Notes:
"I received this in 1987/88 from a very well connected Bowie collector in the Netherlands 20 years. It has laid on this cassette in storage having only had about 2 or 3 plays since then and has never been digitised until now. It is a pretty good audience recording of Bowie first ever Florida performance and is a cracking show. It is far better than many other 72/73 audience recordings I have heard with a pretty good high response although perhaps a little boomy and with quite hot recording levels. It has has a few flaws i.e. occasional tape speed fluctuations, a little wow and flutter at points, some few small cuts in the tape, and a few instances of muffled mic noise between tunes but is pretty cool for the time and is a complete show".
It has the noise you would expect for early 70's audience recordings and the people near the taper talking here and there.

It was checked with auCDtect and says the files "looks like MPEG with probability 95%".
Considering the lineage of the original uploader, was a strange find.
There appears AIFF instead of WAV, so probably is a Mac user (no idea if that is relevant or not).
Then, I tried to do a frequency analysis and spectral view with EAC and it's not an uncompressed 44.1 kHz stereo WAV.
Indeed, it's 48 kHz/16 bit with a bit rate of 1536 kbps (instead the usual 1411).
If anyone could make frequency analysis and spectral view with other software, would be of interest.
In simple words, the quality of the transfer (but read the last comments) is superior to usual ones, although not the one you find in some vinyl rips, for example, 96/24 or 48/24. Also, it's quite sure these files could not be burned in a standard audio CD, unless you downsample them to 44.1/16.

An audio CD can represent frequencies up to 22.05 kHzóthe Nyquist frequency of the 44.1 kHz sample rate:
44,100 samples per second ◊ 16 bits per sample ◊ 2 channels = 1,411,200 bit/s = 1,411.2 kbit/s

here it is:
48,00 samples per second ◊ 16 bits per sample ◊ 2 channels = 1,536,000 bit/s = 1,536 kbit/s

To finish, I did same tests on the recent David Bowie 1973-01-09 Guildhall Preston UK (AUD), that is also 48/16, and auCDtect shows "track looks like CDDA with probability 100%". Then, something strange happened in the transfer that make the files to appearlike MPEG sourced.

Info:
"It is the first ever public appearance of 'Drive in Saturday' from the 'Aladdinsane' LP which was to appear in 1973". According to other info found, that is not true.
"Highly recommended if you like Ziggy era Bowie...Thanks to the original taper and to my contact in the Netherlands. I hope you enjoy this - I certainly did while converting it."
I agree for sure. It's a entertaining gig with a receptive audience.

I have added the original info text, info about the show at The Ziggy Stardust Companion, as well info about a silver from 1995 and another transfer from tape that was also uploaded to Dime. If someone could compare, would be of interest to know if they are all sourced or not from the same tape.
