An echo of a shot is not noise. It’s the actual sound of the shot bounced off a surface to be heard again after the direction of travel changed. And it can be heard again for a third time if it bounces off the right surface to be heard a third time by the listener.
I'm not 100% sure but, to me, it sounds like you're confusing a ricochet with an echo? A ricochet is when a physical object strikes a surface and it (or a part thereof) changes direction whereas an echo is when a sound bounces off something and changes direction. Sorry if I got it wrong but it sounded that way...
No, I am not. Do you understand acoustics at all? An echo is the sound waves of the originating shot the changes direction after bouncing off solid surfaces. The sound wave will go down range. If it hits an object, the sound wave will change direction. It can be easily confused as a shot coming from a different direction. Why? Because it’s an actual sound wave of a shot bouncing around.
Which is exactly why it's easy, to the trained ear or using software, to differentiate between a gunshot and a ricochet. The soundwave weakens as it travels and can sound different as it distorts depending what it's bouncing off, if I recall correctly...

Translation: by electronically altering the audio recordings, I can make you think there is something"fishy" going on. This is just like the UFO "experts" who manipulate images to "prove" the amorphous blob is a spaceship.

Honestly it doesn't take much more than some software on a computer and a bit of math. There are plenty enough recordings to get audio from and gunshots are pretty easy to ID as well as the hits on pavement as most of the recordings came from where bullets landed. I wouldnt believe it unless it was corroborated by other experts though.

That is an article about putting the output from a mass spectrometer through an audio amplifier for fun. They have example of what Ibuprofen "sounds" like.
A mass spectrometer is not used to analyze audio.
