This is the old spectral sound driver for the SoundBlaster 16/32/64 series only.
This code is here for educational purposes only.
Please do NOT use it, since it contains serious bugs.
The most important one is that the FPU context is not saved/restored.
Use the new spectral sound driver working on the top of OSS instead.
For the ALSA version, feel free to contribute.
Thanks.
