Auditon 3.01 input latency
Hello folks!
Perhaps I don't use the right terminology, but my issue concerns the INPUT DELAY when you record a track in audition. Not the playback-latency or “listening”-latency.
Some months ago I purchased a new DAW with Windows 7 64-bit, Intel Core i7 processor, 8 GB RAM, a Corsair Force SSD-hard drive for the programs, a WD Velociraptor hard drive for “working disc”, and a Infrasonic Quartet 24 bit/192 kHz PCI-soundcard.
I disabled the onboard soundcard and installed Audition 3.0 + the 3.01-updatefile on the DAW. So there’s nothing else running on the computer than Audition, the soundcard-driver + of course all the Windows OS-programs and services. But nothing else, like antivirus, firewalls etc., because I don’t have the computer connected to the net.
Everything seemed to be ok. All my vsti/midi systems worked fine, all microphone/line inputs worked, playback worked…. so I started to record guitar-tracks using direct monitoring, playing with midi drums- and bass-tracks.
The monitoring was ok. No latency or delay on my guitar-monitoring while playing, since I heard it directly from the soundcard.
But when I listened to the recorded guitar-track, it sounded “badly played”. No so much that you can put a finger on it, but enough to sound “odd and strange”.
My first thought was that I’m just getting old and rusty, but anyway I started to do some tests to see if there’s something wrong with the system devices and setups.
The midi-tracks and vsti:s was ok = they play exactly in beat. No delays.
But when I did a “loopback” test on the analog output-input signal, I noticed that there was a delay in the signal.
I’m not much of a technical person, so it’s very possible that I’m thinking totally wrong, but I did it in this way:
I opened a new (44100kHz/32 bit) session with only one audio-track, tempo 120 bpm, 4/4 time, 4 beats/bar, external monitoring and the soundcards buffer on 64 samples. I enabled the metronome and putted the metronome output to “01S” (the same as the sessions master-output). I putted the audio-track input to “03M” (the input I use from the soundcard) and putted the audio-track-output to “None”.
After that I putted an audiocable from the soundcards output jack to the soundcards input jack. If I’m thinking right, I was now recording an analog metronome-signal into the audio-track in the session, which should be in beat with the internal metronome.
But when I display the view in “bars and beats”, open the recorded metronome-track in edit view, mark the exact place for beat one in a bar, change the view to “decimals (mm.ss.ddd), and zoom in the marked place/section, I noticed that the metronome “hit” is about 6 ms after the mark.
So there’s a delay in the input signal. The input/recorded signal “arrives too late” into the track.
Ok, I was thinking that “6 ms isn’t so much”….perhaps it’s normal in DAW:s?…..”but the delay should be only 1,45 ms with 44, 1 khz and a 64 samples buffer”…”but perhaps I have to live with it”…..
But even so, I decided to do the same test on my old DAW. A Windows XP 32bit with the same Audition 3.01., AMD Athlon 64 3500+ processor, 1,5 G RAM, 7200rpm hard drives and a Lexicon Lambda usb-soundcard.
I was surprised when the delay was nearly zero with a similar “loopback”-test. Even if I used a 512 samples buffer, it was only around 0,5 ms late.
This must be the reason why I never had similar problems with my old DAW.
But what can be causing this on my new DAW? Of course there can be thousands of reasons, everything from conflicting IRQ:s to bad drivers, but I have to start to rule out the reasons one by one.
I have noticed that the Infrasonic Quartet card isn’t so well-known and common, but if we talk only about other possibly factors that can cause this problem, I could ask these questions:
-I have understood that Audition 3.01 doesn’t have any “automatic latency correction”? Am I right? If it after all has one, can it be that it works in Windows XP 32-bit , but not in Windows 7 64bit?
-Anyone know if the Lexicon Lambda has this “automatic latency correction”?
Of course I’m grateful for any ideas, tips and hints that could help me solve this problem.
( ….and to make this case even more complicated, I cannot try how the Lexicon Lambda acts on the new Windows 7 DAW, because the drivers I downloaded from Lexicon won’t work at all in this new setup. That could have explained much.)
Cheers!

Re: Auditon 3.01 input latency
Hi Peter and welcome.
Someone smarter then me will no doubt come along with a slick answer but before they do a quick question or two -
1. Do you have a 7200rpm drive in your system as well as the Raptor?
If so try recording to that and see if its the same
2. If its better with the 7200rpm then next question - is AHCI enabled in the bios (do not enable now if it isn't)?
BTW 6 ms is pretty well not much

Hello Runaway.
Thanks for the fast aswer! Well...you sound pretty smart. I think you got something there. Sounds a little odd, but is it possible that my drives are TOO FAST? I don't have a 7200 rpm drive on my system, but I connected a Maxtor external USB-hard-drive to the system, and recorded a "loopback" testession on it. The latency was only 4 ms. I'm confused.... Can it be something wrong (thinking) with my setup and drives? I have the Audition program on C-drive, which is a Corsair force 115 GB SSD Sandforce harddrive. And all the sessions and audio on D-drive, which is the Velociraptor 450 GB 3,5" SATA 3 10 K 32M.
I could'nt see anything in the bios concerning ACHI and the Velociraptor. Under AHCI there is only the Corsair SSD drive, and the setting is [auto]. Any ideas?
Well...6 ms seems to be too much for me, when I play with exact midi-plugins. And... if the latency is 6 ms everytime you record the next track (if you listen to the previous), you will end up with 60 ms after the 10:th track.

Re: Auditon 3.01 input latency
Are you using the ASIO drivers with the Infrasonic sound card?

Sure. The Audio Hardware Setup in Audition says: Audio Driver: ASIO 2.2 - QUARTET.
I had some problems finding the right..or should I say, the best working driver. I downloaded the newest driver from Infra-Sonic (ISQUARTET_V1.24.10), but I had problems with it. The best working driver is the one that came with the card (ISQUARTET_V1.22.03). But I have tried both, and the latency(problem) is similar.

Re: Auditon 3.01 input latency
One thing you can try is to turn off any Windows 7 stuff, like Aero, which would use resources.
Go to Control Panel>Performance Information and Tools, and in the left column click Adjust Visual Effects. A window will pop up. In the Visual Effects tab, choose Adjust for Best Performance. Then in the Advanced Tab, choose Programs under the Processor Scheduling section.
This will turn off the Windows Aero visual stuff, freeing up some computer resources. Not sure if it will help your latency problem but it should be done anyway if you are using this computer as a DAW.

Hi Eric!
Yes, I have the "best performance" option chosen in Visual effects. About the Advanced tabs options there are different oppinions. Others say that a soundcard is a "Background service", so for best performance is better to choose this option. Anyway, I have tried both options, and it makes no difference.
Since we are discussing these performance-settings, do you have any suggestions about the Virtual memory settings on this same tab?

There is a known issue with Raptor drives and standard IDE setup rather than AHCI
The result is a performance issue and as your audio is coming off the raptor then I would be looking here to make sure it is set on.
IMPORTANT: You need to make a registry entry before switching it on - google can be your friend in this area
Do a search for raptor & ahci
There may be other issues but at least check this one out
