I just want to know how a person from the audio can determine what is the sound of an originated shot and an echo of a shot? How do you know what shot sound to analyze and base calculations from?
Mike used his mass spectrometer to get a precise record of the sound waves, then he said he eliminated the "noise" part of the sound from gunfire sound wave.
I am no expert at this, but aware of the ballistic table for 223, 308 because I re-load my ammo.

Honestly it doesn't take much more than some software on a computer and a bit of math.

If different people were firing, there will be different types of ammunition found, by clinicians and/or by site investigators. So let's see if anything turns up to support this claim.

No. Sorry. Just no.
Your opinion? Not important. Sorry. Just not important.

Applications of Mass Spectrometers
Mass spectrometers are sensitive detectors of isotopes based on their masses. They are used in carbon dating and other radioactive dating processes. The combination of a mass spectrometer and a gas chromatograph makes a powerful tool for the detection of trace quantities of contaminants or toxins. A number of satellites and spacecraft have mass spectrometers for the identification of the small numbers of particles intercepted in space. For example, the SOHO satellite uses a mass spectrometer to analyze the solar wind.
Mass spectrometers are used for the analysis of residual gases in high vacuum systems
