Dj mix master
Ok, so you made a dj mix but in places there is more bass as a record just sounded that way, in another area an old record sounds a bit too overpowering on the top end. All records are different, so when you mix them together the sound can change a lot.
This service is to run your mix through a chain of processing to make things more even. The best results in terms of improvement are when the sources are from vinyl, where there will be a greater difference between each record.
