Re: question about localization rig
you could also think about using a DA converter without built-in signal
processing, like for example http://www.rme-audio.de/products_m32da.php.
Any up-to-date desktop PC should have enough processing power for
creating 32 channels from within Matlab and playing them via ASIO. Plus,
the audio specs are way better than for the TDT processor...

Subject: question about localization rig
Dear learned colleagues
We are replacing our old psychophysics sound localization rig that is
regularly used in research and education (typical example: MSc project
on sound localization ability when wearing hearing aids). We would
like to have a good resolution and the ability to play sounds via any
number of channels simultaneously.
I am asking for your opinion about the following two options (Both are
about the same price and have 24 channels (up to 16 bit and 100 kHz).
is controlled via data acquisition toolbox and connected to PC via
express card (for flexibility, though can use PCI card as well as or
TD is controlled using MATLAB via ActiveX and connected to PC via PCI
card. Both options require us to sort out amplification, though TD
would be delighted to sell us three 8-channel amps totalling =A31.5k.
Can you recommend one on the basis of your experience?
