 Posted: Sep 17, 2015 2:51 AM Post subject: BioEra audio capabilities |
|
I just discovered BioEra, and am really impressed with its modularity and capabilities (not all of which I understand yet!). I would like to design some protocols where there are several neurofeedback audio signals (e.g. for delta, theta, alpha, beta amplitudes) that can be delivered separately to the speakers of a surround sound system. I would like for the volume of each signal/speaker to change independently of each other, in accordance with signal strength. Is this possible in BioEra? Are there any example files I could consult to point me in the right direction?
Thank you! |

Yes, it should be possible.
See the BinauralBeats.bpd example design, it plays audio sounds on 2 speakers, different frequency to each stereo channel.
Then, in order to play on more than one speaker pair, you can select the target audio in PCMAudioPlayer.
One PCMPlayer can only play stereo audio (2 speakers) so I am not sure if surround sound system can be controlled that way (I have never done that). But it is possible to have several PCMPlayer elements in the same design, so that way more than 2 channels are possible (if they belong to different devices). |
