Sound Source Submission Guide for High-Quality Service

• The sound sources you previously submitted as mp3 files are gradually being phased out of the music market, and current domestic and international music services are providing services in high-quality file formats.
  For smooth service in Korea (Melon, Genie, FLO, etc.) and overseas (iTunes, Spotify, etc.), sound sources submitted in formats such as mp3 need to be replaced with "high-quality specifications (WAV files)".
• In particular, it has been confirmed that a significant number of sound sources registered with the association before 2019 were not submitted as high-quality files.
  If your registered sound source is an mp3, please check and submit a replacement sound source.
