  • short MIR-Preview-video

    I did have a look at the "short MIR-Preview-video".

    It looks like all the samples are based on empty halls.

    For what I know many halls sound too reverbereting if there are no adience and musicians inside.

    For example, some  high frequency tones could be lowened by the musicians bodies.

    How can you recreate all these absorptions in asample of an empty room?

  • That is an interesting aspect. However I think it is pretty much impossible to make IRs with human beings in the space. But interesting nevertheless .... best

    This certainly won't apply to spaces that pre-date modern acoustics (for example, cathedrals), but I believe it's been standard practice for a while now to fit concert halls with seating that has similar sound-absorbing characteristics to a human body, such that the size or distribution of the audience shouldn't noticeably affect the sound of the hall. 

    It would be interesting to find out which halls that have been sampled actually have this property, though.

    I don't see why, other than the logistical complications of getting a load of people to sit there quietly during the sampling process (although removing any squeals they make when bangs go off could be amusing).


  • The sampling session for all MIR impulses takes up to 16 hours only for one hall.

    Don't forget there have to be hundreds of impulses recorded.

    The noise of the impuls generator is hurting  your ears extremely.

    And at least the all seats of the Konzerthaus are prepared to "simulate" people sitting there.

  •  That could give a nice picture: a room full of mannequins [:)]

    Indeed. Many auditoriums have seat cushions that are designed to have the same acoustical absorption properties as the human that would otherwise occupy the empty seat.
