+This driver uses the Win32 audio system to provide a GAUDIN channel.
+
+It supports 2 channels, Channel 0 being a mono channel and Channel 1 being a stereo channel.
+
+For stereo, the samples are interleaved. Remember to allocate enough space for two samples per
+sample period.
+
+This is a simple driver that makes no changes to the mixer so set up the audio mixer using
+the windows control panel audio mixer (obviously in record mode) before starting recording.
