      "content": "<p>Very cool idea!  <br>\nThese are all 4 seconds long at 44.1 kHz rate.  Does that mean that the original 200 Hz data rate is being played about 220 times faster? So a 10 Hz alpha wave in the data would be at 2200 Hz in these? And a 50 second event would last only ~ 1/5th second in this audio?  If this is true, then it might be more useful to scale the 200 Hz by only a factor of 20, say, and use a wav rate of 4.0 kHz (I believe WAVs can have arbitrary sample rates.)</p>",
