Continuous Recording

Hi All,

I am working on an audio logger for a University radio station.  The
idea is to log all data to disk, 24/7/365 without interruption.  What
I am finding is that to record 1s of audio, it takes 1s of waiting,
plus a small additional bit of time to copy that audio into userspace,
about 1.8 ms on the system I am using.  Therefore, in a day, I can not
record a full day of audio.   I am not using the MMAP functions, which
I suppose might reduce that delay, if it is mostly caused by copying
the data.  Does that sounds like a solution, or am I missing something
obvious?  Or, if I am reinventing the wheel, does anyone know of a
readymade open source program for 24/7/365 logging?

Thanks,

Robin.
