The Art of Analog Mastering
Unlike digital mastering, vinyl is a physical medium with real constraints. Bass frequencies must be centered (mono) below 150Hz to prevent the cutting stylus from jumping out of the groove. Loudness must be carefully managed — louder cuts require wider grooves, reducing total runtime per side.
Track sequencing matters enormously on vinyl. The outer grooves have the best fidelity, so your most complex and dynamic tracks should open each side. Sibilance is exaggerated on vinyl, requiring more aggressive de-essing than digital masters. High frequencies above 15kHz need gentle roll-off to prevent harshness.
At LB-Mastering Studios, we've mastered these nuances over 44+ years. We deliver 24-bit WAV files labeled by side, ready for the cutting lathe — and we can recommend trusted pressing plants who will receive files in exactly the format they need.

Runtime & Loudness Trade-off
Longer sides require quieter cuts with less bass. Pushing runtime limits compromises audio quality. Staying within optimal limits ensures the best sound — and gives the cutting engineer room to work with your dynamics.
Vinyl-Specific Requirements
These are the critical technical differences that separate a great vinyl master from one that skips, sounds harsh, or loses fidelity.
Mono Bass Below 150Hz
Wide stereo bass causes the cutting stylus to jump. All frequencies below 150Hz must be centered (mono) to ensure groove stability and prevent skipping.
Quieter Loudness Target
Vinyl masters target -12 to -14 LUFS — significantly quieter than digital. Louder cuts require wider grooves, reducing runtime and risking groove instability.
Aggressive De-essing
Sibilance (harsh "S" and "T" sounds) is exaggerated on vinyl. We apply more aggressive de-essing than digital masters to prevent harshness on playback.
Preserved Dynamic Range
Vinyl sounds best with natural dynamics. We avoid brick-wall limiting and leave at least 3-6dB of headroom for the cutting engineer to work with.
Track Sequencing
Outer grooves have the best fidelity. Your most complex, dynamic tracks open each side. Quieter, simpler songs go toward the end where inner groove distortion is greatest.
High-Frequency Roll-off
Frequencies above 15kHz are gently rolled off to prevent harshness without losing clarity. This is one of the most important differences from digital mastering.
Industry-Standard Software
We use the world's best digital audio workstations for vinyl mastering, providing advanced features for precise audio editing and vinyl-specific processing.

Curated Plugin Suite
Our carefully selected plugins handle the unique demands of vinyl mastering — from precise EQ and dynamic control to de-essing and stereo imaging.
Vinyl-Optimized Signal Chain
Each plugin in our vinyl mastering chain is chosen for its ability to handle the specific demands of the medium — transparent EQ for frequency shaping, musical compression that preserves dynamics, and precise de-essing that tames sibilance without dulling the sound. The result is a master that translates beautifully from the cutting lathe to your turntable.
Our Vinyl Mastering Process
A meticulous, step-by-step workflow that guarantees your vinyl master is ready for the cutting lathe and sounds incredible on any turntable.
File Submission
Upload your final stereo mix in 24-bit WAV or AIFF format. Label files by side (A1, B1, etc.) and include a track listing with timings and any special instructions.
Critical Listening
Luis performs meticulous listening sessions on calibrated studio monitors, identifying phase issues, sibilance, and bass problems that would cause groove instability on vinyl.
Vinyl-Specific Processing
We apply mono bass below 150Hz, aggressive de-essing, gentle high-frequency roll-off above 15kHz, and careful dynamic control — all tailored specifically for the vinyl medium.
Analog Enhancement
High-end analog outboard gear adds warmth, depth, and character that enhances the vinyl listening experience — giving your record that sought-after analog richness.
Quality Control
Detailed QC checks verify mono compatibility, phase correlation, loudness targets (-12 to -14 LUFS), runtime per side, and that no technical issues will cause pressing problems.
Master Delivery
You receive 24-bit WAV files labeled by side, ready for the cutting lathe. We can also recommend trusted pressing plants and provide files in their exact required format.
All Genres, One Studio
Luis Berrios adapts his vinyl mastering techniques to the nuances of each genre — ensuring your record retains its unique character and sonic integrity.
Common Questions
Quick answers about our vinyl mastering services
What is the difference between digital and vinyl mastering?
Vinyl mastering requires specific adjustments: bass must be mono below 150Hz, loudness targets are quieter (-12 to -14 LUFS), dynamic range must be preserved, high frequencies are gently rolled off above 15kHz, and track order is critical for groove quality.
Why does bass need to be mono for vinyl?
Wide stereo bass causes the cutting stylus to move laterally too much, which can make the needle skip during playback. Frequencies below 150Hz must be centered (mono) to ensure groove stability.
Should I create a separate master for vinyl?
Yes — we highly recommend a dedicated vinyl master. Digital masters are often louder and more compressed, which does not translate well to vinyl. A vinyl master should be quieter, more dynamic, with mono bass and gentler high frequencies.
Do you handle the vinyl pressing or just mastering?
We specialize in vinyl mastering — preparing your audio for the cutting lathe. We do not handle pressing, but we can recommend trusted pressing plants and provide files in the exact format they require.
