Rugged Audio Shield for Arduino

Hi All

Recently I bought the Rugged Audio Shield, to combine it with my Arduino UNO.
I would like to load the file "RecordWAV.ino" which I found on

When I try to load the file using the Arduino software, I get a load of errors.

Rec_PlayBack:31: error: 'RAS' does not name a type
Rec_PlayBack.cpp: In function 'void setup()':
Rec_PlayBack:34: error: 'RAS' was not declared in this scope
Rec_PlayBack:43: error: 'SOURCE_MONO' was not declared in this scope
Rec_PlayBack:43: error: 'SOURCE_MIC' was not declared in this scope
Rec_PlayBack.cpp: In function 'void loop()':
Rec_PlayBack:53: error: 'RAS' was not declared in this scope

So I try to load it via the Arduino UNO. But the errors already pop up during compiling.
Do I need other software to load this file?
I feel pretty stupid. What do I do wrong? What should I read?

I don't have a lot of experience with Arduino, but I did make a nice 24Vdc/4KW bidirectional motor controller using a Arduino UNO.
So making a record and playback sampler shouldn't be so difficult I guess....

Any help is appreciated!
Cheer; nico.
