the amplitude is adjusted to signal some specified aspect of the process.

Changed metadata print option to accept general urls
...
This is an - once again - updated patch, that uses avio_write instead
of avio_puts to stream clean text output without null characters. Works
now for me as intended.
Changes metadata filter to accept general urls as file argument without
breaking former behaviour. As a byproduct, it also allows for writing to
file "-" if specified as "file:-".
Example:
ffmpeg -i test.wav -filter_complex "silencedetect=n=-40dB:d=0.1,ametadata=mode=print:file='pipe\:4'" -f null

libavfilter/af_hdcd.c: Collect HDCD stats and report

The new HDCD filter really does nothing to show that it is working or

patch collects information about the decode, like which features were
used, and reports it to the user at the end.
Also,
* Fixes low-level gain adjustment
