 Posted: Fri Oct 04, 2013 10:42 pm Post subject: Audition truncates peaks above -6 |
 |
|
At one time I knew how to fix this problem but haven't had the issue in 2 or 3 years. I forgot the fix.
Used an older computer today with Audition 3.0 in place. All sound peaks above -6 were truncated. What kind of happy-dance do I do to stop this foolishness?
My memory (fuzzy as it is) thinks it has something to with switching between mono and stereo. (I'm working in Waveform, not Multitrack. |

There are a couple of thoughts on this very subject which come to mind.
One: please check your settings from the soundcard? How are you connecting from the interface to the computer? Are your outputs set correctly (±1,_10?)?
Two: please look at your AA settings. Have you reset the DC offset?
I am not going into the details of these issues, for brevity. However, each of these issues are prime candidates for causing trouble as described.
Good luck on your troubleshooting issues.

Thanks for the link. Reading through the messages supported the hunch/theory I had begun working on here. I think it has to do with sound card set for stereo while asking Audition to record mono. (and maybe the other way around also!)
I usually do what I assume most others here do: Get things working... and then leave them alone. But NO! I had to get worried about maybe a little too much background noise so I began experimenting. Just to be able to measure how much of a problem it is having my computer in the room, I went downstairs and stole the little netbook machine and brought it up to the studio, plugged the USB into it and started recording so I could power down the big machine and measure the change.
Add to that the recent acquisition of the RE-20 which has a lower output (a topic which we have discussed at length here lately) and now experimenting with the Cloudlifter CL1.
It appears to be doing what running theories through my brain thought would happen. Without the boost of the CL1, the room noise come down to about the same level as the internal noise of the A/D converter. Bumping the output of the mic up about 15 dB now allows me to work on the room noise separately from the white-noise like buzz in the audio chain.
With the room noise now down close to the "forget about it.... that's low enough" range, that puts the equipment generated hiss down in the "and why are you worrying about that" range.
Hopefully this week I can set everything and pour concrete or something over everything so I never touch a gain control or other setting again.  |

I was composing the long reply when you posted. Thanks for the checklist.
In the past year I have migrated just about my entire set-up from 'junk-yard refugee components' to new stuff at the low end of what is acceptable for voice-over work.
AT4033CL sitting in the box now while RE-20 carries the water. The RE-20 gave me a 9 dB improvement on signal-to-noise. (There is a simple explanation why that works. RE-20 doesn't reject the noise any better than the AT4033. It just tolerates close talking so voice arrives 9 dB louder than when giving the condenser mike some distance.)
Switched from internal sound card I have used for years to a PreSonus 22VSL. As of yesterday I am still scratching my head over that one. That was the reason for my post asking about the RME and Digigram hardware. I think the PreSonus is going to be fine for now.
Moved from Audition 2.0 through 3.0, 5.5, 6.0 and now Audition CC. Too many settings in too many places that work too differently.
As of bedtime last night, the AA3.0 on the netbook was back to working correctly. The key seems to be going into HARDWARE PREFERENCES and matching up mono or stereo outputs and then when opening a file, open it to match (mono or stereo).
And why did I ever-on-earth mess with the stereo concept? I've got a dummy pad plugged into the Right Channel Mic Input and I did test recordings in stereo so I would have a Noise Reference Level in the right channel to compare to the noises in silent sections of the left channel. (I know. I've been watching too much CSI on TV.) |
