How to Mix for Vinyl: Low End, Phyisical Limits, and What the Format Demands
Vinyl is a physical medium. The audio is cut into a groove by a needle. There are things the needle can and cannot do.
Understanding these physical limits means your mix doesn’t collide with them at the mastering and cutting stage — which is where revisions get expensive.
The stereo bass problem
The most critical vinyl mixing requirement: mono bass.
A vinyl groove encodes stereo information through the lateral (side-to-side) and vertical (up-and-down) movement of the groove. Low-frequency stereo information creates large vertical groove modulation. Too much vertical movement causes the needle to jump out of the groove during playback.
Bass content below 100Hz must be mono for vinyl. The cutting engineer will mono the low end anyway — but if your mix has been built around stereo bass content (widened bass synthesizers, stereo reverb on the kick), the mono conversion will change how the low end sounds. Better to mix it mono from the start.
Check your mix in mono below 100Hz. Does the bass still have the weight and character you intended? If it disappears in mono, the bass is stereo in the sub range and will cause problems.
Sibilance and high-frequency management
Sibilant consonants on a vocal — S, T, SH sounds — create very high-amplitude, brief bursts of high-frequency energy. On vinyl, extreme sibilance can cause distortion at the cutting stage, particularly on the inner grooves of the record where the cutting speed is slowest.
Apply de-essing more carefully for vinyl mixes than for streaming. The cutting engineer has tools to manage sibilance, but extreme sibilance will require them to either reduce high-frequency level globally (affecting everything) or cut at a lower level (reducing overall loudness).
Overall level and loud mixes
Louder cuts require deeper grooves. Deeper grooves take up more space. On an LP side with 20 minutes of music, there’s a limit to how loud the cut can be.
Don’t deliver a heavily limited, compressed-to-maximum mix for vinyl mastering. The dynamics matter both sonically and physically. A mix with 6–8dB of genuine dynamic range gives the cutting engineer flexibility to cut at an appropriate level without forcing deep grooves that limit the playback time.
The runout groove: inner groove distortion
The innermost portion of a vinyl record — the last few minutes of a side — cuts at the slowest speed. This reduces the system’s ability to accurately cut and play back high-frequency content, and increases distortion.
If you’re arranging the track order on a vinyl release, place the most frequency-demanding, loudest tracks on the outer grooves (first on each side). Less demanding material can tolerate the inner grooves better.
Phase coherence
Any significant out-of-phase content in the mix creates vertical groove movement that causes playback problems. Mono-incompatible elements in a mix — bass that cancels in mono, extreme phase-based widening — become physical problems on vinyl.
Run a thorough mono check before submitting a mix for vinyl mastering. Every element that disappears in mono represents phase cancellation that will cause physical groove issues.
What vinyl does to music
Vinyl’s physical constraints — the bandwidth, the dynamic range, the mono low end — are also partly responsible for why vinyl sounds the way it does. The format’s limitations shape the sound in ways that many listeners find pleasing: warmer, more cohesive, more musical.
