[CLAM] There may be a bug in "audio.cxx"

[Neediss Gu]

line 163:
//////////////////////////
if(endIndex>=GetSize())
 {
  TSize ending=endIndex-GetSize();
  memset(chunk.GetBuffer().GetPtr()+GetSize()-beginIndex
,0,ending*sizeof(TData));
  endIndex=GetSize();
 }

nBytesToCopy=(endIndex-beginIndex+1)*sizeof(double);
//////////////////////////
Maybe it should be changed to the following

if(endIndex>=GetSize())
 {
  TSize ending=endIndex-GetSize()+1;
  memset(chunk.GetBuffer().GetPtr()+GetSize()-beginIndex
+offset,0,ending*sizeof(TData));
  endIndex=GetSize();
 }

and  : size=endIndex-beginIndex; -> size=endIndex-beginIndex+1.
