I have a MindWave headset that reads brain waves and transmits them via Bluetooth. I am sending OSC data to PureData which either generates audio or sends Midi data.

The problem is, the data jumps around and it is difficult to tell how it is trending. I'm thinking if I could do a running average of the incoming data, it would be more usable. The data comes in on one second intervals.

I would appreciate some feedback on how to accomplish this in pd.

General feedback/suggestions appreciated.

Thanks,
Tom

Tell me what you think of Dan Winter's toolbox for biometric measurement of 'internal auto-Coherence':

Is there any way to see the patch? I'm trying to do the same thing.

If you are using pd-extended, you can use the mapping abstractions.

For an other project I had the same problem. I solved it by cheating a bit and create an object with Tcl code using TclPd:

The help patch is here: http://fjkraan.home.xs4all.nl/digaud/puredata/tclPd/countingAveragerTcl-help.pd

For performance comparison I also recreated it as a Pd patch. I remember the latter was more efficient (most functionality in c-coded objects).
