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.
Handling masters
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. |
