The cwenc utility is primarily a tool for musicians working with Cakewalk music production software, such as Home Studio and Sonar. cwenc enables you to export your original music to a compressed audio file format, such as MP3 or Ogg Vorbis, from within the mentioned Cakewalk products. cwenc is a direct replacement for the time-limited demo-version of Cakewalk’s commercial MP3 encoder program, which is packaged with both Home Studio and Sonar.
