Interpolate incoming Data (NeuroSky MindWave 2)

General TouchDesigner Discussion

Hi,

I am currently doing a project with TD and the NeuroSky MindWave 2 Headset, connecting it to TD with OSC.
The EEG data updates approximately every second and I don’t think there is a way to get it more frequently. (If you have a solution let me know!)
For my project I need a smooth signal (waveform), so I just want to interpolate the incoming data that it looks smooth.
I tried a lot of CHOPs but I just don’t get the result I need.
(Should mention that I am still a beginner, maybe there is a obvious way I don’t see.)

I hope somebody can help me, thanks in advance!

Hello,
One possibility would be to use lag CHOP, if you see in operator snippet, there is some good examples. But you will have some delay.

Have you tried filter Chop? I find it better for this than Lag.

Filter chop works perfectly for my purpose! So easy…
Thank you very much!

Hi, I am tring to import the data with OSC in. I tried several ways but they all failed. Would mind to share the experience about how to import it?
