I made the first three videos below from the audio on fourth video. I extracted the audio, then edited it and screengrabbed it while it played back in my Lexis Audio Editor, then mixed the audio with the screengrabbed video. I think it helps be be able to “see” the audio as you hear it.
The first is what the human ear would probably hear from the wind on Mars. YOU PROBABLY CAN’T HEAR IT WITHOUT GOOD HEADPHONES, TURNED UP LOUD! It is very low frequency, and if you have good headphones and turn it up to max volume, you ( I ) seem to “feel” it in your ears more than hear it. You can see it’s quite a large signal, but it’s near the lower limit of human hearing, therefore hard to hear. I find it fascinating.
In the second video, the audio has been pitched up two octaves, placing it easily within the human audio range. (Remember, you might still have your headphones all the way up and may want to lower the volume a bit)
In the video below, the sound comes from a different instrument on the InSight lander, and has been multiplied by 100, thereby increasing the frequency by 100. It sounds really weird.
The video below is the story that was all over the news, you’ve possibly seen it already. Like I already said, the audio for the first three videos came from the audio in the video below. Their explanation is much more thorough than mine. You’ll hear all the same sounds as in my videos again, but I like my videos because there is a good visual reference to go with the sound.
Hope you enjoyed this post, I enjoyed making it! It took quite a lot of work and I hope you’ll leave a comment!
