TUNING KEYBOARD v6.7
Challenge
this song's ending sounds a bit strange...
note: insert brackets as appropriate, there is no other punctuation
File given: ttyut-iiiuy+12.wav, a recording of a song played on a keyboard.
Approach
In the metadata it gives you gameID:5593470048. When you go into the game and play you realize that the notes in the filename correspond to the notes of the song. It's only the end of the song when they start playing seemingly random notes.
Solution
Play the same notes the audio file has, work out which on-screen key each note corresponds to on that keyboard layout, and read the sequence of keys off as letters.
