A Special Format

Compact Discs store music in a digital format, which means there is no need to consider or compensate for the actual recording medium when mastering. The noughts and ones you send to the CD pressing plant will be exactly the same on the finished discs. With vinyl mastering on the other hand, we need to consider the fact that the frequencies, phase & volume of each recording will have an effect on the physical master. The biggest limitations of vinyl is the fact that bass frequencies and volume greatly influence the available playback time on the disc.

Tips For Mixing

There are physical limits to what the head of a lathe can produce when cutting vinyl. Following are some general tips for mixes destined for vinyl;

  1. Have the kick and bass centered in the mix. (not panned left and right).
  2. Also avoid stereo panning any other ‘bass heavy’ instruments. Think bass, think mono.
  3. Try to eliminate as much sibilance as possible on the vocal track (de-essing)
  4. Avoid excessive amounts of sub bass frequencies (below 40Hz), as well as excessive top end (above 16kHz).
  5. Avoid excessive buss compression & limiting.

When mastering for vinyl, the rule of thumb is, ‘time versus recorded level’. That is, the louder it is & the more bass it has, the shorter the playing time. Listed below are optimum side lengths for achieving maximum bass response, volume & fidelity.

12 inch single 33 rpm: 10-12 mins
12 inch L.P. 33rpm: 15-18 mins

12 inch single 45 rpm: 6-8 mins
12 inch L.P. 45 rpm: 12-15 mins

7 inch 45 rpm single: 3 mins
7 inch 33 rpm single: 5 mins

The times below are not exactly optimum for fidelity, but still yield good results.
Discs with longer than normal side lengths are required to be cut with less volume and with possible bass attenuation.

12 inch single 33 rpm: 12-14mins
12 inch LP 33 rpm: 20-24 mins

12 inch single 45 rpm: 8-10 mins
12 inch LP 45 rpm: 15-16 mins

7 inch single 45 rpm: 5 mins
7 inch single 33 rpm: 7 mins
