Sending Us Your Files...
Technical details about how we prefer you to provide files
Tasteful compression on individual instruments is fine but don’t normalize, compress, limit or EQ your stereo mix at the output before you give it to me. The mixes should not peak over 0 dBFS and if they “look” soft on your editor after the mix-down – DON’T TURN IT UP.

You can send (and receive) your project from anywhere in the world over the internet to HDQTRZ Mastering Studios (we have a high speed line with lots of bandwidth allowing us to download your large .wav or .AIFF mix files.)
