Adobe Auditio multitrack wavefile too small

Hey John, this may not be the ideal solution you are looking for, but Audition does have a volume adjustment button when you are in multitrack mode. Adjustments to this will raise/lower your levels in multitrack, but it will not affect your original file.  But yeah, Steve is spot on in his recommendations.  Hope these tips help. 

I'm afraid that whether you think so or not, your levels are low. Indeed, very low. To the point where, if you aren't careful, you'll be introducing system noise by recording at such a low level. What you see in Multitrack is a pretty accurate representation of the level of the file you are looking at. It's perfectly possible to fix this by using Normalize on your exisitng file in Waveform view - just normalize it to about -1dB. This will amplify the file to a more acceptable level, and this will be represented a visible waveform in Multitrack.

But really what you need to do is figure out how to get the correct levels recorded in the first place. You can monitor the incoming levels easily (right click on the meters and select Monitor Input Level) and you need to set this so that when you are speaking normally, the signal peaks at around -12dB. This will leave you enough headroom, so that you don't hit 0dB at any point - that would be an overload. If you record like that, your waveforms will appear to be visible without having to normalize them.
