Here you'll soon find step by step instructions on how to run alps...
...but for now, it's not so straight forward yet. But if you want to persevere, and you are a bit computer savy, get the code from here. As to hardware, you will need a (fast) soundcard, microphone(s) with a good signal-to-noise ratio, and loudspeakers with a frequency range upo to 30 kHz. Many loudspeakers do! We used Genelecs 1029A loudspeakers and dpa 4061 microphones. The less directional the loudspeakers and the microphones are, the better.
The other thing to have a good look at is the configuration file, which is pretty much all you need to tweak once the code is running. The comments in it hopefully help a bit. Please let us know how you get on via the blog
