Hi
If you need to view your recordings you need cooledit pro.
If you need to do it your self you need to get the Wave file format which is
very simple:
struct WaveFileHeader
{
unsigned char RIFF[4];
unsigned long waveformSize;
unsigned char WAVE[4];
unsigned char fmt_[4];
unsigned long formatSize;
unsigned short FormatTag;
unsigned short N_Channels;
unsigned long SamplesPerSec;
unsigned long AvgBytePerSec;
unsigned short BlockAlign;
unsigned short BitsPerSample;
unsigned char data[4];
unsigned long waveformDataSize;
};
and lookup Forie transformation (hope the spelling is right) as a starting
point for the algorithem.
