master bus
Exclude all processing such as imagers, saturators, compressors, EQs, clippersor limiters from your master bus. We can discuss leaving some of the mentioned processing.
headroom
Just make sure that your mixdown is not clipping. Anywhere between -8 dB Peakand -1 dB Peak is good.
sample rate
Keep the same sample rate used inyour project. No need for upsampling or downsampling.
format
The standard formats I work with are 32or 24 Bit WAVs or AIFFs. If for any reasonyou are stuck with lower resolution formatssuch as 16 Bit WAVs / AIFFs or even mp3splease don't change their bit rates andsend what you got.
titles
Please include both artist and song names in your premaster titles.
