str = 
'amjad_alI_khAn\khamAj-4.amjad_alI_khAn.zakir_hussain_and_the_maestros_3.mp3'

new_str = str.gsub("_", " ")
puts new_str

new_str = new_str.gsub(/\w*/) do |match|
  match.capitalize
end
puts new_str

new_str = new_str.gsub("-", " ")
puts new_str

pieces = new_str.split(/\.|\\/)  #split on . or \
p pieces

result1 = pieces[3]
result2 = pieces[1]
result3 = pieces[2]
result4 = pieces[3]
result5 = pieces[4].downcase

puts "#{result1}\\#{result2} - #{result3} (#{result4}).#{result5}"

--output:--

["Amjad Ali Khan", "Khamaj 4", "Amjad Ali Khan", "Zakir Hussain And The 
Maestros 3", "Mp3"]
Zakir Hussain And The Maestros 3\Khamaj 4 - Amjad Ali Khan (Zakir
