You should have, or be able to display, a “line in” fader for source selection and level control also.

The soundcard’s mixer application or the windows mixer should enable you to set the soundcard correctly – what soundcard is it?

The advice on Adobe’s site is –

“n any version of Windows that you have:
– Dbl-click on the yellow (or grey) speaker icon located on the lower right
hand corner of your screen.
– Select Options, Properties.
– In the “Adjust Volume for” area, select Recording.
– This will show you all the devices you can record from, in the
“Show the following volume controls” window.
– Make sure all the devices have a check mark in them.
– Click on OK.
– At the bottom of each recording device, there is a check box
with “Select” to the right of it. Use this to select the recording
device that you want. (if you’re recording from Line In, choose LINE. If you’re recording from Mic In, choose MIC, etc)
– Make sure the recording Volume is at least half way up.
– Minimize the “Recording Control” window.
– You are ready to record.

Now, if you still have bleed, it’s possible that you’ve either selected something like ‘WAVE’ for your input device, or perhaps ‘Mixed Output’ or ‘What You Hear’. The latter settings essentially lump ALL audio fed through the soundcard into Adobe Audition. The ‘Wave’ setting will do exactly what is described above – cause the playback track to be recorded with the overdub track.

If you’re using a more pro-level card, chances are it has it’s own mixer panel (and thus, is not controlled by the Windows Mixer).

The usual problem is that the soundcard mixer has been set to record “what you hear” or “wave mix” or the like, not the specific input in use.

Are they variable bit rate files? That might be the cause.

[Ozpeter]

No, the new behaviour is fixed. Whatever is the topmost clip gets played, which you can manipulate with the right click option “bring to front”. Though if you set the clip attribute “play hidden clips” it will do just that, which can be essential if crossfading two clips on the same track.

Is your problem one of file management, in other words, the new arrangements create a lot of clips you don’t want? If so, the best way to manage seems to be to use the “remove hidden clips” option, which takes all clips apart from those on top out of the session. Then use “save session as…” and tick the box which says something like “save copies of all associated files”, saving the whole thing to a new folder – but not the clips you are not using. Now that’s actually a good backup routine – you’ve now got your original folder with its full set of clips, plus the new folder with its only-current set of clips. Tomorrow, work on the version in that new folder, and at the end of the day, repeat the creation of a backup, and delete the original folder – hopefully by now you really don’t need any of those unused clips. Continue in like fashion. So you will always have a backup in a different folder, and you can always go back to yesterday’s takes if you suddenly realised you did want one of them.

Hope that essay helps…

The two versions use different “peak” (.pk) files so loading times could increase.

[Ozpeter]

Normally you’d be thinking in terms of working in 32 bits and saving in 16 bits. 8 bit files are inherently noisy. If you noise-reduce an 8 bit file, it’s a bit like copying a olde-worlde cassette recording into your PC, getting rid of the tape hiss there, then copying it back to the cassette – at which point the cassette hiss will come back. 8 bit recordings are probably somewhat worse than cassette recordings, noisewise.

https://studio.adobe.com/us/tips/tip.jsp?p=1&id=686&xml=aud15freqedit contains some relevant guidance.

Don’t understand that. In Audition 1.5 or 2.0 it’s easy to use the spectral view, draw a little box round the thump, and delete it. Then replace it with thumpless nearby audio if you want. I’m pretty sure there is a tutorial on the Adobe site showing this method. I regularly use this method with plosives caused by voices too close to the mic.
