Discriminative Frequency Training - Full Octave Bands

Switch to : 2/3 Octaves  (difficult)

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

Training Files

The audible spectrum has been divided into 10 bands (octaves spacing), from 30Hz to 16kHz. Listen to each octave and try to associate it with its respective center frequency.
