Today I want to write about affordable music equipment and where you can buy it. I will not write about expensive high end gear. Nowadays you can buy pretty high quality equipment and pay around a total of $1500 for a whole music studio (without computer). Here is a list of what you need to record music including product suggestions:
Software (DAW = Digital Audio Workstation):
To produce and record your music professionally you need to buy a music software. Here are my personal top 5.
Logic Pro X (Apple) https://www.apple.com/logic-pro/ (only for Apple Mac Computer)
Studio One (PreSonus) http://www.presonus.com/products/Studio-One

Pro Tools (Avid) http://www.avid.com/pro-tools
An audio interface is used to make good quality recordings on your computer. It is an external sound card with connections for microphones, guitars, speakers and so on. Common connection to your computer is USB or Thunderbolt (Mac).

I think this is pretty much all you need to start. Don't think expensive equipment will automatically bring you higher quality sound. Start with mid price equipment and spend more time with recording, mixing, listening, adjusting... Some people they have the best equipment but they don't know how to use it. I guess you know what I'm talking about. Let me know if you have any questions, I will try to help to find the right equipment for you.
