real distance in spat

Hello,
Does anyone know what’s the real distance in meters for xyz speakers coordinates speakers xyz 1 1 1 does it mean the speaker is 1 m in 3D from the listener??
Thank you
Cheers

Hi,

If your speaker coordinates is (1 1 1) in cartesian (xyz), then the actual distance from the listener would be dist = sqrt( x * x + y * y + z * z ) = 1.73 meters.

However, in most cases, the speaker distance is not used by Spat. Only the speakers’ directions (i.e. azimuths and elevations) are relevant.
(although the relative distance between the loudspeakers is important and it can be compensated using spat.align~)

Cheers,
T.
