CASA aims to extract all perceivable information from ear canal signals.

Evidence

Computational auditory scene analysis (CASA) refers to techniques that try to reveal all information from the ear canal signals accessible to a human listener. Music information retrieval, which can be seen partly as a subtopic of CASA, covers different techniques on how computers could recognize musical structures in audio tracks in the same manner as humans do and use this information to operate intelligently on music databases. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2557
