Eigenmike encoding, issues with order 1 and 3 components

Spat
#1

(edit: sorry, I don’t know why I switched to french)

Hello everybody!

I have an eigenmike recording, 32 channels. I would like to encode it and decode it with spat. When I use spat.eigenencode~ @order 4 (no mater what the order is, the same issues happen), the outputs for orders 1 and 3 are noise, is that normal?

It is not white noise, and I don’t think either it is a issue with the buffer size (I tried different buffer sizes, up to 2048 samples. Example of this noise enclosed.

Would you have any idea? I could use the MH acoustics encoder but I would rather do everything in spat if possible.

Thanks,

Laurent

Hello Laurent,

The spat.eigenencode~ object currently shipped with spat is quite buggy.
To be honest, this was an early prototype and I’d recommend not to use it.

The object/algorithm has been completely revamped and it will be included in a forthcoming major release.
I’ll send you a private beta shortly.

Best,
T.

Great, thank you!

Have a nice day.
