Quite interesting

i thought this sounded quite good but would like to hear your views on their work......

What will those MP3 fools think of next?!

 

[onis_uk]

hehehe i thought they were the people who thougth up the mp3 formatt

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.

only these ones ....

An externally hosted image should be here but it was not working when we last tested it.

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.

Absolutely.

I can't understand the bad rep it gets from some. With high bit rate Mp3's (320kbits+) its hard to distinguish between the uncompressed unless your really intently listening and doing AB's every few seconds. I don't tend to listen to music like that so for me its perfectly acceptable, especially for electronic and pop music that already isn't so pristine in quality.

...I woud agree 320kbits sounds good, but 32 kbits awfully

But the tread regards Iosono, a wave field synthesis based principle. The genuine sound field becomes restore according huygens principle. Show that short animation:
