mp3name.fish - Rename audio files from ID3 tags. Accepts a glob as input e.g. > mp3name **.mp3 and requires ffprobe and mutagen to run (both brewable iirc)

function mp3name --description 'Rename mp3 from tags'

	if test (count $argv) = 0
		echo 'No files provided, exiting'
		return 1
	end

	for file_name in $argv

	    mid3iconv -e UTF-8 $file_name
		ffprobe -show_entries format_tags=album,artist,title -of default=noprint_wrappers=1:nokey=0 -hide_banner -loglevel warning $file_name | read -z result

		if test -z "$result"
			echo "ffprobe failed for $file_name, skipping"

		set title (echo $result | grep 'title' | sed -e 's/TAG:title=//' | sed -e 's/\// /')
		set artist (echo $result | grep 'artist' | sed -e 's/TAG:artist=//' | sed -e 's/\// /')

mp320.fish - Convert flac to mp3 320 CBR. Accepts a glob as input as above. Requires mutagen and sox to run (again, both brewable iirc)

function mp320 --description 'Convert file to mp3'

	if test (count $argv) = 0
		echo 'No files provided, exiting'
		return 1
	end

	for file_name in $argv
		set file_title (string split -r -m1 . "$file_name")[1]

		sox "$file_name" -C 320 "$file_title.mp3"
		mid3iconv -e UTF-8 "$file_title.mp3"

		if test $status -eq 0
			rm "$file_name"
			echo "$file_title.mp3"
			continue
		end
		echo "Unable to process $file_name"
	end
