You’ll receive the normal WAVE master for all stores except iTunes and a WAVE file for iTunes, your label’s music distributor or your music distributor must upload these files correctly. We send a 24 bit master for better quality but all stores except iTunes require 16 bit files (almost every store will convert your 24 bit master to 16 bit automatically, if you need a particular bitrate or bit depth, just ask) For iTunes (Apple Digital Masters) the WAVE file is 24 bit.
