Before cutting

Audio requirements.

Formats, lengths, levels and phase for the files that go to the cut, and how to deliver them.

AFG specification · May 2026

Formats

  • Lossless WAV, AIFF or FLAC files, at the highest resolution available, up to 32 bit / 192 kHz.
  • Other formats can be handled after a technical check.
  • One file per side, with the tracks in sequence and the gaps already set. Track markers are added during the cut.

Dynamics and frequencies

  • The recommended frequency range is 20 Hz to 20 kHz.
  • Average level should not exceed −10 dB RMS, unless there is a specific artistic reason.
  • Very energetic high frequencies, aggressive transients and sibilance can distort, particularly towards the centre of the record.
  • For heavily compressed or limited material, also send a version with more dynamics.

Stereo and phase

  • Low frequencies, roughly up to 200 Hz, must be mono-compatible.
  • For long LPs cut at a lower level, keep phase correlation within 90°.
  • For high-level 12" maxis, do not go beyond 60°.

Side lengths

  • 12" at 33⅓ rpm: 18 to 20 minutes per side.
  • 12" at 45 rpm: up to 9 minutes per side.
  • Length and cutting level are linked: a longer side needs a lower level.

Delivery

  • Name the files CATALOGUE_SIDE-A and CATALOGUE_SIDE-B, with the catalogue number in capitals, no spaces and no symbols.
  • Attach a tracklist with the title, the duration and the start timecode of every track.
  • Send a WeTransfer or Dropbox link to info@afgmediacompany.com.
  • Put the catalogue number, the label, the quantity and the title in the email subject.
  • If the master has not already been prepared for vinyl, Enisslab checks it before the cut.
