Equalizer / Waveform button
During a training session, the Equalizer view displays the various frequency response graphs (your response / the correct answer), along with the Training Mode, Filter Type, and the parameter values of the correct answer if you were incorrect.
The Waveform view is used to import and playback audio files and switch between imported audio files or software inputs.
