Build-in in is given as another option. I assume this means( :roll: ) the 828 clock is being used as the master clock? (The audio system is set on motu) The sample rates are on both systems are set at 44.1 - 16bit

    You can draw them out most of the time in Dp, but sometimes it seems to get worse or I can find them. At the moment I'm just doing a dialogue project so if this fails I just cut 'em out at the nearest nodes. Sometimes if its my own voice I re-record. Are you suggesting using a stand-alone clock, such as Big Ben, as a solution?

    I Dont have a dedicated drive. I only run DP When doing any audio work. I don't know if that matters or helps.

    thanks again for the responses

    Actually, to avoid arguement, I said it was most likely a clocking issue, I never connected clocking issues and trying to manually draw them out, which wont happen (and wouldnt make sense).

    Then since he mentioned clicks and squared off waveforms I mentioned you can zoom into sample level to draw them out, which I have been taught personally by many MANY renowned engineers, as well as done many times myself (and in reading, the poster has successfully done too). Yeah you can rerecord something, but if your in the mixing stages and the band is long gone, what do you do? You draw it out, its completely inaudible since your most likely drawing a line at zero amplitude, or just taking down the very peak.

    As for questioning my Pro Tools certification, if you want I can PM you my Digidesign ID and you can search me on the certified user database on their website (A side note, Jay Fleming and Todd Rosso were my instructors, 2 of the 7 Experts on the entire planet).

    Sure you have your way of doing things, I have my way, and I've been taught about 6 other ways.

    No need to blow up, it was just a simple idea.

    what speed G4, amount of RAM, how much free disk space?

  10. havent read the whole thing, but drawing clicking out like this is really not a solution -- fix the problem at the source.

    hope everything works out!
