Mixing is the process of taking all the seperate stems within a song and mixing them together, using processes like eq, delay, reverb, compression, saturation etc and setting perfect levels a until it feels like a professional and complete song. i use analog and digital tools when i mix and master, and some of my analog equipment includes zahl eq1, grandchild compressor, tk tklizer eq, spl vitalizer tube, elysia compressors and more.
