Take your point, but even the recording is 'processed' by definition.

Seismometers measure frequencies in solids ground motion (quakes, volcanic activity), audio is measuring in liquids and primarily in gases which fit the human hearing frequencies.
Same principal, different mediums. As you say, all processed one way of another.

If a tree falls in a forest, does it make a sound?

No, it vibrates the air, it needs an ear to covert those vibrations to sound and a brain to comprehend them.

What is an ear? Is it a seismograph? Is it a microphone? Is it a speaker? Is it a human ear? Is anything real?

I believe the frequencies recorded by the seismometer had to be sped up and increased in magnitude to create a sound that the human ear can even register.
