dynr

A convenience script for managing loudness-related metadata for music files.

Usage

Run in a directory with *.flac files. Assumes the directory is an album.

Supported file formats

Currently only *.flac is supported

Dependencies

  • dr14_tmeter
  • metaflac
  • GNU sleep

Optional dependencies

  • beets — for updating the beets database

Code style

Uses POSIX shell, verified by shellcheck. Most of the heavy lifing is done by the programs, so there's no need for bashisms.

Commands with weakly defined behaviour are avoided, see the spinner function:

spinner() {
	printf "%s" "$1"
	while true
	do
		printf "%s\b" "-"
		sleep 0.1
		printf "%s\b" \\
		sleep 0.1
		printf "%s\b" "|"
		sleep 0.1
		printf "%s\b" "/"
		sleep 0.1
	done
}

No echo!

To do

  • Refactoring
  • Use loudgain
  • Beets integration for optional beet update
