Mind Monitor

Wikipedia has a very good article on Fast Fourier Transforms (FFT). If you've not heard of FFT then it will likely be a steep learning curve for you. I would recommend using something like processing.org to play with the data.

If you wanted to, you could read the data files as they are being written, but there will be periods of time during which is data is not flushed, so that's not something I would recommend. You would be better of writing your own app to directly connect with the Muse headband.

There is currently no way to record directly to a spectrogram. However all the data in the spectrogram is interpreted data created from the RAW data, which is recorded. As such, you can re-create a spectrogram from a RAW data recording. To do this, perform an FFT with a hamming window function.

This is a real time graph, so you would have to watch it and see
Instead switch to the spectrogram, which displays discrete frequency data plotted over time.
Use a two finger touch to adjust the maximum and minimum magnitude range values, to tweak the spectral output.

To see a specific frequency, switch to the discrete frequency graph, shown below.

You can then read off values for each individual frequency. For example, the approximate 7.5-8.5Hz area is circled in red.

Muse Monitor was designed to be compatible with Muse Lab as a receiving OSC Server, so it uses all the same address patterns as Muse-IO. These are detailed in the Interaxon docs here: http://developer.choosemuse.com/research-tools/available-data If you're using Muse Lab, I have a configuration file ...

I have added this to Muse Monitor. However, you should note that the timestamps reported by the Muse API are not 100% accurate. The timestamps appear to not be being generated by the hardware but by the LibMuse software API and as such are subject to processing overhead and bluetooth stack buffering...

#1 You must be on the same network. #2 Muse Lab must be listening and not be blocked by your firewall. Once you have done that, open Muse Monitor; Enter your laptops IP in the "OSC Stream IP" and press the stream button. There is a same configuration file for Muse Lab which will setup ever...

Not folders, but in the settings you can change the "filename prefix" to the client's name. This should do what you need

The Muse can only connect to one app at a time. Before running Muse Monitor, terminate the Interaxon Calm app by double tapping the home button, then swiping up on the Calm app to kill it. You can now run Muse Monitor and get a connection.
