Mixing
Muddy sound? Too much low end? Vocals not sitting right in the mix? Drums and bass fighting for space? We've got your back.
We can mix from stems or individual tracks, and get everything just right.
Have reference tracks you'd like to 'mix match' to?
We can do that with ease! See our portfolio for examples of mixing that we have undertaken.
Our Mixing FAQ is here

Mastering
So, you're happy with your mix, it all sounds as it should. But it's missing something.
Does it sound a little thin? Lifeless? Does it need some sparkle, more width, less width or just be louder?
We have been there, done that. Let us help. See our portfolio for examples of mastering that we have undertaken.

Drum programming
You've been using drum samples or loops, and you aren't happy with them. Things aren't grooving!
Or maybe you want some drum tracks that would be beyond a human drummer. Or fills that are just right.
We can help - drum programming is more art than science!
See an example in our portfolio of drum programming done by us .

We agree one track to be mixed/mastered, and X3 will work on it.
We'll get it to your required quality, which may require a number of revisions.
If, in the unlikely event we can't agree on the end result, you can walk away. No ifs, no buts.
But we have confidence in our ability to deliver!
