![]() ![]() Each slave can be controlled independently to playback or record Instead one can create (multiple) slave devices that are attached to a Master devices themselves are not directly used to playback or capture You can also define a audio device as a master device by adding the value 8 to ![]() ![]() However no sound can be captured during this time and your code mostly doesn’t The speakers with minimal latency and without involvement of your script at all, This mode allows direct feedback of captured sounds back to Which only works for full duplex devices when using the same number of input-Īnd outputchannels. Hardware this mode may crash hard! There is also a special monitoring mode = 7, Mode 3 (full duplex) does not work reliably on all sound hardware. Can be set to 2 = audioĬapture, or 3 for simultaneous capture and playback of sound. E.g., Windows has about five different sound subsystems. Select the same physical device, but controlled by a different low-level sound To whatever the systems default sound device is. Select amongst multiple logical audio devices supported by PortAudio. OpenSlave?’ instead for a suitable solution.Īll parameters are optional and have reasonable defaults. If you feel the need to call ‘Open’ multiple times on the sameĪudio device, read the section about slave devices and the help ‘PsychPortAudio On most operating systems you can open each physical sound device only once per Open a PortAudio audio device and initialize it.
