Software for E100 Karaoke

The iRiver Caption Editor allows to edit or to create new lyrics files (.snc) for MP3. It is a program for creating SNC lyrics files (manually synchronized with MP3 songs). Adding SNC to MP3 with iRiver Caption Editor doesn't work for E100. The program can only be used for manual synchronization of the song text with mp3, and creating new SNC files.

The iRiver LDB Manager allows to find files with lyrics automatically from the internet database, and then add karaoke text into MP3. This software also allows to add lyrics from SNC file into MP3 file (previously created with iRiver Caption Editor) that is viewable on E100.
