Audio Engineering Formulas
Audio engineering formulas relate level, frequency, and impedance across amplifiers, crossovers, and loudspeakers. These calculators help you match levels and design crossover networks accurately. They are essential for hi-fi, pro audio, and instrument design.
Audio Engineering Formula Calculators
- Audio Crossover Frequency f_c = 1 / (2π√(LC))
- SPL from Power & Sensitivity SPL = sensitivity + 10 × log₁₀(P)
- Audio Cable High-Frequency Rolloff f_3dB = 1 / (2πRC)
- SPL from Pressure SPL = 20 × log₁₀(p / p_ref)
- Crest Factor CF = V_peak / V_rms
- Reverberation Time (RT60) RT60 = 0.161 × V / (α × S)
- Total Harmonic Distortion THD = √(V₂²+V₃²+V₄²+V₅²) / V₁ × 100%
