Music questions...

Hello, I have some questions about audio in unity.

  1. How can I have an audio source quickly play through it's audio clip while it is muted (I want to make a music based game where player's can use their own music, so I need to analyze the audio).

  2. If I am using something like this to get the files, is there any way I can get unity to convert music that is in mp3 and wav format to the required Ogg Vorbis format?

Thanks

for the second question i would just search google for free converters.
