Decibel (dB) Calculator Turn a ratio into decibels or decibels back into a ratio, with the right factor — 10 log₁₀ for power, 20 log₁₀ for voltage or current — plus the named reference levels (dBm, dBW, dBV, dBu, dBµV, dB SPL) and what your gain does to an absolute level. RMS, Peak and Peak-to-Peak Converter Enter any one of RMS, peak, peak-to-peak or rectified average and get the other three, for a sine, a square, a triangle, a rectified sine or DC — with each shape's crest factor, form factor, power into a load, and how far a cheap average-responding meter will be out. Speaker Impedance Calculator (Series and Parallel) Total impedance of up to six drivers in series, in parallel or in series-parallel, the power each one takes from your amplifier and the total the amplifier is being asked for — with a warning when the load you have built goes below the minimum your amplifier is rated for.
