the time, so you can try just pressing "OK" and listening to the result. If it is
not correct, however, you can use the options in the dialog to try some
other possible encodings.
At the beginning of your imported track(s), you may notice a little bit of
noise. This is probably the file's header, which Audacity was not able to
parse. Just zoom in and select the noise with the Selection Tool, and then
choose Delete from the Edit Menu.
Edit ID3 Tags... - Opens a dialog allowing you to edit the ID3 tags
associated with a project, for MP3 exporting.
Quick Mix - This command mixes all of the selected tracks together. If you
are mixing stereo tracks, or mixing tracks that are marked as Left or Right
channel, the result will be a stereo track (two channels), otherwise the
result will be mono.
Your tracks are implicitly mixed whenever you hit the Play button and
whenever you export. This command offers a way to do it permanently and
save the results to disk, saving on playback resources.
Note that if you try to mix two very loud tracks together, you may get
clipping (it will sound like pops, clicks, and noise). To avoid this, drag the
gain slider on the tracks down to reduce their volume before mixing.
New Audio Track - This creates a new empty Audio Track. This command
is rarely needed,since importing, recording, and mixing automatically
create new tracks as needed. But you can use this to cut or copy data from
an existing track and paste it into a blank track. If that track was at a non-
default rate then you may need to use Set Rate from the Track Pop-Down
menu to set the correct sample rate.
New Stereo Track - same as above, but creates a stereo track. You can
also create a stereo track by joining two tracks using the track pop-down
menu.
New Label Track - This creates a new Label Track, which can be very
useful for textual annotation.
New Time Track - This creates a new Time Track, which is used to vary
the speed of playback over time.
Remove Tracks - This command removes the selected track or tracks
from the project. Even if only part of a track is selected, the entire track is
removed. You can also delete a track by clicking the X in its upper-left
corner. To cut out only part of the audio in a track, use Delete or Silence.
