Theory

192edo is closely related to 96edo, but the patent vals differ on the mapping for 7. Using the patent val, it tempers out the pythagorean comma, 531441/524288 in the 3-limit; the Würschmidt comma, 393216/390625 and the unicorn comma, 1594323/1562500 in the 5-limit; 2401/2400, 3136/3125, and 1594323/1568000 in the 7-limit; 243/242, 441/440, 5632/5625, and 131769/131072 in the 11-limit; 676/675, 1287/1280, 1573/1568, and 2704/2695 in the 13-limit. Using the alternative 192f val, 351/350, 1001/1000, 1575/1573, 3584/3575, and 5445/5408 are tempered out in the 13-limit.

Significance in digital audio

Its adjacent step is known as Tetramu (fourth MIDI-resolution unit, 4mu, 24 = 16 equal divisions of the 12edo semitone).
