I am doing research on P300 speller and the sound from different spatial directions, such as left, right and forward directions.
Do BCI2000 support to play different sounds respectively using speakers in different directions and how to connect multichannel sound card? many thanks.

Haibin,

Funny you should mention it, I'm actually actively developing a module to handle multichannel audio I/O in the signal source module called the "AudioExtension"

I'm hoping to have a public release in "Contrib" in a month or two. This is essentially a wrapper for portaudio in BCI2000 and enables working with multichannel sound cards and any number of audio APIs (including low latency APIs such as ASIO on Windows, and CoreAudio on OSX)

BCI2000's audio engine currently runs in stereo with DirectSound, and doesn't provide much control. Eventually, I believe the AudioExtension will become a framework addition which will give the developer/user full control over audio I/O and function in a cross-platform way.
