I use Reaper software. It's free to try, so I never bought it, I use the free version. Buying is only like $60, though. I did use Audacity before, but now I learned to use Reaper so don't use Audacity anymore. Opening a band practice mp3 of 250MB takes like 15 minutes on Audacity, and 10s on Reaper.
And I Have Zoom H4 that I use as the mic or preamp or whatever, that plugs via USB cable to my laptop.
