Just two matrices into my post-pro's on the SFBOT and it hit me like a ton of 148's. My Wavelab is dropping about 150ms of music when it auto-splits at its setting of 1995MB!!
holy crap :o
-
you got proof of that? ive merge things that were split with wavelab and never noticed any gap and id say 150 is noticable for sure.
-
I'd check your setup. I have used WaveLab hundreds of times and have NEVER had dropped samples at an auto split. Adjust your buffers and maybe think about splitting earlier, say around 1500 megs, and see what happens. Definitely sounds like a buffer issue as it is not opening a new file quick enough and dropping those samples.
-
Your problem could also be caused from a fragmented/unhealthy drive. Your WaveLab default buffers should be suffiecient, but depends on your recording preferences, bit-depth/sample rate, audio card, computer setup, etc. Typically, smaller buffers are used in the studio environment for super low latency/monitoring. Larger buffers can be used when latency isn't an issue like in our application. The buffer is basically the size of the audio chunks being handled as they are processed.
-
also you need to be careful to only auto-split on the correct markers.
generic markers, when auto-split, drop data and cause SBE
track splits, when auto-split, don't drop data and dont cause SBE, if you quantize to the sector (or something like that in the option)
-
i'm referring to dropping markers in post productions, i.e setting tracks.
not live, but if you are talking about dropping the markers, live.
it seems like a buffer rearrangement would work best.
sorry i didn't realize it was live tracking

Is that Foghorn Stringband? I want a copy! Good friends of mine. :0)

Very cool! Ya I'm an old Calobo groupy. lol Foghorn brings it everytime. Maybe we'll meet sometime. Cheers. +t for the oldtime love!

Towards the end of the festival my recordings all had crackles in them and were rendered useless.
Dont write them off just yet. See my post
here (http://taperssection.com/index.php?topic=57233.msg786281#msg786281) for an example.

Second screenshot is going to have to wait until tomorrow a.m. both of these occurences happened right at the 58 minute+ mark. I never would have figured out the first snafu if It didn't happen a second time. Now on top of it an audio engineer was telling me that my recording from last February for a DVD project had 'dropped frames' and went out of sync with the video. Man, it is all making sense now....
EDIT: to say that in the screenshot below the top stereo pair is hte AUD source and the lower pair is the SBD/JB3
you may want to render some gain off those stereo channels...

I agree, you want to drop 6db off each channel before combining in a matrix.
