| I've just downloaded Audacity and am new to editing music.
| What I am attempting to do is lay a voice track over a piece of music.
| The problem that I'm having is the piece of music is in a WAV fileand is
| about 30 mins long but when I import to Audacity it condenses it to
| about 15 secs. How do I get the track to play at it's normal speed?
There is probably some problem with the WAV file. Do you know what application
created it? It might not really be a WAV file, or it may be corrupted so that the
file length is being misread, or it may be a compressed file in a WAV container
and the compression is confusing Audacity.
If you are on Windows you could try dragging the file into this program
http://www.erightsoft.com/SUPER.html#Dnload
then follow these instructions to rewrite it to a standard PCM WAV file :
1) in the output container list top left choose "WAV (audio only)"
2) in the output audio codec list top right "WAV pcm 16 little endian"
3) In the "audio" panel select 44 100 in "Sample Freq" and choose either
"1 channel" if your file is mono or "2 channel" if it's stereo. If you do not
know, choose "2 channel".
4) Right-click > Specify the Output Folder Destination and choose a location
for the exported WAV that you can remember. Click "Save Changes".
5) Ensure the check box by the name of the file you dragged in is checked
then click "Encode (Active Files)". When a file size appears to right of the file
name under "Output Status", you're done. Exit SuperPlayer, open Audacity,
click Project > Import Audio, navigate to the folder you specified for
output in SuperPlayer, select the WAV file and click "Open".
If you are on OS X, or already have iTunes, you can use that program. Drag the
WAV into iTunes. Set the conversion format in iTunes Preferences at Advanced >
Importing: Import using WAV encoder. Then right-click or control-click over the
file and you will have an option to convert it to WAV. Then import the converted
WAV into Audacity.
If you have any further questions, please tell us what operating system you are
on (e.g. Windows XP, OS X 10.4, and if you are on OS X, whether it is an Intel
Mac or Power PC). Also please tell us what version of Audacity you are using
(see Help > About or Audacity > About Audacity in the program).
Underneath this message there are some tips on recording voiceovers.

****************************************************************
Enable "Play other tracks while recording new one" on the Audio I/O tab of
Preferences. This will enable you to listen to the tracks already on screen
whilst recording another one, as soon as you press the red "Record" button.
Your recording will appear on a new separate track and so it can be edited
independently from the other tracks.
If you want to monitor your recording (listen to it while you are recording
it), then on Windows or Linux: open the system volume control panel and
unmute and turn up the playback volume for your recording source e.g.
microphone. If you are on OS X, use the "hardware playthrough" option on
the Audio I/O tab instead. If this does not work, use the "Software
Playthrough" option on the same Audio I/O tab. This works on all operating
systems, though there is inevitably some delay in hearing the sound with this
playthrough method.
If you are on Windows or Linux, double-check your recording source
is set to the actual source (e.g. microphone) in Audacity's Mixer Toolbar
dropdown selector
http://audacity.sourceforge.net/onlinehelp-1.2/toolbar_mixer.htm
It's a common error when recording over other tracks to set the recording
source in the dropdown selector to "stereo mix" or comparable option
for recording what the computer is playing. You don't want to do this as
you will record a mix of the existing tracks and the one you are
recording.
Always use headphones when recording, even if you are not monitoring the
recording. If you don't, the microphone may pick up the playback of the
existing tracks in your recording.
Note that due to unavoidable latency in consumer-level computer audio setups,
there will be a delay between singing or speaking into the microphone and that
sound being laid down in the recording. Audacity will try to correct for this by
pushing the recorded track backwards slightly after recording, but you can
always adjust the synchronisation of the recorded track and the others by using
the Time Shift Tool <---> (Hotkey = F5) top left of the Audacity screen, to
drag the recorded track left or right to its correct position.
