All of our mastering includes free revisions of the submitted mix, a quick turnaround time (typically 3-5 days or less), and any deliverables you require. The default formats returned to you are: a 24-bit/native-sample-rate WAV for all of your high resolution needs, a 16-bit/44.1kHz WAV, and a 320kbps MP3. If you need any other formats feel free to request them and we will be happy to provide them at no additional cost. All formats undergo thorough quality checks. When mastering an EP or Album we take great care when spacing tracks and are happy to incorporate transitions or crossfades. A DDP file for a CD master, complete with all CD-Test, ISRC codes and UPC/EAN (if provided) is also included upon request.
