Post-Ut is a free, web-based, on-line sonic measure ear training system. Post-Ut teaches the language and metrics of sound and sonological study. Questions, using both multiple choice and free response, test selection and identification of frequency in Hertz, amplitude and dynamic range in decibels, rhythm and time in milliseconds, semitone and quarter-tone intervals, and spectral density. All questions employ audio examples drawn from a large database of high-quality, algorithmically-generated and processed audio files, employing both synthesized synthetic sounds and processed acoustic sounds from The Freesound Project. Post-Ut provides aural training for computer musicians, audio engineers, and sound designers.

"The danger is great of letting oneself be trapped by the tools and of becoming stuck in the sands of technology that has come like an intruder into the relatively calm waters of the thought in instrumental music."
