The Center Channel Extractor does an okay job, but it is limited depending on how the song was mixed.
You may also want to try using the Spectral Frequency display, or the Pan display modes to help determine what degree the clips you want to isolate are from center, or to determine their frequency range, which can help get higher quality extractions. You might also have some luck using the Frequency Band Splitter in Multitrack which lets you slice a single file into several separate files at very specific frequency ranges.

Audition 1.5 should work with most firewire devices, although it did not support ASIO, so you’ll need to use the WDM drivers if your device has them.
Open Audition and click OPTIONS then DEVICE ORDER. Click the RECORDING DEVICES tab and make sure that your Firewire device is displayed there and listed on the right side. You can also make sure it’s at the top of the preferred device order list, and set to be used in EV (Edit View as opposed to just multitrack view.)

Audition 2.0 implemented support for the Panning Law on the master output, which can be disabled in the Preferences under Multitrack->Stereo Panning Mode.
Panning Law, if you’re not familiar, is the term used to describe the behavior of mixing consoles when a track was panned hard left or right, as compared to centered. The amplitude when panned hard was quieter than when centered, due to linear gain increase/decrease on each channel to simulate the pan. When centered, both channels played at full gain, giving an apparent +3dB gain as opposed to hard-panned to one side. There’s an excellent explanation of this over at Harmony Central: https://www.harmony-central.com/articles/tips/panning_laws/
This shouldn’t be an issue when creating new sessions, but you’ll definitely notice it when importing sessions from 1.5. Changing that preference setting should prevent this from being an issue.

Hi norrumba,
That is a weird problem. Built-in laptop drives are rarely the pinnacle of high-end audio hardware, but they certainly shouldn’t behave like that!
My first suggestion would be to see if the same behavior occurs when using a different audio device. If you have access to or can borrow a USB sound device of some kind, it would be interesting to know if the same problem occurs when playing back through that. If so, we can feel certain the problem lies in either the application or the system at this point. If not, then it’s definitely like that the laptop sound device is the culprit.
If it turns out to be the laptop’s audio, there may be some settings in the audio control panel that is affecting this. A lot of these have special features like 3-D Sound enhancement, Spatial settings, etc, that are generally horrible. I’d recommend checking for, and disabling any of these, so that the sound that comes out the headphone jack is as pure and untouched as possible. Audition 1.0 didn’t yet have the concept of a master track, so it’s not an issue of having some pan or effects settings hidden at the end of the chain.
I’d also suggest, as a quick test, starting a new session, importing a few of the audio tracks from the old session, and doing a quick mix test to see if the problem still occurs.
Good luck and please let me know the results!

Hi Maldazaar,
When you checked the video’s header information in G-Spot, which codec did it say the video was compressed with? I’ll try to find or create a similar file here and see if I can help find out what’s going on.
You’re probably aware of this already, but AVI is simply a container format for video files, and the individual audio and video streams within can be one of thousands of different codecs – not all of which Audition is able to support.
-
Did you already get this figured out or is it still an issue? What format AVI are you exporting from After Effects? Just a standard DV-AVI?
I agree that it does sound like a sample rate issue, but I haven’t seen anything like that occur before, either. Most of the video export work is done in Adobe Media Encoder, which is the same tool used in Premiere Pro and AE.
Here’s a quick question – you import the video into Audition and insert it into the multitrack editor. When you do this, does it spend some time conforming the audio before it shows up in the Video track? (I know there’s no audio in the video clip, but AE may be simply exporting a silent audio track as opposed to no audio stream at all.)
In fact, you may want to try exporting from AE once more, and enable the option to export audio, if possible. The track will be silent, and you can strip the silent audio track out in Audition, but it may help make it clearer if there are sample rate conversion issues.

Hi all,
Sorry for my absence. Getting busy around here as we’re wrapping up work on some stuff.
Audition does run on Vista, although it turns off the Aero interface if you’re using that. Once it’s closed, Aero is re-enabled.
If you’re using Vista and doing ANY performance-sensitive work (such as recording, video editing, etc) I highly recommend changing to the Basic Vista theme and NOT using Aero. We’re seeing really incredibly poor performance problems with it on – some really random USB bus issues, screen drawing issues, etc – even using Windows own libraries on some pretty beefy systems.
I haven’t spent too much time with 2.0 under Vista – but enough to say that it runs fine. The biggest problem is a new lack of drivers – a lot of the ASIO drivers that worked great in XP do not work or only partially work under Vista. Vista also changed the way applications see device channels, so you may notice some weirdness when setting up recording inputs.

The Layla cards are great, and is one of the main devices we use in our studio lab. It should absolutely be able to handle a nice chunk of tracks without problems. I would suggest going into Edit -> Audio Hardware Setup and making certain Audition is configured to use the Layla’s ASIO driver from the manufacturer, and is not defaulting to the “Audition Windows Sound” wrapper, which is a band-aid for older cards and will give nowhere near the power or speed of the Layla’s native driver.
As for the installation issues on the 64-bit system, when it reaches the point of asking which language you’d like to install, does it just disappear? Or is the failure to install a little more or less graceful? We can troubleshoot it back and forth over these forums, but I’d strongly recommend taking advantage of the free installation technical support Adobe offers at 1-800-642-3623. Those guys are on top of it and know just about every little problem that comes up during installation. I’m good with the application itself, but they know the installer inside out, and if they can’t fix it while on the phone, will figure it out and call you back. I went down to their call center a year ago and was really impressed with the guys working the phones for us.

Willie’s suggestion should solve the problem very well. If you find that it’s still an annoyance, you can change to Spectral View which should show the humming noise as a bright, horizontal band across the file. Use the Marquee tool to select this region and then either delete it, or reduce it’s volume.
You might want to download the Public Beta of Adobe Soundbooth from https://labs.adobe.com/ as well. There are new tools that make these tasks much simpler such as a horizontal I-Beam selection tool, and automated noise reduction tools. Our next public beta will include more comprehensive Noise reduction, more in line with the power found in Audition’s tools.
Good luck!

Hi creatureteacher,
I’m not overly familiar with Avid, but perhaps you’re saving the file as a 32-bit WAV. I’ve found that 32-bit WAV and AIFF support is not handled the same in all applications. Maybe try exporting the cleaned-up file as a 16-bit WAV and see if Avid can import that properly.
