Sound details.
----------------------------------------------------------------------
The sound was recorded during a few minutes of quiet heavy rains and
occasional thunders.  The sound starts off with 1,2 seconds of rain.
Then there is a thunder break lasting for about 2,2 seconds.  The
thunder rolls off into the rain for about 5,6 seconds.  Within these
last seconds you can also hear a faint squeekin' from a door (to the
left in the stereo field).  This is the wind that audio-fies it's
presence via an open door.  (This also helps me identify the sound as
mine......)

Recording and processing details.
----------------------------------------------------------------------
This sound was captured with a Sony ECM-979 MS stereo condenser
microphone and recorded directly onto a Sony TCD-D3 portable DAT
recorder.  It was later transferred digitally to an Akai S-1100
equipped with a digital I/O board, and finally to the Amiga via MIDI
sample dump in Samplitude Professional.  Within Samplitude Professional
I decided to increase the overall level digitally since the recording
level was set not to overload in case of really close thunders.  I used
the fade function in Samplitude Professional to increase the level.
Since the recording was done on a DAT, the sampling rate was quiet
high; 48kHz.  I decided to lower this rate to half the speed before I
converted the sound to 8bits.  Now the sound has a frequency of 24.131
Hz.  This was done in order to save space but still keep up with the
high sound quality from the original 16 bit file.  This also ensures
that the soundfile is compatible with Amiga 8bit sound software.  (Many
8bit programs have problems with *VERY* high playback rates.) Please
beware that Samplitude Professional exports IFF sound with a default
volume setting of 0 (zero).  I haven't changed this.
