Music & Audio Calculators (10)

Musicians and audio engineers both live by real numbers, which is why this collection starts with a bpm calculator that converts tempo into delay times for reverb, echo, and other time based effects. From there, work out chord intervals for any key, the exact frequency in Hz behind any musical note, and how loud a sound really is with a real decibel calculator, plus a tuning fork reference for accurate instrument tuning.

There is also real coverage for the technical and business side of audio: sample rate and bit depth math for figuring out a file's real size before you record or export, speaker coverage area for planning a room or venue setup, headphone power requirements for driving a specific pair correctly, and two calculators built for the music business itself, a record label deal split calculator and a live event ticket revenue calculator for working out what a show or release actually pays.
