Audio Dropouts on new x79 build ..New to Audition..

Tags: #cs5.5 #recording #latency #audition #multitrack #playback_issues

OK here goes: I just built a shiny new monster with cs5.5 production premium. Adobe and after effects run strong and fast. But I can't even listen to a single track on Audition with out playback skips or very short drop out (the audio drop also loses musical time). I also noticed if I make a selection in multitrack while playback is going it will also drop out for a split second but stays in time. I can only change latency since I don't have any core audio or asio drivers. My realtek audio chip sucks?? I have all the newest drivers and firmware on EVERYTHING. This machine is now flying seriously. My specs:

 

I7 core 3930k hexacore processor with 12mb L3

asus p9x79 deluxe

corsair h80 water cooling (temps all great)

stormtrooper case

cooler master silent pro 850watt PSU

EVGA GTX 580 3GB

2 x Seagate Barracuda ST2000DM001 2TB 7200 RPM 64MB Cache SATA 6.0 Gb/s 3.5 in RAID 0 on Intel controller (SATA RAID mode in UEFI BIOS)ports 4 and 5, GPT Basic Disk, 128 sectors , and 64K Allocation Size

2 x Seagate Barracuda ST2000DM001 2TB 7200 RPM 64MB Cache SATA 6.0 Gb/s 3.5 on Marvell Controll ports 0 and 1 (ACHI mode) GPT Basic Disk

1 Corsair Force GT 180GB SATA 6.0 Gb/s SSD (OS and APPS) on Intel Controller (non-RAID member) port 0, MBR Basic Disk

Lite-On Blu Ray Burner Intel controller port 2

(nothing on intel controller port 1, 3)

UPS and Line conditioner

ACER 27" 3d Monitor, and 24" second monitor in extended display

Microsoft Keyboard Wireless 2000

Microsoft Wireless Touch Mouse

Logitech Rumblepad

32 GB Corsair Vengeance 1600mHz (8x4GB) Mem tested with multiple passes..running @ 1333mHz for stability

Adobe CS5.5 Production Premium

Microsoft Security Essentials (only virus protection installed)

2 Games installed (Batman Arkham City and Skyrim Elder Scrolls)

Acronis Home True Backup

Roxio Creator Pro

All updates for drivers, firmware, software, for EVERYTHING(motherboards, drives , video card...)

system hibernation off

OS drive has trim support working, (no page file and no libraries)

Page file manually managed on one of the seagates on the marvell controller (not the raid) on its own partition first thing created on the drive

on that same drive I have the mp3's I used in the Audition session .

I have Audition using the Raid 0 for the temp.

The session was a multitrack with 3 different mp3's on one track cut down and crossfaded only 4 or 5 cuts total I threw on a reverb from audition for shitsandgiggles

the problem happens sometimes anywhere, but always when:

letting the track play for a indeterminate length generally more than 20 seconds then right after the cut (and switch to different mp3 file) a slight pause dropout

...but If I playback from insertion a little less ..say 5 seconds from cut... immediately afterwards... no dropouts

then sometimes playback just stops for no apparent reason @ anywhere

Also, during playback if I change the parameters of the reverb plugin..it takes about 1.5-2 seconds until the playback of the new parameters can be monitored.. Is this the normal for cpu based audio recording as opposed to DSP chip based (my old protools tdm)

I didn't know if I am going to have to buy a sound card with core audio or asio drivers to solve this???

My Goal is to leave my MAC 9.2.2 dual 1.0gHZ with 1.5gB ram and a scsi iii atto card with 24mixcube (one mixcore,two mixfarms)Pro Tools 5.1.3ce purchased in 2002 that records 16 Tracks flawless no glitch no dropout with realtime effects multiple reverbs ,24bit 48k while playback another 16 tracks.

 

I would like to be able to record 16 tracks @ once.. maybe MOTU 896 Mark3 hybrid and a MOTO 8pre... maybe playback  8 tracks while recording 16 and listening to all 24??? With some realtime dsp processing (non destructive)...

What the heck? Premiere Pro is smoking 4 layers of avchd with color correction and realtime dissolves and titles and overlays smooth like butter..

 

I can't even get 3 mp3's on a track without dropout out of Audition. I've tried every choosable latency in preferences. Can I get ASIO drivers for my realtek onboard HD audio chip?? Am I asking too much from my system for the 24 track count with no glitches or dropouts?? Should I put the system page file on another drive than the drive the audio is residing on (or audio would be written to)? I have most startup processes disabled through msconfig..should I get some kind of process killer and if so, the name of  a good free or inexpensive one?

Thanks in advance for any feedback!

    Okay, I have no specific fix for you but I can tell you that my 4 year old laptop (nowhere near you in terms of spec) frequently records at least 16 simultaneous tracks (I've tested up to 32, my theoretical maximum but never done it in anger).  I also frequently mix sessions in the 24+ track range.

     

    Now, a few general system killers:  having any form of wifi enabled can be a pain, as can having anti virus software turned on.  I completely shut those down before doing any serious audio work.  Beyond that, there are numerous "optimise your computer for audio" sites full of tricks.  It's worth working through the hints.

     

    Second, you mentioned reverbs.  Which one(s) are you using?  Some of them are a much higher processor load than others--I can't really use "full reverb" in realtime mode (but can either apply it in destructive mode or add it in multitrack and freeze that track).  Studio reverb is much more forgiving.  There are other processes as well that can be problematic in real time--most of them give you some kind of warning though.

     

    Finally, I'm not clear about what you want to do with your Realtek piece of rubbish (not being nasty, my laptop has the same).  I can use it for basic playback if not hooked up to one of my "proper" cards but I don't know of any ASIO drivers for it.  This means that the buffers have to be big and latency high when I use it--but for simple playback (I'd never use it for recording) this isn't an issue.  However, one workround that might help you would be to download Asio4All.  This isn't a true ASIO driver but, rather, an ASIO wrapper for MME devices.  However, it's got a lot of people out of trouble with things like this.

     

    ...and a final finally:  you asked about a process killer.  I don't use it often, but, when I need one, I've had good results with one called "EnditAll".  It takes a bit of setting up but seems to work well.

     

    Hope at least some of this waffle helps.

    You don't actually mention in your spec what operating system you are using but I would guess Windows 7 in some form. Win 7 is notorious for messing with audio using the normal MME drivers and setting the sample rate to something other than the one you require. Could be this causing the interruptions and glitches when switching between files due to the OS trying to convert the sample rate ( and making a nasty mess of it). Do yourself a favour and get yourself a decent audio interface with ASIO drivers which bypass the OS. It would be a pity to spoil the audio on such a super PC by just using the onboard Realtek chip.

    The other thing is that you may think you're playing MP3's, but in Audition you aren't. They will all be converted to wav files upon opening, and they'll be playing from temp files. The first thing I'd try is not using a Raid 0 drive for your temp files, but one of the other drives and see if it makes any difference at all - I suspect that it might.
