Recording glitch

Hi, not sure how ro describe/call this or what its related too but hope someone here can help.

We are using Audition 2 which until recently recorded fine.

Tried recording today and at about 16 seconds or so the recording becomes slightly distorted and also has a duplicate take as if a delay.

Would this be related to latency?

It occurs for about 5 seconds or so and then corrects itself.

Nothing has changed either with the PC or setup.

Using a Soundblaster Audigy for input taken from a Sonifex mixer. The PC has a second soundcard (Audigy 2) used for playout of audio to the radio studio.


Any help or advice appreciated.

Searched through the forums and came up with the most likely answer and it worked.

Reduced the buffers as low as the soundcard would allow (512), this stopped the delay then also turned down the input gain to remove the distortion/clipping.

Could not get Audition to record though with the Creative ASIO drivers which would allow turning the buffers down even more.

The Creative ASIO drivers are known to be flawed. So they're like pretty much anything else with the Creative name attached...

Cheers Steve, can anyone suggest a sub £100 usb soundcard available in the UK?

Thanks toneranger33

Before you go down that route, it may be worth trying the (free) ASIO4ALL driver. This converts Audition's ASIO input/output back to WDM, and the Creative WDM driver is something of an improvement over their ASIO one - although this won't particularly help the latency figures, I must admit.

The other advantage of ASIO4ALL, though, is that it will enable Audition to handle more than one soundcard at the same time (direct ASIO drivers won't let you do this - that's a limitation of the system). So if you want to use two cards in your system anyway, then this can save the need for any system resetting.

Hi Steve, still having problems with this.

We decided against installing ASIO4All as we thought we had solved the problems. Changing the buffers to 512 (as low as the card would allow) and adjusting the gain solved the delay and clipping but now we suffer audio dropout. It starts around 8 seconds and then every 3 seconds or so before correcting itself before returning later during the recording.


Anymore ideas and advice would be appreciated.

We are running XP Home SP2, 2.4ghz with 1 gb ram. No other audio software is running at the same time. The other strange thing is no of this happens in Audacity on the same PC.

Turn off any antivirus software, wireless network cards and automatic updating software when recording in Audition.  Those can easily steal resources from your computer that Audition needs.

Hi Eric, thank you for the tip - all done previously.

Kind Regards Tony

It's a couple of long shots - but try defragging the drive, and also get hold of a copy of EndItAll (or something very similar) and try running that before recording - it will close all the services running on the machine that don't need to be, and that are squandering your resources.

Hi Steve, already defragged the drive  but will give EndItAll a try when next in the studio (next week now).

Its strange I'm also running Audition on a second machine with  lower spec (1.8 ghz/1gb ram/onboard sound and all is fine).

Kind Regards tony

Still not tried enditall as we are loathe to install anymore software when everything else is running OK.

When recording droput occurs at 6.93 seconds and picks up again at 6.97 seconds. this pattern repeats getting progressively worse with distortion.

Audacity records just fine.

Does this 2nd PC have 2 soundcards installed as well?

No just onboard sound.

Thanks to Bruce Williams at audio2u.com for the tip about sample rates.

Recording at 32000 is fine as is recording at 48000, however the dropout occurs when recording at 44100.

Sounds to me like a hardware problem.

Strange that it should start a month after using the card which no problems. A decent soundcard is in order.
