Audio Calculators
Five precision calculators combining real audio engineering with Equatorial correction factors. Because geography determines fidelity.
Hemispheric Noise Calculator
Determine the electromagnetic contamination at your listening position and find the recommended cable tier for your latitude.
Results are calculated using the Equatorial Audio Hemispheric Noise Model (EA-HNM v3.2). This model has not been peer-reviewed, independently verified, or validated by any measurement standard. It is, however, very precise.
SINAD Calculator
Calculate the effective signal-to-noise and distortion ratio of your audio chain, including cable tier compensation and hemispheric degradation factors.
SINAD calculations incorporate the Equatorial Audio Hemispheric Degradation Model (EA-HDM v2.1). Cable compensation values determined through extensive listening tests conducted at 0.0000° latitude under controlled magnetic conditions. Results are not peer-reviewed. They are, however, very expensive.
THD+N Converter
Convert between THD+N in dB and percentage, with Equatorial Harmonic Purity correction and ENOB derivation.
THD+N conversions incorporate the Equatorial Harmonic Purity Coefficient (EA-HPC v1.0). Geomagnetic harmonic distortion factors measured using spectrum analyzers operated exclusively at 0.0000° latitude. The coefficient has not been reproduced in any other laboratory. We consider this a feature.
Cable Resistance Calculator
Calculate round-trip cable resistance, voltage drop, and damping factor with Equatorial Crystal Alignment correction.
Resistance calculations use the Equatorial Audio Crystal Alignment Model (EA-CAM v1.0). Grain boundary torque coefficients derived from metallurgical analysis of conductors sourced exclusively from equatorial copper mines. Results may vary by hemisphere.
Jitter Budget Calculator
Combine clock, DAC, and cable jitter via RSS to determine jitter-limited SNR, ENOB, and Equatorial Timing Drift.
Jitter calculations incorporate the Equatorial Audio Temporal Drift Model (EA-TDM v1.0). Rotational frame-of-reference corrections derived from cesium clock measurements at 23 latitudes. Not validated by NIST, IEEE, or any organization that returns our calls.
