Harmonia is a portable application, meaning no installation is necessary. Simply run Harmonia.exe from the extracted ZIP-file.

Note: for audio normalization, MP3Gain is used. You need to have MP3Gain installed, or you can manually set the location of the mp3gain.exe executable. Download and install MP3Gain from its official website. If MP3Gain is not installed or the executable cannot be located, audio normalization will be skipped. You will receive a notification beforehand.

1. Start Harmonia.
2. Harmonia is now monitoring your clipboard. Simply copy a valid YouTube URL (Ctrl + C).
3. The video will show up in the grid. Artist and title will be suggested. You can change these if you like.
4. Repeat for multiple videos if desired.
5. Start downloading and converting by selecting Start all.
6. Once downloads are activated, you can keep adding new YouTube videos. At any time, hit Start all again to also start downloading the new videos. Completed and running downloads will be ignored.

List of settings:
