Audacity is free...
SC, rdelong mentioned ProTools also, but we're talking about high school kids. ProTools is not only expensive, it's complicated. Either of those would have been a deal-breaker for my program. I'm using this as a support program, and teaching ProTools would require a lot of class time.
I'm still waiting on the microphone to come in to use with Audacity at school, so I haven't had time to play with it. That's why I was asking. (WRobert--that's the only thing about Audacity that isn't free. You have to have a USB mic. I ordered
this one for about $100, but I've seen them as low as $70.)
Thanks for all your input. Hopefully I'll know more by the end of the week.
