Some actually believe that music from different drive types (SSD,HDD) or different SATA cables can sound different

At the axis.

You can stick that through the sphere in any direction, and it will all look the same, though. Same for a line drawn tangent to the sphere-it looks the same no matter where on the sphere you place it.

In this particular case, this was in neuroscience, looking at/listening to the electrical signal generated by a single brain cell, which drowns in noise from the surrounding cells and, well, a ton of other noise sources. A cell firing looks a whole lot like the type of artefact antcollinet's screenshot shows. One (or usually a couple of, depending on sampling rate) sample clearly sticking out amongst the surrounding signal.

Not really: 1 full scale sample sticking out of 'noise' with .9 amplitude is harder to spot (both visually and audibly) that one full scale sample against .3 amplitude.

Weren’t we talking about musical signals? Also “harder” is not impossible. We have all sorts of tools for expanding signal charts in the time and amplitude directions.

Yes, but the similarity between what a brain cell signal can look like and single FS samples in music is rather striking so that set me off.
Plus, as some of the more eccentric people in the field would say: brain cell signals are muscial

Storing, its not emi or rf or anything else it's IRQs and poor software driver design that causes the audible glitches.

I guess that I'm not supposed to be facetious?

I 'spoze.

Wait, is this limited to stand alone audio CD players or also including CDrom trays in old 90s computers? Back in the day, one dared not even think about playing Minesweeper lest it puke. Win95/IDE/IRQs sucked hardcore.
You really wanted a SCSI or later Firewire for PC based systems.

Indeed. Sometimes file I/O could just freeze from seconds to a large chunk of a minute.
Especially if one had external serial port drives such as a ZIP connected.

Well, technically, nor does an amplifier or even, say, a reel to reel tape recorder/player.

Well of course you are correct about the CD anyone tried a CD knows that small scratches or stains causes errors in the playback artefacts and sound errors. That is not happening inside a computer if a file is not read correct you receive a read error. This is what happen if you have a failing hard drive. The system crash if you try to execute files from it no matter if it is SSD or a magnetic. Random read and write errors is not a working condition for a computer but a serious condition that cause recurring crashes and failure, a audio CD has a much different system trying to read and accepting errors and trying to play after the misread bit. The idea of selling special things for computer drives that are more hi fi is a scam..

The development of "special things" are why we no longer need to have forklifts to move around our IBM 350 Disk File.

If you're talking modern/external soundcards then yes, that's usually just chunks of the audio stream being skipped.

My original example was old on-board soundcards though, and that was definitely (also) EMI: audio plays fine, no glitches, but extra audible signals being mixed in when certain peripherals and/or main data bus being used.

The forklift industry has probably never recovered.
