Auricula Ear Training Plug-ins are crafted to enhance the listening skills of audio producers and engineers by challenging their ability to identify audio manipulations. Users provide an audio file, which the plug-in automatically alters in some way, and then they must determine the nature of the changes by ear. With consistent practice, this interactive approach sharpens the ability to discern subtle audio details, improving overall auditory perception.

The suite includes specialized plug-ins focusing on different aspects of sound. Helices and Helices Pro concentrate on frequency recognition using a variety of filter types across multiple octaves, helping users identify EQ changes from broad to very narrow frequency bands. Incus addresses stereo field alterations, training users to detect common mix issues such as phase reversal or channel imbalance. Meanwhile, Malleus emphasizes understanding gain changes measured in decibels, an essential skill for precise level control in audio production.

Additional tools like Stapes focus on recognizing time delays and their unique sonic effects, while Concha offers an advanced EQ challenge with customizable parameters including frequency, gain, and filter type, increasing difficulty as users progress. Meatus simulates various reverberation environments, enabling users to identify different acoustic spaces and artificial reverbs on individual tracks. Together, these plug-ins provide a comprehensive training experience designed to develop critical listening skills essential for professional audio work.
