I would instead just say:
"To enable AEC logging, enable the gyp variable aec_debug_dump=1."

There are multiple ways to enable gyp variables.

Marking parameters const in function declarations is just noise to callers, so
there's little point in doing it. (But not entirely pointless. IIRC, gcc and
clang will let you have the consts in the definition but not in the declaration,
which is what you'd want, but Visual C++ complains about that. Still, they're
not generally worth it.)

In the night sky, stars appear surrounded by empty space on all sides, but
that's just because they're far enough away that the light that you see was
emitted before our style guide went into effect.

Wonderful comment! :-) (and of course you are right, will do the change :-) )

Done!

Why not int? (That's what you always should pick unless you have a good reason.)
