Prepping Song Files

Audacity​

  1. Open Audacity and drag in the song you are going to chart.

  2. We will generate 4 seconds of silence at the start of the song. This is to allow players some time to preapare and not isntantly have to start playing.

    • Silence option is located at "Generate>Silence..."

  3. Well use TuneBat to find out the bpm of the song. Just upload the original song file (not the one being edited in audaticy) and it will provide you the BPM and the key of the song.

  4. Back to Audacity, select the silence track you made and go to Change Tempo, located at "Effect> Pitch and Tempo> Change Tempo..."

    • When the menu opens, change the Beats per minute to whatever the BPM of your song is.
    • You are editing the "to" value

  5. Highlight/Select the empty space in front of the Song Track and then generate silence in there.

  • No changes to the length of the silence, use the number it generates. That is the length of the selection made

  1. Delete the Silence track that was made and export the song as "Original.ogg" ("ctrl+shift+e" is export)
