AcoustiCal is a complete calculator for the most common acoustic problems. Whether you are a sound engineer or an audio hobbyist, this is your tool. With AcoustiCal you can easily perform the following operations:
- Convert between frequency, period and wavelength
- Convert between time and distance traveled by the sound
- Convert between frequency, phase and delay
- Sum of SPLs (coherent and incoherent)
- Convert between dB, dBA and dBC
- Compute the attenuation of the sound at a given distance
- Compute the attenuation due to the air
- Calculate the resonant frequency of a Helmholtz resonator
- Calculate and visualize room modes
- Calculate and visualize the reverberation time in a room with given materials
- Convert between Volts, dBu and dBV
- Convert between Watts, dBm and dBW
- Perform Ohm's law calculations
- Convert between peak and rms volts
- Have a resistance color code calculator at hand
- Calculate the sound pressure level of a loudspeaker at a given distance
- Convert between loudspeaker sensitivity and efficiency
- Calculate the needed power for a given SPL
- Have a simple sound generator with the most common waveforms for acoustic measurements
- Convert between filter bandwidth and Q factor
- Calculate the -3dB cutoff frequencies of a filter
