- Typical time between tracks varies from about 2-4 seconds. A DAT is sent to
- the pressing house. With the DAT you also need to send a play sheet that lists
- the absolute start time and length of each song. You need 15 seconds at the
- beginning and end of the date that is completely blank. You need no test tones
- on the tape since the transfer will be digital.
-
- You DAT will need to be "level corrected" either before you send it to the
- pressing house or after. Before is better since they charge lots of cash for
- mastering. The level correction is actually called normalization. All this
- does is make the peak of every song the same level so a person doesn't have to
- play with the volume on their stereo for each song. Also make sure you record
- at 44.1KHz vs 48KHz since sample rate conversion would have to be done or an
- analog step would be needed to get the sample rate to 44.1KHz.
-
- The pressinfg plant will charge a slight amount to convert from DAT to Sony
- 1630 format which the disk is cut from. The more you do on your end as far as
- prep goes the less you will wind up paying.
-
- I do all my mastering and mastering for other folks on a NeXT and they take the
- tape with the times and length of songs to the pressing plant they use.
-
-
- There are quite a few pressing plants. Disc Makers in Pittsburg,Pa. and
- New York have a policy of satisfaction or they refund your money.
- They als have a 1 week turn around for cassette.
