Hi Mike! You can use the Auto Duck effect to create a voice over. Make sure the voice track is below the music track and use the track align options to move the voice track to where you want it to start. Then make sure only the music track is selected, select the audio by pressing j shift-k and apply Auto Duck. If you want The music to fade to silence during the voice track cut it off where you want it to end and perform a fade before applying Auto Duck.

I'd like to add music to an already existing audio file in such a way that I can combined the music and the audio file together. Thus, when the completed file is played back, in the beginning of the recording, the music will start to play first, then after so much time, the music will fade slightly and the audio file containing me speaking will play, creating a smooth balance between my voice and the music, similar to what happens when someone is talking live over the radio with background music playing. Then, once that recording is done, I can fix it so that the music will either fade back up, or fade to silence completely, when the speaking portion of the recording is done. Thus, allowing me to create a somewhat professional sounding recording. I say somewhat professional, because I don't have any pro audio equipment or anything fancy like a studio would. Also, is there a way to get audacity to record in stereo? Thanks. Mike Rochester, NY.
