VTA & SRA Lab

Estimate stylus rake angle changes caused by tonearm height, mat thickness and setup adjustments.

What this tool does

Estimate stylus rake angle and vertical tracking angle changes from tonearm height, mat thickness and geometry adjustments.

Inputs:

effective tonearm length
height or mat-thickness change
stylus and cantilever geometry context

Outputs:

estimated angular change
setup direction and sensitivity context
plain-language VTA/SRA interpretation

Engrove Audio Tools

Part of Engrove Audio Tools 3.0, a browser-based turntable, tonearm and cartridge setup toolkit.

Tonearm Match Lab: Estimate cartridge-tonearm resonance frequency and check whether a cartridge, tonearm and tracking force combination falls within the practical setup range.
Compliance Estimator: Estimate a 10 Hz cartridge compliance value from manufacturer specifications so resonance calculations can use a practical low-frequency reference.
Tonearm Geometry Lab: Calculate tonearm alignment geometry for pivoted tonearms, including null points, overhang, offset angle and tracking error across the record surface.
Data Explorer: Browse active runtime cartridge and tonearm reference data for setup values used by matching, compliance and geometry workflows.
Measurement Lab: Measurement Lab is an advanced desktop workflow for browser audio input, Demo Mode, captured measurement sessions and cautious analysis; it is not a substitute for lab equipment.
Simulator: Interactive 3D turntable setup simulator for visualising deck, tonearm and cartridge setup relationships.
Turntable Level: Mobile-only setup aid that reads approximate phone tilt to help level a turntable platter; it is a practical reference, not a calibrated inclinometer.
Engrove Audio Tools — Mobile Lite: Phone-friendly Engrove Audio Tools mode for small touch screens and local phone sensors, exposing only the tools that are practical beside audio equipment.
Wow & Flutter: A mobile phone-sensor setup aid for approximate turntable platter speed and short-term variation, using motion sensors only and not claiming calibrated wow-and-flutter measurement.
