Absolute Band Powers?

Amazing project! Thought our new Muse (2016 model) would be unusable with our Mac/PC based neurofeedback apps until we found Muse-JS:)

As I understand it, Muse-JS reads raw EEG data from each electrode (TP9, AF7, AF8, TP10), but is there a simple way to read absolute band powers (delta, theta, alpha, etc.), or other data, from Muse-JS, without needing to manually decode the raw EEG data from Muse-JS?

I looked through your code, but didn't spot any way to simply parse or decode/compute band powers. Muse-IO & Muse Monitor both provided live band powers data (via OSC paths muse/elements/delta_absolute etc), as well as raw EEG data, but they're no longer feasible options & we'd love to consider using Muse-JS moving forward. Thanks for any feedback!

Thanks!

The device itself does not calculate the absolute band powers, it has to be done at the application side. You can check out neurosity/eeg-pipes by @alexcastillo as it might do the trick for you, I believe it can be used on top of muse-js with some adaptations.

@JT5D there are some examples on github, see:
https://github.com/tanvach/muse-fft (using eeg-pipes)
https://github.com/davinov/muse-js (using dsp.js)
