Can anyone give me a lead for this;

As the audio comes in to drive, the stream itself needs to be encrypted to
be made tamper-proof, not just read-only. If anyone does as much as change a
meta value or cut a sample, it must ring alarm bells. (It's a
security/evidence thing)

I'm not getting far on google with this, have you been here before?

There's really no completely tamperproof solution. Checksums are a reasonable
notion, but may not stand up in court. Ask an evidence attorney.

Might a pair of analogue security copies, made on a verified machine in
parallel with the digital working copy, then immediately placed in a
sealed package, stand up in court?

It worked in the opposite direction on the Watergate tapes, and the
British police use a similar system for both audio and video records of
interviews.
