[chuck-users] minimizing load time for tons of audio

[Robert Poor]

Michael:

If you're on a Mac, and If you're comfortable with simple command line  
programming, have you considered using the "afplay" command?  It's as  
about as low level as it gets:

Multiple calls separated by semicolons will play sequentially (i.e.  
'afplay song1.mp3 ; afplay song2.mp3').  Invoking afplay in the  
background will mix (i.e. 'afplay song1.mp3 & ; afplay song2.mp3 &').

Maybe that's all you need?
