I have used Audacity for many a recording. Best results were accomplished sending the signal through a preamp to a delay and then an interface to the PC. I used an ART Tube MP as the preamp and didn't use any of the built in effects in Audacity.
BandLab is what I’ve been using with just cell phone and my harp can’t use my mic or amp with it I can’t afford an interface would be a much better product if I could lol ??
