hearEQ is a powerful app that helps you develop your EQ skills to professional levels through custom ear training exercises. Designed for sound engineers, musicians, and enthusiasts, hearEQ allows you to learn the qualities of each frequency band and apply them to equalization, transforming your sound into something professional and beautiful.

Using your favorite songs on your iPhone, hearEQ creates custom ear training exercises that teach you about frequency bands and help you hone your EQ skills. The app uses a standard 10-band or 30-band equalizer, similar to what you would find in iTunes or professional sound mixers. Your chosen song is played back with an equalization applied, and you have to guess what adjustments were made.

With ten questions and ten frequencies to identify, hearEQ provides a score to track your progress. You can also focus on specific frequency bands to start and gradually become an EQ master. The app even includes an "Advanced EQ" module with a 30-band equalizer available as an in-app purchase.
