There is a program called "Studio..." I have studio IV and there is a Studio 7 or perhaps higher now. Available at WalMart, Office Depots that have not closed yet, Circuit City...most software/hardware retailers. I'm not familiar with current cost, but that is an easy google or phone call. It will record multiple tracks and allow you to cut, paste, edit, etc. each track and even adjust the sine waves if you choose, so it allows some "engineering" of the music. I play Native American flutes, and it works for me. The main thing is having good microphones well spread and a quite, sound "dead"place to record in that is without background noises like air blowing through a register or the sound of the HVAC fan or refrigerator, car tire noise on a nearby street or road, computer fan noise, pets in cages or outside, or even a clicking clock. This can be achieved more easily if you live in the country away from major roads and airplane flyways as I do. In othe locations, one can make a small recording booth just big enought to sit in with your music instrument(s), mics, and a quiet on-off switch to control the recording equipment outside the booth. It can be made of concrete blocks with plywood "roof" baffled with brick above and totally lined with sound absorbing/disbursing wall and ceiling covering such as the foam mattress liners that are smooth on one side and look like an egg carton on the other...with low velocity supply air duct well away from the unit with a box made like the room above the supply air register that kills the sound of the unit that will travel down the duct...and a fairly long and large flex duct lead into the box with some SSS curves built in to deflect and absorb reflected sound in the duct.
