I want to make mastering of piano music. These will be piano pieces. Each will last from two to three minutes. I will combine these pieces into the album. The album will have from eight to ten pieces. The finished recording will only have a piano - one instrument. After mastering I will upload the finished recordings to different music sites - this will be the only way to distribute these recordings. There will no be physical media - CD, DVD - in distribution.
What steps I need to make and what equipment to use to make mastering of piano music?
