Audio Techniques | Sound Math vs Mic Polar

Audio Techniques | Sound Math The essential audio reference tool for sound engineers, audio professionals, and students. Wavelength & Period Calculator Enter any frequency and temperature to instantly see the speed of sound, wavelength in feet and meters, period, and phase timing at nine key angles from 90° to 330°. Adjust frequency with a slider or type it in directly. Audio Panning Calculator Visualize the relationship between stereo panning percentage and decibel levels. Slide between left and right channels to see real-time dB conversions with the underlying math on display. Timecode vs Frames Converter Convert between timecode (HH:MM:SS:FF) and frame counts at industry-standard frame rates including 24, 25, 30, 23.98, 24.97, and 29.97 fps. Essential for post-production and video editing workflows. Whether you're setting up speakers in a venue, mixing in the studio, or working in post-production, Sound Math puts the calculations you need at your fingertips — no internet required.

Mic Polar illustrates the directionality of all basic microphone types, in an interactive diagram. A linear or logarithmic polar plot shows the microphone's sensitivity for all directions. A linear plot shows the transfer function. Precise levels for certain angles can be found by touching the polar plot. Mic Polar supports omnidirectional and figure of eight, and anything in between. This includes all traditional microphone types such as cardioid and hyper cardioid. It does not include microphone with additional acoustic features, such as shotgun microphones.
