How to Mix for Vinyl
Vinyl is a physical format with real physical constraints — the cutting lathe, the groove, and the stylus all impose hard limits on what your audio can contain. Excessive stereo width causes the stylus to jump, deep bass in stereo makes grooves unplayable, and harsh sibilance can distort on playback. Mastering for vinyl requires understanding these mechanical realities and preparing a master that respects the medium while preserving the musical intent.

How to Optimize Your Mix
Sum Bass to Mono Below 150 Hz
Stereo information below 150 Hz causes the cutting needle to move laterally in ways that make the groove unplayable. Use a mid/side EQ or a stereo imaging plugin to mono everything below 150 Hz. This is non-negotiable for vinyl.
Reduce Overall Stereo Width
Extreme stereo width creates wide groove modulations that are difficult for styli to track. Pull back stereo widening effects, reduce hard-panned elements, and ensure the side (stereo difference) signal does not exceed the mid signal in level.
De-Ess Aggressively
Sibilant frequencies (5-10 kHz) create sharp, high-velocity groove excursions that cause audible distortion on playback — especially in inner grooves. Apply more aggressive de-essing than you would for digital. A 6-8 dB reduction on harsh sibilants is typical.
Mind the Inner Groove Distortion
Vinyl playback quality degrades toward the center of the record because groove velocity decreases. Place your most dynamic, high-frequency-rich tracks at the start of each side (outer grooves) and quieter, simpler tracks toward the end.
Preserve Dynamic Range
Vinyl thrives on dynamics. Heavily limited, brickwalled masters sound worse on vinyl than on digital — the medium itself adds saturation and compression, so feeding it an already compressed signal creates a messy, congested sound. Target -14 to -16 LUFS.
Manage Overall Level for Side Length
Louder cuts require wider grooves, which reduces available playing time. A 22-minute side at 33 RPM needs to be cut quieter than a 12-minute side. Discuss target levels with your cutting engineer based on your program length.
Common Mistakes
Sending the Same Digital Master
A master optimized for streaming (loud, limited, wide stereo) is the worst thing you can send to a vinyl cutting engineer. Vinyl needs a dedicated master with mono bass, controlled width, and more dynamic range. Always request or create a separate vinyl master.
Excessive Sub-Bass in Stereo
Stereo bass content below 150 Hz causes the cutting needle to cut grooves so wide that the playback stylus cannot track them. The result is skipping, distortion, or a cutting engineer having to drastically EQ your master.
Ignoring Track Order
Putting your loudest, most energetic track last on a side means it plays in the inner grooves where quality is worst. Sequence sides so that the most demanding tracks play first (outer grooves) and simpler material plays last.
Over-Loud Masters for Long Sides
Requesting a loud, punchy cut on a 23-minute side is physically impossible. The cutting engineer will either compress your audio, cut the level dramatically, or refuse the job. Keep sides under 20 minutes for optimal quality.
Frequently Asked Questions
The vinyl cutting process uses a stylus that cuts grooves representing the left and right channels as vertical and lateral motion. Stereo low-frequency content creates wide lateral movements that make the groove physically unplayable — the playback stylus skips or mistracks. Summing bass to mono below 150 Hz keeps these movements controlled.
It depends on the side length. Shorter sides (under 15 minutes at 33 RPM) can be cut louder, while longer sides (20+ minutes) need to be quieter to fit the grooves. A typical vinyl master is -14 to -16 LUFS. Discuss target levels with your cutting engineer.
Most cutting engineers prefer 24-bit WAV files at 44.1 kHz or 96 kHz, with individual tracks as separate files in the correct sequence. Some accept DDP files. Always ask your specific cutting facility for their preferences before sending files.
45 RPM provides better audio quality because the groove velocity is higher, especially in the inner grooves. However, it limits side length to about 12-15 minutes. For singles, EPs, or audiophile releases, 45 RPM is the premium choice. For full-length albums, 33 RPM is standard.
