how can I to play the Output file after decoded using ilbc codec?

Hi All: I have compiled the source codes from rfc3951, which is the iLBC's ansi-C implementation, and in which there's one test program. After I complied them, I got this test program( in my project, it's "ilbc.exe"). According to the help information through "typing ilbc.exe" under console window. Yes, I have one .wav file recorded as its input file, its mode is 20( means 20ms), its encoded file is encoded.stream( this is the file name I called), its decoded file is decoded.stream(also I called). The program run successfully, and I got the files : encoded.stream and decoded.stream, but how can I play out the sound? which players should I use, or some other ways ? Thank you.
