Can any science geek answer a couple of really stupid questions for me?
1. Am I right in thinking the audio is a snippet a day for the two year period, like a time lapse video? So the “sound” we “hear” for a few seconds would have been heard continuously from say the 150th day of 2014 to the 250th?
2. If that wave encountered a planet with an atmosphere like ours and no geomagnetic protection, would the wave have been able to excite the air to the point that a person standing on that planet could hear it??

Well, I’m not sure an atmosphere like ours could exist without a magnetosphere, but let’s say it could. Any wave can induce sympathetic vibrations in a medium, but there is only a very narrow range of electromagnetic frequencies that could be audible to us.
Usually, when they play sound clips like this, the actual EM frequencies have been sped up or slowed down until they are in the audible range so that we can listen to them. If these vibrations were right in the audible “sweet spot” naturally, then yes, you might be able to hear some sound when they hit an unshielded atmosphere.
