Pedantry: "audio of first likely 'quake' on Mars" is unlikely. But "first likely audio of a 'quake' on Mars", sure.

Or "audio of first likey 'quake' on Mars (recorded by this sensor)"

Sure. But that's not in the title.

Sounds a bit like a rockfall to me, perhaps nearby? The slow buildup and slower subsidence of the sound intuitively fits what I would expect for a rockfall, and also we know there are rockfalls on the surface of Mars. It would be neat if that could be corroborated with surface evidence of a rockfall (I think a few have even been captured by satellite!) Impulsive quakes on Earth have a characteristic waveform which th…

There is no audio on mars, so they generated the sound.

The article states definitively that Mars does not have tectonic plates. This is news to me because hitherto I thought there is no evidence either way.

Plate Tectonics seems to require water , lots of water.

This is recorded from vibrations in rock, not in air. There is some sound in the very thin Martian atmosphere, and there is plenty of sound in the Martian crust.
