To me this does not look like a direct transfer from reel. The blockiness along the 16kHZ line tells me this is lossy. I can be wrong on this one so we'll see what others will say. Can we get a FA shot to confirm.

If you look closely at the graph there is "noise" above 16kHz. Also the line of "blocky" @<hidden> 16 kHz seems very uneven compared to your normal lossy. Many peaks and troughs.
I hesitate to call this one. Considering the year, could BE lossless from average recording equipment.
Can the poster give more info about source; IE lineage.

Anyone else?

Its a audience recording done on a Grundig reel to reel recorder.
After some years it was copied again to another reel which would make it a 1st gen cause the master was deteriorate.
Then many years later it was transfered to a digital medium by the original taper but with the assistance of someone a bit more savvy on the modern day equipment.
So the lineage should be reel master>reel 1st gen>digital
Im worried though that either it was dont faulty and made lossy by accident which would surprise me considering what i know the person responsible for the transfer knows about the subject, or intentionally. Hopefully neither and its not lossy only recorded with equipment capable of giving such a spectral analysis
Heres a frequency analysis pic which indicates it not lossy I would say
But then what would the reasons for such blocky spectral analysis be?

another spectral and frequncy of a different song same recording

unfortunately i cant in contact these days with either the original taper nor the person aiding him in the transfer so i dont have any more details beyond the master reel>1st gen reel>digital lineage

Looks OK to me.
Not lossy, anyway.

Looks like it was recorded with a mic with an upper end spec of 18K. Everything above 18K just seems to be noise.

What's the music sound like?

Now I recognize that SA pic in the first post. It appears whoever did the transfer, transferred it to Mini Disc. There is a great example in the lossy or lossless forum under the MD sticky .... Lossy in a sense but not as bad as eMPty3. Here is the sample http://www.thetradersden.org/forums/attachment.php?attachmentid=5861&d=1122376654 If i'm wrong on this one I will eat my boot and take a :nuts:

I think it's OK but hard to tell from these pics. I'd need a video, or a 10-15 sec audio sample.
