Quiztones is a frequency ear trainer for amateur and professional audio engineers, producers, and musicians.

Quiztones uses tones and frequency-altered noise and musical loops (including source material from your own music library) to train your ears and help develop more acute listening and frequency recognition skills.

Quiztones will...

• Sharpen your ears & frequency recognition skills
• Improve your mixing and EQ chops

Quiztones cleverly uses quizzes to engage users in training exercises.

Each EQ Quiz offers four trainers:

• Easy frequency boost (+10 dB)

• Hard frequency cut (-10 dB)
• Expert frequency boost (+5 dB - 1/3 octave)

New In Version 1.7!

"As a professional audio engineer my most prized tool is my ears. Developing this acute sense of understanding can take years of development. With Quiztones, both aspiring and professional engineers alike can now develop and sharpen the skill(s) of 'truly musical hearing' while on-the-go. Quiztones is both fun and educational, merging the two into an addictive and beneficial mobile app."
