Can I use this software to record from vinyl to my Mac using 10.4?
Thanks for ANY reply...desperately seeking software for a simpleton!

Stop Complaining

Okay fair enough the program must be frustrating if it keeps crashing all of the time but instead of everyone continuosly whining , Try report this issue to the developer and they might be able to start working on a solution. The address for this is written in the description but for all the other dumb people here it is:

good, but crashes

This is a great basic recording program that does just what I need it too. Unfortunatly it crashes frequently (more than once an hour). I'd still reccomend it--just make sure you save often.

cant do anything.

Audacity will open, and run, but when I hit play or record nothing happens, the hlep file is prety unhelpful. Any suggestions?



Running Jaguar with en emac: I get "error 13 permission denied" the directory seems messed up. any help?


the software crashes continuosly. does it happen to someone else?

Re: crash

i cant do anything, has an error as soon as i hit record
