Mastering is billed per track, with cost added depending on options, for example: optimized .wav files for vinyl, MFiT (Mastered For iTunes), and alternative mix masters (such as an instrumental version), to name a few variants.
The standard base rate is typically $65.00 per track before add-ons.
This base rate (at the artist's request) can include, but is not limited to the following file formats: .wav files, mp3 files, aac files, and a DDP in the case of CD pressing. One (1) free revision per track is also included in the base rate.
