About this app
Audio Calculator Precision Built for Pro Audio. Audio Calculator Pro is the ultimate toolkit for audio engineers, sound technicians, system integrators, and musicians. Designed for professional field and studio work, this app provides over 60 mathematically verified calculators based on industry standards. Why Audio Calculator Pro? • 60+ Professional Tools: From complex acoustics to electrical engineering and RF analysis. • No Subscriptions: Buy once, own forever. Professional tools should not come with a monthly bill. • Offline First: No internet? No problem. All calculations run locally on your device - perfect for festivals, remote locations, and studios. • Smart Bidirectional UI: Calculate from values to dB or vice versa with synchronized smart fields and intuitive sliders. KEY FEATURES Acoustics and SPL • dB Toolkit: Professional conversion for dBu, dBV, dBm, dBW, and SPL. • Distance Law: Visualize level drop over distance. • RT60 Reverb: Advanced Sabine and Eyring formulas with automatic recommendation based on room absorption. • Sound Speed: Environmental adjustment for temperature, humidity, and pressure with a real-time velocity gauge. • Air Absorption: ISO compliant atmospheric attenuation. Electronics and Cables • Speaker Cable Analysis: Calculate power loss in percent, voltage drop, and the impact on the system damping factor. • RF Cable Attenuation: Frequency-dependent damping for standard antenna cables like RG58, Aircell, LMR-400, and more. • Ohms Law: Interactive wheel for power, voltage, current, and resistance. • Impedance Vector: Visualize complex resistance with dynamic vector diagrams. Microphones and Recording • Stereo Recording and SRA: Interactive Williams Curves visualizer for ORTF, NOS, XY, AB, and custom setups. • Microphone Arrays: Design linear and circular arrays with optimal spacing to avoid spatial aliasing. • Sensitivity: Convert between mV/Pa and dBV/Pa. Music and Signal • Frequency Analysis: Musical pitch detection, Cents deviation, and Wavelength mapping. • Harmonic Series: Visual overtone spectrum analysis and THD estimation. • Tempo and BPM: Precision beat-to-time conversion for FX sync and delays. • Comb Filter: Visualizing constructive and destructive interference caused by time delay. ENGINEERED FOR ACCURACY Stop guessing and start calculating. Whether you are tuning a line array, designing a crossover, or calculating RF loss for wireless mics, Audio Calculator Pro delivers the mathematical precision you need. One-time purchase. Professional precision. Own it forever.
