I remember many, many moons ago when I was CE at Z100, being invited into the PD (Steve Kingston's) office, and being played a cassette tape of some unknown station, and then being asked "can you make us sound like this?"
Some posts on this thread remind me very much of that episode.

There were no points of reference, nothing to go by other than the subjective qualities of the sound I was played. It didn't matter whether it sounded good or bad, nicely processed or not, the point is that I had no way of really knowing the circumstances of the recording, how competitively loud it was on the air or a multitude of other variables...
So I guess, to a very large degree, I'm with Frank.
On the other hand I myself can't seriously imagine that anyone would make a purchase based upon hearing a downloaded sound file purported to be of a product, adjusted by someone else, with program material they may not be familiar with, recorded on unknown equipment.
Yeah, it's better than comparing cassette tapes, but by how much it's not fair to say...
While I have kept up with this thread from the beginning and I do read it every few days, I have yet to listen to any of the files. Not because they may not be entertaining (no doubt they probably are!), but because, simply, all the variables make any serious judgment near impossible and any conclusions pretty much irrelevant.
Now, that being said, I am not so steadfast in when it comes to the comparison of recordings of the processing of online streams, rather than received broadcasts.
In that case we are somewhat closer to comparing apples to apples, since it is possible to make a relatively representative copy of what the stream sounds like. But also in that case, it might be more useful (not to mention simpler) to just point us to the address of the stream itself, so we can listen live, for as long as we want.
Kind Regards,
