FREQUENTLY ASKED QUESTIONS

How should I submit my files for audio mastering?

Please submit files for audio mastering in their native recording resolution at the highest possible bit depth. We accept file resolution up to 32 bit/192KHz, WAV or AIFF. If you’re submitting analog tape, please call us to arrange shipment and discuss the session requirements.

What are ISRC codes and how do I get them?  

ISRC, or International Standard Recording Codes, are 12-digit unique identifiers for your recordings. They allow an artist or label to track sales, airplay and royalties. ISRC codes are required by most digital distribution companies and music purchasing sites in order to sell your music online. This is different from a UPC code, which is used to track physical merchandise like CD’s and vinyl.

Apply for ISRC codes and learn more about them at www.usisrc.org

What are Apple Digital Masters (MFiTs) and are they necessary for iTunes distribution?

Apple Digital Masters, or Mastered for iTunes Files (MFiTs), adhere to a set of guidelines created by Apple to accurately deliver an artist’s music on iTunes. Files that are not Apple Digital Masters are still eligible for iTunes distribution. If you’d like to receive Apple Digital Masters, confirm that your distributor allows this format. 

What is a DDP and why do I need one?

A DDP, Disc Description Protocol, is a format used for CD replication. This file allows us to embed CD text, ISRC codes and UPC codes. If you plan on manufacturing CD’s, check with your distributor, or manufacturing plant, to verify DDP submission is possible.

Can I attend my session?

You can attend your audio mastering session for an additional charge, or schedule a tour of the studio before your project starts. Unfortunately we don’t offer attended sessions for vinyl mastering.
