<p class=MsoNormal style='margin-left:65.2pt'><span class=GramE><font size=3

<br>
I am capturing 16 bit mono sound samples using some Win32 API function calls.
These function calls return the sound samples in an array of characters. </span></font></span>My
assumption is that this array of characters represents pairs of bytes that make
up a short integer. <br>
<br>
I'm using the following code to convert the samples:<br>
<br>
LPTSTR <span class=GramE>*lpSaveBuffer;<br>
......<br>
for(</span>j=0;j<nBytes;++J) <br>
{<br>
BYTE a = lpSaveBuffer[2*j]; //
left byte<br>
BYTE b = lpSaveBuffer[2*j + 1]; // right byte <br>
short sample = (a << 8) | (b &
0xff);<br>
}<br>
<br>
I'm getting garbage as a result of this conversion. Any help would be
appreciated.<o:p></o:p></p>
