Quiztones is a frequency ear training app for amateur and professional audio engineers and musicians. Quiztones uses frequency-altered tones, noise and musical loops to train your ears and help develop more acute listening and frequency recognition skills.
Quiztones cleverly uses quizzes to engage users in training exercises. Each EQ Quiz includes three trainers: easy frequency boost, hard frequency boost, and hard frequency cut.
Four Quiz Packs are available via in-app purchase including: Orchestra, Strings 2, Electric Guitar, and Bass.
