What people are saying

  • The success of a musical performance depends on the sense of proximity of performer to listener. This sense is mediated largely by the directional properties of the reflected sound field.

    Sir Harold Marshall
  • I regard the acoustic designs of Marshall Day Acoustics to be amongst the finest and probably the most innovative in the world.

    Dr Anders Gade, Technical University of Denmark
  • Marshall Day Software is like having an acoustic laboratory in the palm of your hand.
