Discriminative Frequency Training - 2/3 Octave Notches

Switch to : Full Octaves  (easier)

Purpose

Equalization (EQ) refers to the process of altering the frequency response of an audio system or a sound file. EQ can be used for esthetic reasons or to compensate for unwanted bumps or holes in the audio spectrum.

The following files help you discriminating missing frequencies across the audible range. By training your ears to recognize those missing frequency bands, you will acquire the ability to locate unwanted frequency dips by ear and find the correct EQ fix in one go.

Training Files

Listen to each file and associate the missing 2/3 octave band with the value of its center frequency.
