Modern AI systems focus heavily on words and text. But in speech, singing, and music, the pitch of a sound is a vital quality that carries meaningful information about emotion and beauty. Merely decoding the words leaves us without a meaningful understanding of what we are hearing.

At Neocortix, we have 30 years of experience building wide-frequency-range and polyphonic pitch detection systems based on neuroscience, and using modern Machine Learning methods. This is an important part of building powerful AI systems that understand the world through sound.
