Golden Ears

An audio ear-training course for recording engineers, producers and musicians. Moulton started doing such training as an educational exercise for students back in 1969, and has since used it everywhere. In 1992, KIQ Productions asked Moulton to make it commercially available, and the rest is history.

I'm personally very proud of these drills, and pleasantly surprised and honored by how widely they've been adopted and put into use around the world. Many private individuals, studios, broadcasting organizations, colleges and universities have all adopted Golden Ears. I know of nothing else like them, except for a couple of very specialized and highly developed in-house computer programs for ear-training. Certainly nothing else that is commercially available. If you want to improve your audio hearing acuity and knowledge, these are a great tool!
Vol. 1: Frequencies
Trains you to recognize boosts and cuts in all ten octaves of the frequency spectrum. Progressive drills build from simple boosts in music to more demanding single octave cuts in pink noise.

Vol. 2: Effects & Processing
31 possible signal processing changes, grouped into simple families: amplitude change, gross and subtle distortion, slow and fast release compression, equalization changes, stereophony anomalies and time-delay / reverberation settings.

Vol. 3: Delays and Decays
Delay settings from tenths of a millisecond to whole seconds; panning / slap / spaciousness effects -- in mono and stereo, on sustained and transient sounds. Reverb parameters -- predelays, decay times, etc. Invaluable when creating programs.

Vol. 4: Master frequencies
Advanced EQ. Identify cuts and boosts to within a third of an octave; and two octave bands simultaneously boosted and/or cut.
...the music business is about sound, and anything that can help you capture and manipulate better sounds merits a look. After repeated listenings, I was actually able to discern which octaves were being cut or boosted in the frequency drills... after getting over my terrible score, I realized that the ability to identify small nuances in signal processing can help fine-tune a good mix, or even save a tough one... The more you listen, the better you become.

The AES Student Section at Full Sail Center for the Recording Arts is excited to provide the Golden Ears eartraining Program to its members as a great complement to their real world education.

...Golden Ears has given me the confidence to tackle some of the most exciting and demanding projects... [Golden Ears] provided me with an understanding of the audio post and sweetening needs... to work on the sound design for the world's largest Omnimax theater... after working at the eartraining course, mixing, synth programming and sound design just became second nature. I will request that it be a required text for all students.
