vertical zoom on audio without amplifying

Is this possible?
Quite often I have to synchronise two audio tracks that are very quiet (live sound recorded in different ways), and adding 50 dB through normalisation isn't an option. There's no time code - so I am assuming that I have to zoom in on the waveforms and synchronise them by visual alignment. I wish Sony Vegas Pro 11 had a feature where I could zoom in on a wave form vertically. I used to do the same job in Audacity quite easily - just click or shift-click on the y-axis scale to zoom in and out, then the sync is easy to do visually. In Vegas Pro, I have to muck around with temporary splits and amplifications, write down the horizontal shift, undo all that , then make a guess at the shift, and repeat the splitting and normalising to test. Is there a vertical zoom function? Is there an easier way to sync very quiet audio?

No vertical zoom, apart from widening the whole track. But how about Normalise, align, then denormalise ?

If I understand correctly, the OP wishes to vertically enlarge the waveform?
Zoom in/out (plus/minus icons) on the LEFT bottom of timeline. (Alt. shortcut: Ctrl. + mouse scroll wheel). The Zoom in/out on the timeline RIGHT bottom, are horizontal zoom.

Addendum: Sorry, you may want to disregard the above... I was thinking Sound Forge and can't currently check if the same applies to Vegas.
Sorry for any confusion.

Update: As Geoff stated, there is no vertical zoom in VP. (at least not like there is in SF). However, the bottom of the track header can be dragged downward to make it taller, that along with the horizontal zoom should be sufficient for syncing.

In VegasPro, SoundForge and CDArchitect you can increase and decrease (zoom) audio waveform height within the track easily with the same commands:

Shift+UpArrow = Increase height
or
Shift+DownArrow = Decrease height

hope that helps!
