- Decibel Addition CalculatorEnergy summation of levels; geometric spreading per ISO 9613-2Decibels are logarithms, so they do not add. Two machines at 85 dB each do not make 170 dB, and they do not make 85 dB either -…
- Audio File Size CalculatorLinear PCM in WAV/RIFF; RF64 per EBU Tech 3306 above 4 GiBUncompressed audio has no surprises in it: the file size is exactly the sample rate times the bytes per sample times the…
- Speaker Impedance CalculatorRated impedance per IEC 60268-5Wiring speakers together changes the load the amplifier sees, and getting it wrong is the fastest way to destroy an output…
Which one do you need?
- Decibel Addition Calculator
- Add sound levels correctly on a logarithmic scale, see each source's share of the total, and apply a distance correction for point or line sources.
- Audio File Size Calculator
- Work out uncompressed recording size from sample rate, bit depth, channels and length, compare it against a compressed target, and see how long a drive will last.
- Speaker Impedance Calculator
- Work out the load an amplifier sees from speakers wired in series, parallel or series-parallel, check it against the amp minimum, and see the power in each driver.
