turn off any heavy compression or limiting on your mix buss
if possible, deliver mixes with at least 6 db of headroom, i can essentially work with whatever you send as long as it’s not clipping, but ideally the more headroom, the better.
bit rates & sampling
export your files at the same sample and bit rate as your original mix session and recordings
Use 24-Bit Depth. downsampling for cd releases can easily be applied in the mastering stage
misc.
deliver files as .wav or aiff
include detailed notes
point out concerns. If there is something in your mix you’d like to specifically address, let me know!
