Installation

Windows: Unzip and place the folder anywhere. Run Akorin.exe to start Akorin.
Mac: (Current app bundle is bugged. Releases will return when this is resolved, but mac users will have to build from source in the meantime.)

Building from source

Windows, Mac, and Linux

Prerequisites

• .NET 5.0
• BASS

Steps

1. Add the appropriate BASS library file to the Akorin folder
2. Run dotnet build in the Akorin folder

Usage

Recording

The currently selected line and its note are displayed at the top of the window. You can edit the note to add things like pronunciation guides, and it will autosave with your project.
Press R once to start recording, and press R again to stop recording. The waveform will appear after recording is stopped.
Press space once to start playback, and press space again to stop playing.
Click on items in the list or use arrow keys to navigate through the list. Audio is automatically saved to your specified folder when moving through the list. Lines that are already recorded will be highlighted. When you open a project, it'll automatically jump to the last line you selected.

Changing reclist and folder

Go to Settings > List and folder.

The currently supported formats are:

• Akorin recording list (.arl)
• OREMO-comment.txt
• index.csv for ARPAsing and oto generator
• WavConfigTool reclist (.reclist)
• Plain text reclist (.txt) (Can split lines by all whitespace or by new line only)
• UTAU sequence text (.ust)
• Create reclist from files in folder

When you load or create a reclist, you can export it as an ARL to use again later. The exported ARL will include all of the notes you've added to the current project.

Writing an Akorin Recording List

Akorin Recording Lists use YAML, which is very simple to read and write. Create a plain text file using a text editor like Notepad or TextEdit, with the following formatting.

line 1: note 1
line 2: note 2
line 3: note 3

Save the file with the extension .arl. You can refer to the reclists included in the releases for examples of a full reclist. If Akorin has trouble reading the reclist, try surrounding the line or note with double quotes "like this".
