Choosing a labeler

Many behaviors of vLabeler depend on customizable labelers. A labeler defines how vLabeler reads, displays, and writes a certain type of label files. When creating a project, you first need to choose the labeler that matches your target software. See Labelers for more details about the concept.

Currently, the followings are provided as built-in labelers:

Working on UTAU oto.ini

For UTAU oto editing, there are two items in the built-in labeler list:

• UTAU oto labeler

  If you only want to edit one oto.ini file, please use this labeler.

• UTAU singer labeler

  If you want to edit multiple oto.ini files under a singer voicebank, please use this labeler. Please set the singer's root folder (which usually contains a character.txt file) as the Sample Directory when you create the project.

Working on audio labels

For label files used in NNSVS/ENUNU and similar systems, the following options are available now:

• Sinsy lab labeler

  This labeler is for Sinsy (NNSVS/ENUNU) lab files, which uses 100ns as the time unit and use (space) as the separator. It only accepts one label file per project. A wav file is bound to the label file by the file name, e.g., if the input label file is foo.lab, the wav file named foo.wav will be selected from the Sample Directory.

• Audacity labeler

  This labeler is for Labels file created by Audacity, which uses s as the time unit and use \t (tab) as the separator. It only accepts one label file per project. A wav file is bound to the label file by the file name, e.g., if the input label file is foo.txt, the wav file named foo.wav will be selected from the Sample Directory.

• NNSVS singer labeler

  This labeler is basically the same with the Sinsy lab labeler, but it can handle multiple label files. Typically, if you have the following file structures:

  - singer
      - wav
        - 1.wav
        - 2.wav
      - lab
        - 1.lab
        - 2.lab

  you can create a project containing all the label files by setting Sample Directory to the singer folder. You can change the wav and lab folder names in the labeler's settings.
