Yeah, but you can change that.
You record 10 minutes and hit stop, let's say. Then you save your project. Now you're relaxed; if your computer crashes, those 10 minute are saved.
You're ready to record again. Click your cursor at the end of what's recorded so far, right in that last track. Now hit record, and the next track begins where that one ended (instead of at 0 seconds).
Later, you have 5 tracks, staggered beautifully, and you would love them to be one track, please. Highlight them and hit Edit > Quick Mix. But do be very careful that you don't have overlapped tracks before you do that. You would be sad.
Suppose you have 4 beautifully staggered tracks but the 5th track started at the beginning of track 4 because you forgot to click that time at the end of the track. Look at the little icons in the sort of upper left corner area of Audacity. See the icon with double arrow and line <--->. Highlight that tool and click on the unstaggered track and drag it so its beginning lines up under the previous track's end.
There. How was that?
While I'm here... I'll tell you my favorite how-to-boost volume trick:
highlight your single track after it has been edited, choose Edit > Duplicate, and you suddenly have two identical tracks and a very nicely boosted volume. Need a little more? duplicate again.
And then there's input volume. That's very important. So here's a bit about input levels.
On a newer PC* it's
Start > Control Panels > Sounds and Audio Devices**
and then you get a window, "Sounds and Audio Devices Properties"
Click the "Voice" tab in that window
and select your microphone in the drop-down menu for "Voice recording"
if it's a headset, select it also in the "Voice playback" menu
click the "Volume..." button (for each) and adjust
*On a PC "classic Start menu" it's
Start > Settings > Control Panel > etc.
[**or Sounds, Speech and Audio Devices > Sounds and Audio Devices]
On a Mac OS X, it's
Apple icon (upper left corner of screen) > System Preferences... > Hardware > Sound
In the "Sound" window that opens, under "Choose a device for sound input," highlight your mic/headset. Then adjust the volumes.
It's prudent to check the levels at the beginning of each record session and after any interruption (e.g., computer crash = interruption).
