I use Windows Vista Business on my laptop and I downloaded audacity 2.x how ever when i try to make a backing track from mp3 files the wave patterns are missing… all i have is just a line…
Also when i tried recording my voice for a Japanese project… the wave patterns were there for a milisecond then it became a straight line
If you Import an audio file (File menu > Import > Audio)
then you should see the waveform appear.
Are you sure that the audio file really is an MP3 file?
Does the MP3 file play correctly in your media player?
