A teacher friend forwarded to me a request from one of her students who wanted information on how to do home recording with her Windows PC (the teacher is a Mac user). Here’s what I replied FYI:
It sounds like you already have [free software for Windows/Mac/Linux] Audacity, which was what I would recommend for basic Windows recording. There actually isn’t a GarageBand for PC, despite what searching would have you think – the link that came up is not a product by Apple, but something downloadable from “Rare Software” – I can find no references for that from reliable sites, so personally I would hesitate to install it.
The other important part of making a decent-sounding home recording into a PC (or Mac) is how you get the analog sound (the waves of sound your harp makes through the air) converted to digital 1s and 0s inside your computer. Your PC may have a line in/mic in 1/8″ jack, or a built-in mic, but those are only sufficient for talking on Skype calls, etc. You want some type of external analog/digital (A/D) converter.
