Dropouts in sonar

[wang191]

I have been testing out sonar3, and after about a min the audio stops recording and it says drop out. So i increased the buffer and enabled write caching and it did a little better but i was still getting drop outs.

So i switched the HD that i record audio files to and i got 10 min of audio with no drop outs and that's as far as i let it go, but it seemed to do better. The problem is that the drive that seemed to work better was the drive with windows on it. I really wanted it to be recording to the Raid HD's.

I figured I would set up the computer with a raid 1 setup so if an audio drive died i would still have the audio i was working on. If I record to my windows drive and it dies, well say good bye to the project.

Anyone have any ideas on how to get this to perform better.

P4 2.8ghz (800mhz fsb)
1gig ram
1 WD120gig ide 7200rpm 8meg cache (windows drive)
2 Maxtor 120gig SATA 7200RPM 8meg cache (audio drives) Mirroring Raid 1

Any ideas?
Thanks guys.

hmm i don't know much about raid at all but what i do is just record to my main audio drive and when i am done i create a bundle file and save it to my extra drive. I update the bundle file once in a while to keep it current.

What's your soundcard? Incidentally, my Aardvark specifically says not to enable Read or Wite caching.

What is your I/O buffer size set to under OPTIONS-AUDIO-ADVANCED? The default is 64 which is way to low for most modern hard drives. Increase this to 128, 256 or 512 and see if that works any better for you.

If that still gives you grief, please give more details about your sound card and the driver mode you are using to address it.

Ciao,

Q.

Minofifa - are you the same 'Dar' that I've seen on the Line6 forums and The Watering Hole?

Also, which drivers are you running for your sound card?

If you are running WDM drivers, re-run the wave profile.

If you are running ASIO, check was Q said and see how you go.

Oh yeah. I'm running the Motu 896HD and wdm drivers. I have run the profiler a couple of times with different settings. Trying 96khz down to 41 and still get the same results. I tried the write cache to see if i could get it to not under run but that didnt work (obvioulsy).
I am running the options pretty much straight out of the box. I mean i changed sample rates and i changed the bit rate to 24. Everything else is pretty much what it came as.

I'm also not monitoring the inputs through the computer. I have set it up via motu's unit to monitor directly through the unit rather than put the strain on the cpu.

What i did notice on the last drop out I had was that the last second of audio was jittery and kinda repeated itself. I just un raided my hard drives to see if it does the same thing when the hard drives are just run normally. Not really solving the problem but more of a work around.

I would like to get the raid to work so if there's a settig i'm missing i'll rebuild the raid and see if i can get it to work with whatever settings you think i should try.

Thanks
