SimuLathe REF

Tokyo Dawn Labs

Where to get itAvailable from Tokyo Dawn Labstokyodawn.net

SimuLathe REF is a virtual disc-cutting lathe plugin that accurately models the complete vinyl mastering process, from audio input through groove cutting and virtual playback. It provides mastering engineers and producers with a parametric model of cutting lathe mechanics, generating precise 3D groove representations that can be analyzed with virtual pickups and monitoring tools. Tailored for engineers without access to real cutting systems, REF enables educated decision-making on material suitability for vinyl while revealing the acoustic trade-offs inherent to the disc format.

Written from the manual and checked against it. How we check

Key Features

01Parametric cutting lathe model with groove geometry prediction and space consumption calculation
02Virtual groove microscope with detailed 3D visualization and manual measurement tools
03Disc surface statistics window with heat maps (excursion, width, velocity, land width)
04Three pickup simulation models: HiFi (MicroRidge), MidFi (average elliptical), and Club (DJ elliptical)
05High-pass, elliptical and low-pass preprocessor filters with adjustable slopes
06Dual pitch modes: Variable Pitch (modern) and Fixed Pitch (vintage)
07Groove width options: Normal and Deep
08Playback defects simulation including disc wear, tracking angle, crackle, clicks, and system noise
09Real-time lathe metering: Pitch, Groove Width, Velocity, Temperature, Head Current, THD, SNR, PPM Cut, VU Cut
10Host sync (perfect DAW timeline integration) and Manual sync modes
11Support for up to eight disc sides (A–H) with track marker placement
12RIAA decoder bypass for monitoring raw cutting signal paths
13Circuit breaker safety warnings based on temperature and current limits

Things to Try

  • 01Use Manual mode to hear how the sound at the beginning of a record compares to the sound at its end, helping decide which song to put last on a side and where to end the side
  • 02Set Disc Wear to 10% in the Playback Defects panel to add realistic test-pressing aging characteristics
  • 03Monitor the Velocity meter and keep high velocity regions as short as possible; very short signals up to 60–70 cm/sec are typical for hot cuts depending on cutting amp and cutter head condition
  • 04Use the RIAA Decoder Placement option to monitor the signal as seen by the pitch computer, or Velocity option to see the signal as it hits the cutting stylus
