Usage: normalize-audio [OPTION]... [FILE]... Normalize volume of multiple WAV or MP3 audio files -a, --amplitude=AMP normalize the volume to the target amplitude AMP [default -12dBFS] -b, --batch batch mode: get average of all levels, and use one adjustment, based on the average level, for all files --clipping turn off limiter; do clipping instead --fractions display levels as fractions of maximum amplitude instead of decibels -g, --gain=ADJ don't compute levels, just apply adjustment ADJ to the files. Use the suffix "dB" to indicate a gain in decibels. -l, --limiter=LEV limit all samples above LEV [default -6dBFS] -m, --mix mix mode: get average of all levels, and normalize volume of each file to the average -n, --no-adjust compute and display the volume adjustment, but don't apply it to any of the files --peak adjust by peak level instead of using loudness analysis -q, --quiet quiet (decrease verbosity to zero) -t, --average-threshold=T when computing average level, ignore any levels more than T decibels from average -T, --adjust-threshold=T don't bother applying any adjustment smaller than T decibels -v, --verbose increase verbosity -w, --output-bitwidth=W force adjusted files to have W-bit samples -V, --version display version information and exit -h, --help display this help and exit Report bugs to <email@example.com>.
