Plan sides before the final master
Vinyl preparation starts with a side plan. Decide which tracks belong on each side, where the side ends and whether the sequence supports the release. Longer sides can create practical compromises during cutting. The right decision depends on the music, intended level, programme length and the facility’s process.
Do not force an album into an unsuitable side division to preserve a digital sequence. Compare musical flow with physical constraints. A short side may allow more room for level and dynamics, while a longer side may require a different balance. Your mastering engineer should advise on the actual project.
Frequency and stereo decisions
Low-frequency energy and wide stereo information require particular attention because the cutting system translates them into a groove. Excessive or uncontrolled low end can create tracking challenges. Very wide bass information may also be unsuitable for the physical medium. These are review points, not universal prohibitions.
Ask for a vinyl-specific review rather than assuming a digital master is ready. Keep the digital release master and vinyl master clearly named. Include version, date, side and sequence in the filename and delivery note.
Dynamics and level
Level decisions are programme-dependent. A dense, loud master may need a different cutting approach from a dynamic acoustic recording. Avoid prescribing one loudness target for every record. The mastering engineer and cutting engineer should assess the music, duration and desired result together.
Provide references that describe intent. “Keep the vocal forward” is useful. “Make it louder” is incomplete without context. Confirm whether fades, gaps, side breaks and hidden tracks are intentional.
Pre-master communication
Send the facility’s accepted format and delivery instructions to the mastering engineer early. Clarify whether they need one continuous file per side, track-separated files, cue sheets or another structure. Confirm sample rate, file type, naming and metadata requirements with the selected supplier rather than using a generic template.
Document any approved changes. A final approval email should identify the exact version, side allocation and date. This avoids a later confusion between a reference mix, a digital master and the production master.
What to prepare and what to check
- Final track order and proposed side breaks.
- Notes on fades, gaps, edits and intentional noise.
- Separate, clearly named digital and vinyl masters.
- Supplier delivery specifications and contact route.
- Approval owner with authority to release the files.
Final technical requirements depend on the pressing facility and mastering engineer. Treat their current written specification as controlling. Check the approved files, not only the upload confirmation.
