I am not an expert, but I just looked at Audacity and it does allow for a microphone for input. I’ve used it to record broadcasts off the internet, but I haven’t used the microphone for input.
Recorded input is saved to a file that you specify. I’m not familiar with Finale, so I’m not sure which file type is best for you. I would guess MP3 is acceptable.
I’d suggest that you download it and play around with it for a couple of hours. There is a small learning curve to get over.
Someone suggested TotalRecorder. I just bought the Professional version of this. It isn’t any easier than Audacity to use, but Total Recorder allows me to make scheduled recordings of internet radio, on the fly. But for your purpose, Audacity is equally good.
I’ve been playing with Audacity and it looks like it’ll do the job, so thanks a million!
A couple questions -
1) On the pull down window where it lists microphone, phone line, in line, etc. - what does “in line” mean?
2) How do I separate each piece of music into it’s own track?
