Vinyl as any other format has its own limitations. To make sure your music sounds great on a record, please comply with general mastering for vinyl standards:

  • Peak Level: < 0db
  • Low frequency cut at 10hz
  • Low frequencies below 250hz in mono
  • Be careful with extreme peaking above 16khz
  • No negative phase returns
  • Stereo width between  +0.5 and 1
  • File formatting:  .wav / .aif
  • Audio quality: 24bit; 44.1- 48Khz

Remember to master your music. Mastering for vinyl is essential to ensure the best quality of the record.


Loudness and frequency spectrum have a direct effect on playback times on a vinyl record. Extended playback times may results in the loss of low end, low volumes and poor quality. For the best quality results please keep your record sides up to 20 minutes.


  • 12″ 33 RPM – up to 22 minutes per side.
  • 12″ 45 RPM – up to 15 minutes per side.

33 or 45 RPM? – RPM is an abbreviation for “revolutions/rounds per minute”. This refers to the playback speed and directly affects length of a record. Please consult your mastering / cutting engineer for choosing the speed that is most suitable for your program material.

Mastering is essential for the vinyl format in order to avoid distortion, mechanical playback issues and generally to make the record sound as good as possible. If your music is not mastered, mastered for digital formats or if you need re-mastering, we highly recommend ordering professional mastering services with us.

  • Mastering from a variety of formats: CD, tape, DAT or digital files.
  • Converting a digital master to a vinyl pre-master.
  • Analog / digital in-depth mastering with high-end equipment.

If you are not quite sure about the mixing and mastering quality, we recommend ordering one copy reference cut on acetate.

Reference cut is an excellent and inexpensive way to learn about how your program material will translate to the vinyl format.

Up to 20:00min – 790DKK / 110EUR
