Behind the Cut.
Vinyl is one of the few formats where mastering, mechanics and playback all meet in the same groove. Behind the Cut documents some of the practical engineering involved in turning finished audio into a record that not only sounds good, but physically cuts and tracks reliably.
These articles are written from the cutting bench. They are intended to help artists, labels and engineers understand what vinyl actually demands — and why the process at Diz Lathe Cuts is more thorough than simply loading a file and pressing play. Written from the cutting bench — for anyone who wants to understand what the format actually demands.
Why a Digital Master Isn't Always a Vinyl Master
Vinyl is a physical format. The groove has to physically encode the music — what sounds great digitally doesn't always cut reliably.
ArticleAudio That Can Be Difficult to Cut to Vinyl
Sub bass, sibilance, hard percussion, excessive limiting, phase problems — a practical guide to programme material that creates challenges at the lathe.
ArticleWhat Happens If My Master Won't Cut Reliably?
How Diz Lathe Cuts handles audio that cannot be cut or tracked reliably as supplied — what gets tested, flagged, and when revised files may be needed.
ArticleWhy Vinyl Cutting at Diz Lathe Cuts Takes Time
Cutting a record is not pressing play and letting the lathe run. The preparation, testing and verification involved in every session.
ArticleHow to Supply Audio for the Best Vinyl Cut
Format, bit depth, sequencing, what to avoid — and why making your digital master 6dB quieter is not the same as a vinyl master.
ArticleWhat Does Vinyl Preparation Actually Mean?
The difference between standard cutting setup (included with every order) and vinyl preparation (technical vinyl preparation for source material that needs it).
Article 7The Cut Comes Last
Why file assessment comes before anything goes to the lathe — on cut level, loudness, side length and why short professional runs are what lathe cutting is for.
Article 8Bass-Heavy Music and Vinyl
What happens to electronic bass in the groove, and how to prepare a dance music master for vinyl cutting.
Article 9When the Lathe Stops
On swarf, blank quality, heat, humidity and programme behaviour — and why there are no guaranteed delivery dates.
Article 10Why Quality Is Everything
The blanks, the custom-built tools, the audiophile background, and why the best results always start with the right master.
Article 11How Vinyl Records Are Cut
Running time, RPM, bass, loudness, stereo width, groove spacing and inner-groove behaviour — what a cutting engineer actually does.
Article 12Reading Music as Groove Geometry
Excursion, width and velocity: the three mechanical dimensions of a record groove, and why digital loudness measurements cannot tell the whole story.
