Completely incorrect.
If you record in
mono you will get the sound from both speakers/headphones, subject to the "pan position".
The most common reason that people get sound out of only one speaker/headphone when recording with one microphone is because they have recorded a stereo track and the microphone has recorded only on one channel (one side) of the stereo pair.
In Audacity 1.2.6, go to;
"Edit menu > Preferences > Audio I/O tab"
Set the number of channels to "1 (mono)"
Record with your (one) microphone. This will create a
mono track.
Play it back and the sound will come out equally from both left and right.
-------------------
Pan position:
If you
want the sound to come more from one side than the other, there is a "pan position" slider on the left side of each recorded track.
There are a total of 2 sliders on each track. The upper slider is a volume slider (marked "-.....+"). The lower slider is the "Pan position" slider (marked "L....R").
If the pan slider is moved to the left, the sound will come more from the left speaker/headphone, if moved to the right it will come more from the right.
Why you may want to use the pan slider:
Let's say you are recording 2 guitar tracks and one vocal track. If you have 3 people performing live, you would probably have one guitar to the left, one guitar to the right, and the singer in the middle.
With 3 mono tracks, you can move the pan slider on one guitar track a little to the left, the pan slider of the other guitar a little to the right, and leave the vocal in the middle. You can also use the volume sliders to adjust the playback level of each track. When you "mix down" the recording (either using the "Project menu > Quick Mix", or when you Export your finished piece) the tracks will be mixed to stereo and you will hear the instruments "spaced out" in stereo, like in real life.
Words of caution -
It is usually best to avoid panning tracks too far off centre as it can sound very weird.
Take care not to boost the volume of the tracks too much or you will get distortion occuring.
