Structs

Args 🔒

Functions

command

The clap definition behind --help, for man pages.

execute 🔒

fmt_fixed 🔒

%10.2f on a value that may be infinite — Python prints -inf.

Peak, RMS and quietest-500ms-window for one file.

round2 🔒

Python’s round(x, 2): round-half-to-even on the decimal value.

run
