Wave file format (PCM)
00 DWORD "RIFF"
04 DWORD Filesize-8
08 DWORD "WAVE"
0C DWORD "fmt "
10 DWORD 0x10
14 WORD 1
16 WORD NumChannels
18 DWORD SampleRate
1C DWORD ByteRate=SampleRate*NumChannels*BitsPerSample/8
20 WORD BlockAlign=NumChannels*BitsPerSample/8
22 WORD BitsPerSample
24 DWORD "data"
28 DWORD DataSize=FileSize-0x2C
2C Data goes here

Channels are mixed, eg at 16 bits per sample:

01E0A3F01310E410

Would actually be:

Left Channel: Sample1(E001), Sample2(3101)
Right Channel: Sample1(F0A3), Sample2(10E4)

That pretty much sums it up, thanks to http://ccrma.stanford.edu/courses/422/projects/WaveFormat/ for the explanation, it's better described there, this is just a basic reference chart.
