My Question is,    Is there a way to get the Audio input from a line in playing an Ipod or live music. It works fine with the built in Microphone but not with my Ipod.     I've changed the settings on my mac to the line-in. 

I've seen that the minim sound library can do it with the getLineIn function but was wondering if anyone has any experience with the Krister.ess library.(see below)

Any help would be greatly appreciated. 

thank you.
