Physical Audio MastersIt’s important that your master sounds exactly the way you want it to sound, with all of the songs in the correct order and the right amount of spacing between songs. You should make a safety copy of your master before you ship or deliver it anywhere.
Your master must be mixed to two tracks, edited, and sequenced. Make sure it sounds exactly like you want it to sound, with all the songs in the correct order and the right amount of spacing between songs.
We do not provide equalization or level adjustments unless requested. As part of our mission to make you sound great, an engineer from The SoundLAB at Disc Makers will – upon request – preview your master FREE and let you know if your master would benefit from post production.
If you have ordered mastering from the SoundLab at Disc Makers, please download and fill out the SoundLab Engineering questionnaire, to help our engineers get the most out of your master.
NEW! DDP Saves You Time and Money
Instead of mailing in your audio master, upload a Disc Description Protocol (DDP) file. DDPs offer the same audio fidelity as a disc, but you don't have to make a trip to the post office, you don't have to spend money mailing us your master, and you save time as uploading is a bajillion times faster than mailing. Simply choose the "Audio CD" option when uploading your content; Our step-by-step software will help you do the rest.
Track listing formYou must download and complete a Track Listing Form to include with your master. Required information on the form includes a complete and accurate running time log listing all events (tones, silences, songs, outtakes, noises, etc.) as they occur.
The maximum length for CDs is 79:45 minutes. For programs over the industry recommended 78:00 total time, you must submit a signed disclaimer form with your order.
Master formats we accept
We can accept your master on one of the following formats:
• CD-R master (16-bit/ 44.1kHz CDA format only) *
• Digital Audio Tape (DAT)
• Mini Disk
• DDP 2.0
• 1/2" or 1/4" Analog Tape
* DAT, analog tape, and Mini Disk masters will need additional work performed by the SoundLab in order to prepare a replication ready master.
Additional technical information:
Digital Audio Tape (DAT)
• Digital Audio Tape: 44.1 kHz or 48 kHz sampling rate
• Pre-roll: 10-15 seconds recorded silence. (Optional) Calibration tone: 1 kHz at -12 dB (never at 0 dB).
• Start IDs: sequentially numbered, placed at the start of each selection, one number per song.
• A sampling rate of 44.1 kHz is highly recommended.
• Your dB meters should peak no higher than 0, with no over levels, and must average above -15 dB (Red Book minimum standard).
• Be sure your DAT and box are labeled.
1/2" or 1/4" Analog Tape
• 30 ips, 15 ips, or 7 1/2 ips.
• Alignment (test) tones at head: 1 kHz, 10 kHz, and 100 kHz at 0 dB operating level.
• Indicate type of noise reduction, if any, and include proper tones.
• Leader tape at head and tail of tape (15 seconds minimum) and two to four seconds in between songs.
• Tape slow-wound, tails out, in properly labeled box.
Handle all masters carefully, both before and after recording. Touch CD masters only by the edges and keep them free of fingerprints and scratches that can cause data errors. Make sure your master and box are labeled clearly with your contact information.
Film & Video MastersDVD Masters
Before sending in your master, test it thoroughly to make sure that it performs exactly the way you want it to. Your finished discs will be an identical copy of your master.
DVD+R or DVD-R are acceptable for replication of DVD-5 and DVD-10 discs, and can be produced on either an authoring or general drive. For DVD-9, you must supply two DLT masters (layer 0 and layer 1) or DDPs on DVD-Rs. DVD+R DL can also be used for DVD-9s. DLTs and DDPs on disc are also acceptable for DVD-5 and DVD-10. Any project requiring CSS or Macrovision copy protection must be authored as such and must be submitted on DLT or DDP on disc. All DLT masters must include DDP files.
Always use high-quality recordable (DVD-R or DVD+R) non-rewritable discs for your DVD masters. DVD-ReWritable (DVD-RW) discs should not be used for making DVD masters. Not all DVD readers can read DVD-RW discs. This can lead to problems during replication.

Masters for Blu-ray replication must be submitted in Cutting Master Format (BDCMF or Sony CMF) on removable USB 2.0 hard drives formatted for Windows OR files should be submitted in Cutting Master Format (BDCMF or Sony CMF) image on BD-R: Playable BD-Rs are not acceptable for Blu-ray replication. BDMV folders submitted on BD-R (playable BD-R) can be converted to a BDCMF replication ready master for a $150 premastering fee.
