===== FlaCuda =====
~~NOTOC~~ {{ :flacuda.jpg}}
**FlaCuda** is probably a world's first CUDA-enabled FLAC encoder.
It's opensource and licensed under LGPL.
Current version is 0.8, published December 30th 2009.

===== Speed Comparison =====

Compared to reference flac 1.2.1 on Core i7 940, it runs approximately 10 times faster on GeForce GTX 285, when using higher compression ratios (modes -7, -8). FlaCuda -8 is faster than flac -0, and provides better compression than flac -8. Thanks to case@HA for the graph:

On this graph X-axis is compression ratio, Y-axis is encoding speed (vs realtime playback)

===== Requirements =====

It is a .NET application, so you might have to install Microsoft .NET Framework.

===== Command line options =====
  CUETools.FlaCuda.exe [-0..-11] filename.wav [-o filename.flac]
