# What is Karedi?
Karedi is a multi-platform editor that lets you conveniently create songs for Ultrastar. "Creating songs" is mapping the vocal track of the song to a format that the game understands.
To adapt a song to Ultrastar, you need to transcribe the vocal line - for every syllable of the song define when it begins and ends and in what pitch it should be sung. Doing it without some editor is practically impossible.
## Why use Karedi?
There are other editors/creators available but Karedi is arguably the most **advanced** one in terms of the features.
It supports **multiple operating systems** ([](https://camo.githubusercontent.com/fc52ed9db6e5a73db0ce9ac31746bd15247ab70cbb66b8e4ac00cc7e58227008/68747470733a2f2f696d672e736869656c64732e696f2f62616467652f57696e646f77732d3030373844363f6c6f676f3d77696e646f7773266c6f676f436f6c6f723d7768697465) [](https://camo.githubusercontent.com/bf78f0ac5a01d1a54bca3773c40e5bf309116d730751758aea1c030a34adbca7/68747470733a2f2f696d672e736869656c64732e696f2f62616467652f4c696e75782d4643433632343f6c6f676f3d6c696e7578266c6f676f436f6c6f723d626c61636b) [](https://camo.githubusercontent.com/f7f88fb073f44d4fe6be93cc12a9bba97cf2cda214bbf64ae95630e3097248d1/68747470733a2f2f696d672e736869656c64732e696f2f62616467652f6d61634f532d3030303030303f6c6f676f3d6170706c65266c6f676f436f6c6f723d7768697465)) and unlike some other editors has convenient installers and **no external dependencies**.
