Digital Clicks and Pops

Post by Rick Cornish »

I recently upgraded to El Cap and DP 9.1. As I listened back to some recent tracks, I heard quite a few clicks and pops that weren't there in 9.01/Yosemite.

Anyone else find this?

I was playing around with buffer settings the other day and found that if I set the buffer too HIGH, I was getting clicks and pops. That's never happened before. Weird huh? Anyway, have you tried different buffer settings?

Good thought. I usually don't mess with those much. I will look into that today. Thanks, Phil.

You were right, Phil… kinda.

On a full soundtrack mix with 720p video running, a buffer setting of 128k yields clicks and pops. 64k is pure grunge. Dialing back to 256k (which is what I always ran before v9.1) plays back clean.

Do you have any post-fader effects being used? There is a bug in 9.1 that can cause noises with post-fader effects as well.

Nope. All inserts are pre-fader.

Same here after installing DP 9.1. Repairing permissions fixed it. Lots of MOTU and audio system file permissions "repaired." Duh!

Thanks for the idea. I repaired permissions before installing El Cap. Will try doing it again and zapping the P-RAM for good measure.

Instructions on the link. Not as elegant as Disk Utility nor as easy to see what's going on, but it does the job.

I made a clipping of the command line and keep it on my desktop, so when I need to repair permissions I just open the text clipping, copy, and paste into the command line section of Terminal.

I didn't repair permissions after installing 9.1 but I did after reading your post, and found the same as you, lots of permissions related to the install repaired. I don't know if it was necessary (and some argue that it's not), but to the best of my knowledge it won't do any damage and it provides some peace of mind that everything's tidy.

There's not much you can say to defend ignorance. If those folks are convinced repairing permissions won't help, let 'em continue to try and figure out how to solve pops and licks and other anomalies another way. Or they can take two minutes and fix 90% of their problems.

As the piercing place in the Village (NYC) used to say on it's banner: "Pain or no pain. Your choice"

But wasn't it Dave Roberts Himself who said that repairing permissions was usually not doing any good? If anyone feels they can call him "ignorant" on the subject of DP, let him step forward.

In a digital system, pops and clicks come from the computer trying to correct a large error in the data stream. Those errors happens because the clock is mismatched, or the computer has bad drives or is being bogged down by background processes or something. I've never experienced another cause.

But I wouldn't know if fixing permissions does any good or not: I run Maintain's Cocktail for Mac weekly, and my pilot script includes repairing permissions on the start-up drive. Maybe that's why I never have a problem with DP. Based on Magic Dave's words, I have to still doubt it.
