A marching band plays a few meters away with crisp cymbals and sharp flutes over pounding bass drums. The scene cuts to several blocks away, where only the bass drum and tuba carry through.

Key standards

Visual physical commonsense (V-PC)

  • A near-scene shows a marching band actively performing with instruments held and visibly played, and a separate scene shows the same band visibly several blocks away.

Audio physical commonsense (A-PC)

  • In the distant scene the high-frequency cymbals and flutes are noticeably attenuated while the low-frequency bass drum and tuba carry through.

Cross-modal physical commonsense (AV-PC)

  • The audible instrument spectral mix matches the visible proximity of the band in each scene.
