Spherical Arrays for Analysis and Synthesis of Radiation

[semente]

Interesting presentation on recreating the soundfield of a recorded instrument in the listening room using spherical arrays.

Ths looks interstign but I'm not 100% following. Are we using a single spherical louspeaker array to respresent one single instrument?

Just noting the physical similarity.

Yes, record the instrument soundfield inside a spherical mic array cage in an anechoic room and reproduce the soundfield with a spherical speaker array in a resonant environment to replicate the real instrument.

It's an exciting idea.I wonder if it would work for something as large as a grand piano.

You could get this instead:

 

 

My son is learning to play, I'd get one if I had the room and the money...

How much are they. It reminds me of that series of recording where they got a player piano to play (supposedly) the manner of famous histroic recording such as Rachmaninov playing his own stuff.

The only reason I asked aboiut the piano is that I cant honestly say I listen to that much in the way of solo violin or cello (outside the bach sonoatas and suites, and a few of the big violin sonatas. But solo piano is another matter

A previous neighbour's piano used to play those Zenphe recordings:

 

The cheapest is this upright at £11.5k, just about the price of a pair large standfloor speakers:

How about a hundred of them to record and play a symphony orchestra?

Might be cheaper to hire an orchestra...

Not if you also needed a conductor. ?

Especially if you insist on using silver conductors.

Ah, yes.  The old and experienced have the capacity to charge more.
