The project to run NeLSound on top of Microsoft's new XAudio2 API is already nearing it's final stages of development. The driver currently implements all basic functionality required by NeLSound, as well as the some of the environment effects (commonly known as EAX), and has support for the OGG Vorbis music format. I am currently working on adding support for the ADPCM sample buffer format used by NeL to the driver, and I will soon work on the rest of the environment effects implementation as well. Also, the new owners of NeL have made available a new official website for NeL over at, and you can browse the code of the new sound driver at
