I wonder if you could answer 3 questions, please:
    1.    I made a recording, as I have done before, but when I played it back the volume was very low. Is there a way for me to reburn it at a higher volume, or do I have to rerecord the entire thing?
    2.    I have a solid music track that I use as a background for meditations. If I want to put several meditations on 1 CD and use that same background continuously for each one, but want to separate them, is there  a way to put in a silent brake to split them? (hope that makes sense to you)?
    3.    Is there a complete manual for using Audacity that I could download?
Thank you for your time and help. I appreciate it.
