CONE EXCURSION TRACE REAL-TIME

A POCKET CAR-AUDIO LABORATORY FOR ANDROID.

Most mobile audio apps generate harsh, aliased waveforms, crash under continuous low-frequency load, and fake decibel readings on uncalibrated phone mics. Subterfuge is a dedicated physical transducer workbench and DSP engine built by Ben Haker in Ontario, Canada.

The Engineering Breakdown

Subterfuge replaces fragmented calculators, inaccurate tone generators, and unstable spreadsheets with verified acoustics mathematics and sample-accurate audio worklets.

01

PolyBLEP Anti-Aliasing DSP

Standard oscillators generate infinite harmonics that fold across the Nyquist barrier as harsh digital distortion. Subterfuge applies second-order polynomial band-limited residual correction, guaranteeing zero-jitter continuous phase down to 10.0 Hz.

✓ 10 Hz – 20 kHz Continuous Sweep
02

Thiele-Small 4th-Order Mechanics

Vented enclosures act as coupled dual-mass resonators. Subterfuge computes non-linear cone displacement, modeling the critical excursion notch at box tuning frequency (Fb) and voice coil thermal resistance rise (+0.393% / °C).

✓ Dynamic Thermal Compression Model
03

16,384-Point Radix-2 FFT

Ultra-narrow 2.9 Hz bin resolution running at 60 FPS on the Android GPU. Accurately pinpoint structural cabin rattles, standing waves, and port turbulence harmonics without spectral smear.

✓ GPU Spectrogram Waterfall
04

SUBTERFORGE Box Acoustics

Parametric 3D enclosure designer. Computes gross and net volume, slot-port length, boundary gain loading, and Mach airflow warnings (<0.15 Mach) before cutting expensive Baltic Birch plywood.

✓ Automatic Wood Cut-Sheet Generator
05

Measurement Honesty

Every number displayed carries its exact provenance: Tier 0 predictive model, Tier 1 uncalibrated phone mic, Tier 2 field-calibrated meter, or Tier 3 lab-calibrated USB microphone (such as miniDSP UMIK-1 with individual cal files).

✓ 4-Tier Provenance Verification
06

Android Native Worklet Engine

Built for Android 14+ via Capacitor 8. Audio synthesis executes on an isolated real-time thread backed by zero-copy seqlock memory buses, with an instantaneous background panic mute guard.

✓ 100% Offline Runtime
