OSC streaming frequency

Post by nimbinensis »

The OSC specs say that the absolute data for each of the sensors is being sent at 10HZ. Does that mean that I'm going to get a full set of data every tenth of a second. What I mean is, is the data for all the sensors bundled up in a single record and sent in one go, or does the data for each sensor come separately?

The reason I ask is that I'm using Processing to write a display program and they way Processing works is that it loops the draw() function unless you turn it off and on. If the data is all bundled together it makes this reasonably easy but if each sensor's data comes separately then I have to look at buffering or something like that.

Unless, of course, I've misunderstood how OSC works. I've only just started this project so that's not unlikely. ;)

Each absolute comes in separately at ~10Hz.
You can see the OSC spec here: https://musemonitor.com/FAQ.php#oscspec
Each OSC Path has it's own asynchronous timing.

Hi James,
what about the EEG RAW sampling frecuqency?
In the OSC specs it is written 220Hz | 256Hz.
What does this mean? How do I know if it is streaming at 220 or 256?
Thanks :)

The 2014 Muse 1 model MU-01 is 220Hz, all the others are 256Hz.
