Vibration

A Mobile Lite workflow for repeatable structural-response comparisons using a known audio program, microphone identification and phone motion sensors. Absolute sensor scale, anti-aliasing and acoustic SPL are not independently validated.

What this tool does

Listen to external playback and compare recorded motion with an explicitly selected A-reference.

Inputs:

phone motion sensors
microphone
external Structure Coupling v1 WAV or Engrove Mobile Lite 6 on YouTube

Outputs:

power-domain response evidence
quality checks
same-device comparisons, not feedback margin

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.
VTA & SRA Lab: Estimate how tonearm height, mat thickness and geometry changes affect stylus rake angle and vertical tracking angle setup.
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 teaching simulation with fifteen scenarios for turntable, tonearm, cartridge, geometry, setup forces, resonance, record defects and isolation. It is not a measurement tool.
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.
Mobile Lite calibration: A guided, one-off sensor calibration for Mobile Lite tools. Four short movements measure how this phone\u2019s motion sensors are mounted; the result is stored on the phone and never leaves it.
Optical rate calibration: Reference a phone rotation sensor using repeated camera scene recurrence at 33⅓ and 45 RPM. Local profile with explicit compatibility limits.
