Automatisch Lieder-Erkennen

Ich digitalisiere gerade meine Kassettensammlung. Da hilft es, sich das aufwändige Titeleingeben zu automatisieren.

Voila: mein Lieder-Erkenn-Skript (basierend auf songrec)

Setup: Install gem „zaru“ first!

require 'zaru'

TIMEOUT = 12 #seconds

semaphore =
rename_jobs = []
threads = []

# setup parallel threads to recognize songs - only for not renamed files
files = Dir["**/*"].select{|e|[".flac",".opus",".wav",".ogg",".mp3",".aac"].include?(File.extname(e).downcase)} # only audio files
files.each_with_index do |f, i|  
  rename_jobs << []
  threads << do
    new_name = File.dirname(f)+"/"
    new_name = File.join(File.dirname(f), $1) if f =~ /^([abcd]?\d+)/i
    new_name = File.join(File.dirname(f), $1) if f =~ /^(track\s*\d+)/i
    name = `songrec recognize \"#{f}\"`.strip
    new_name += " - #{Zaru.sanitize!(name)}#{File.extname(f)}"
    semaphore.synchronize { rename_jobs[i] = [f
