What will those MP3 fools think of next?!

Theres just something about the name Frauhfnahafheaurafer Institue that jogs your memory everytime you see it.

Did you find any actual pictures of the driver arrays?? I couldn't find any.

This is not the first attempt on that subject. And there is an article within the latest JAES dealing with wave-field synthesis.

I recently read an interesting article about virtual surround created using DSP that seems very credible or at least curious. Possibly related, not sure.

The main disadvantage of that procedure ist the reduction onto the horizontal plane of the listener because the speaker rows only mounted horizontal. That is very audible, because the strongly dampened rendition room hardly generates mirror sources outside this level.

I have an another proposal for a wfs- speaker field in front of the listener. By way of including the listener room properties into the synthesis the possibility for an physically sound filed reconstruction an all 3 Dimensions arise. The patented Procedure is described on my website.

To be fair mp3 was quite an impressive achievement

Hi Bigwill,

the IOSONO works by the wave field synthesis approach ( see http://www.syntheticwave.de/Wavefieldsynthesis.htm or wikipedia ).You need no normal audio signal like MP3, you must have a dry recorded single (mono) signal for each source. The synthesis builds up the spatial soundfield from that source signal and the spatial information, stored as impulse response or mirror source model. Standard are the MPEG4 based formats.
