Title: Clicks in ripped to FLAC tracks
Post by: shieber on March 12, 2015, 09:42:08 am
I don't think this is a Pono issue so I thought it would be okay to throw this out to the larger group for suggestions anyway.

I've ripped CDs to FLAC using default settings in PMW 20.0.72 (Pono version). During Ponoplayer playback, with many clasical recordings I am getting small, sharp clicks in the background, sometimes even in the simpler passages with only a few instruments. The clicks seems to occur in the exact same place with each playing of a track so it it is likely something in the flac track.

Likely suspects: need slower ripping speed? (rip setting is curreently at default, i.e., max); Bad Drive (alas seems all optis are pretty poor quality these days)? Some buffer or latency setting? All the woodwind players in the world badly need to replace their keypads?

This is happening using four diff optis so I don't think it's siply a bad drive problem.

Not sure what pmw is as a ripping program?

The easy thing to try is to rip to a .wav, see if the clicks are there.  Or even high bitrate MP3.  Just as a test

There are other things to try but again, did you mean MC20 not PMW 20?

PMW is the custom MC version for Pono.

Are you using secure ripping? That should prevent errors, no matter the rip speed.

I've had problems even with Secure Rip.  It gives up after a certain number of retries (16?) so you can still get clicks.  I recently ripped my entire CD collection (600+) and I've already noticed a few that need to be re-ripped because of clicks and dropouts.

If the rip goes really slow (x1 or less) then you need to clean the CD and retry it.

I'll check if Secure Rip is set. I had looked for an Error Correction setting but didn't knwo that is what it's called.  Thanks, hope that's it.

This, unless the disc has label-side damage. Here's a helpful site: http://wiki.slimdevices.com/index.php/Repairing_damaged_CDs

Thanks, but it's not a CD is a bunch of classical CDs, which is why I suspect it is not, or not entirely, the disks. Their appearance is visually pristine even with 10x mag.

Secure mode is the default setting, although we had a recent bug fix where systems with multiple disc drives would have one drive fall out of secure mode.  Double check that it's set to secure mode and then rip one of the problematic CD's.  Let us know your results, thanks.

Indeed, secure mode was turned off. I don't know why. Quite possibly I had turned it off at some point when I was just poking around. Or maybe it reset when I updated with the beta, which is not the standard update method for the Pono fork. Anyhow, All the optis are set to secure now. I won't have a chance until this weekend to see if it solves the issue for me.  Even if I have some slightly wonky disks, ripped too fast, or have a slightly wonky drive, secure mode will probably correct for a lot of that, whatever that is.

Thaks all for taking the time to respond.

Interestingly, If I set an opti drive to Secure mode and rip it then close a drive after ripping, and then I use action window to open Ripping again, PMW resets the drive method to Nrmal Mode. So I have to check the mode before each rip. Is there a way to set it so it sticks?

The fix I mentioned hasn't made it into the Pono build.  There should be a new build this week.

Aha. Thanks for letting me know. I'll keep an eye out.
