DDP (Disc Description Protocol) is the current way many replication facilities request you send your CD to master. You can upload the file rather than to send a physical CD.
Apple has strict requirements to include your release on iTunes. They recommend 24bit masters. We can provide iTunes compliant masters. No need to worry.
Depending on where you plan to distribute your release, the requirements may be different. Let us know where you plan to release it and we'll provide the highest quality files they allow.
We can master a single or an entire album. Our specialty is in bringing a mix to a higher level rather than the traditional approach of minimal adjustments. Your release will win any "Volume War" and will sound stellar.
