But there is no such thing as "live access." Everything on ASR is open to anyone without registration. Nothing here requires login, etc.
To put this to rest, I asked ChatGPT: "Do you have live access to audio science review?"
This is its response:
I
do not have direct, live access to Audio Science Review’s internal database or a live subscription-style connection where I can instantly pull up pages behind logins or crawl the site as a browser would.
However:

I
can search the web in real time for publicly indexable content from Audio Science Review — including forum threads, measurements, summaries, and posts where they’re accessible without logging in.

If you want something specific from the
ASR thread you linked — for example:
- the measurements Amir posted
- the summary of his conclusions
- or how the 490 Pro scored relative to specific targets
Just tell me what you want and I’ll search for it and summarize or quote it with citations.

That is as mixed of an answer as it could give. Regardless, it says it can pull up threads, measurements and summaries and posts. There is nothing else to be had. And hence, nothing is unavailable to AI users.
