Any idea what is causing these strange bit scope patterns?

I am getting ready to do some mastering for a client.

These are two bit scope images from the same song but mixed at two different times. It is the same place on both songs.

The person mixing is an 30+ year experienced mixer and is using Samplitude Pro X4. I have worked with him on similar projects in the past and he always does GREAT work.

I have never seen a bit scope pattern like the one shown on the left.

We have been collaborating via the internet for the past three weeks.

He sends me a file and it is good then he remixes the files and they have strange bit scope patterns.

Any ideas?? Some of the bit scope patterns look like they are being "filled in" and not real music/sound. The one on the left is the most current mix and the one on the right is a mix he did the middle of April.

Suggestions and/or comments???

Thanks!

That's weird.

Maybe he's put different plugin(s) on his 2 bus with faulty dithering?

What’s the bit depth of the files he’s sending you? Unless they’re 64bit, the crud you’re seeing above 24bit wouldn’t be written in the file, correct?

What does Schwa’s Bitscope show?

Supposedly 24 bit at 44.1 I will download the additional plug-in and see.

Off topic:

BTW I worked with Xenakis while I worked at the local college as Director of Audio Services. Somewhat of a "strange" person. Very demanding but talented. I worked with him twice. We could not provide the DBSPL he required for his pieces and he became very frustrated. Today it would probably be no problem but when I worked with him all we had were four ALTEC A-7 Voice of the Theater speakers and some Carver Amps. FWIW

I’m sorry I didn’t make your acquaintance when I was doing interviews back in 2009-14. I spent a bit of time trying to contact folks at Oberlin, but had little success.

IX’s time in the US was certainly a strange story, a lot of it located in the Midwest. I had for a long time wanted to write a book about the sixties, and his exploits were the perfect frame for that. Long live those Altecs!
