Binaural audio reproduces ear canal signals from real or virtual scenarios.

Evidence

Binaural techniques are loosely defined to be methods that aim to reproduce accurately ear canal signals recorded in a real acoustic scenario with a real subject, or to reproduce ear canal signals which would occur in a virtual world. This is done by recording sound from ear canals or by utilizing measured or modelled head-related transfer functions (HRTFs) and acoustic modelling of listening spaces. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1916

Categorization

• DEFINE: Gives a working definition of binaural technique centered on reproducing exact ear-canal signals.
• corroborated: 2 independent passages support this claim — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1916
• XREF: connects to: Binaural microphones capture exact tympanum signals but depend on one’s own head shape; Computer simulation can now reproduce everyday impact sounds convincingly; Source distribution perception is hard because ear-canal signals sum before analysis (+5 more)
