Ear training application that allows you to develop two basic skills for every sound engineer: ability to recognize basic waveforms types at different fundamental frequencies and an ability to recognize applied equalization to an audio material.

Features:
- sinusoidal, triangle, square and sawtooth waveforms with fundamental frequencies from 63 to 4000 Hz (octave steps)
- 9-band equalizer with octave bands from 63Hz to 16kHz
