Not all masters benefit significantly from shorter sides. However, it's the bass content in the music that takes up the physical space on the disc, so it's sometimes possible to have a longer side without compromising the level or audio quality. Our general guideline for maximum side length is 20 minutes for a 12" 33 rpm record and 14 minutes for a 12" 45 rpm record. It's recommended to provide a vinyl premaster that already has low frequency level and stereo content that is suitable for vinyl production.Īs a general rule, the longer a side is, the quieter the record will be. The cutting system is equipped to correct minor issues with the bass however, more severe problems will result in a record that can't be cut or that sounds very different from the source audio files provided. Excessive stereo information in the bass appears as vertical movement in the groove, so it's sometimes necessary to remove the stereo component of the music as well as any out of phase information in the very low frequency range. It's recommended to provide a vinyl premaster that already has a balance of high frequency suitable for vinyl production.Įxcessive level in the very low bass can cause the record to skip. Since we need the record to be playable on all types of equipment, it's necessary to limit the High Frequency information. The lacquer cutting system (the next step in vinyl manufacturing) is capable of putting very high peak levels on the record, but only ideal playback systems in optimal conditions will be able to play the sound back without distortion. ![]()
