The basic specifications to keep in mind (wikipedia):

  • Maximum playing time is 79.8 minutes
  • Minimum duration for a track is 4 seconds (including 2-second pause)
  • Maximum number of tracks is 99
  • Maximum number of index points (subdivisions of a track) is 99 with no maximum time limit
  • International Standard Recording Code (ISRC) should be included

Sample Rate

The final sample rate should be 44.1kHZ (44,100HZ)

Bit Depth

The final bit depth should be 16-bit

The 2 Second Pre-Gap

Due to physical limitations, a 2 second pre-gap, or pause, is required before the first track on the disc. When creating a DDP or burning a disc, it will be added by Triumph automatically, so Track 1 of your project should, generally, start at 0:00:000.


This serves to improve the apparent signal to noise ratio, by filtering out some the high frequency noise on playback. On playback, the player applies a low-pass filter to restore the frequency response curve to an overall linear one. Playback of such discs in a computer typically does not take into account the pre-emphasis, so such files play back with a distorted frequency response. (wikipedia)

Serial Copy Management System (SCMS)

While not formally part of the specification, you may choose to use it for your discs.

SCMS sets a "copy" bit in all copies, which prevents anyone from making further copies of those first copies. It does not, however, limit the number of first-generation copies made from a master. (wikipedia)

There are three states of these bits: copy allowed (00), copy once (10) and copy prohibited (11). If the source has the copy bits 00, and a copy is made of the source, the copy itself will have the bit set as 00 as well, allowing copies to be made from copies. If the source has the copy bits set as 10, every copy of this material will have the bits set to 11, and making a copy from the copy would be prohibited. (wikipedia)
