SYMPTOMS
When you are recording in the Microsoft Windows XP sound recorder, the sound in the 22 kilohertz (kHz) 8-bit mono mode does not sound the way you expect it to.



CAUSE
This problem occurs if the truncation method is used to translate the 16-bit stream to 8-bit instead of the rounding method. The codec can deliver 16-bit data. If the program is trying to make an 8-bit recording, Kmixer &quot;down-mixes&quot; the 16-bit stream to 8-bit.
