Re: question about localization rig

[Tom Francart <tom.francart@xxxxxxxxxxxxxxx>]

Dear Stefan,

In our lab (ExpORL, KU Leuven), we use two RME Multiface II sound
cards (http://www.rme-audio.de/en_products_multiface_2.php), connected
directly to active loudspeakers. Any number of these sound cards can
be simply linked together and act as one ASIO sound card with many
channels.
The nice thing about using a standard ASIO sound card is that you
don't have to cope with any special drivers, toolboxes or ActiveX
nightmares.

On the software side we mainly use our APEX 3 platform, which can
easily be configured for sound localisation experiments. Cf.
http://www.kuleuven.be/exporl/apex for more information.

best regards,
Tom
