Hello,

Audio input of our Osprey 500DV is Stereo via XLR connectors. Audio Input setup is 44.1 KHz 16 bits Stereo (windows XP host)

But� Audio result on captured video files is mono, (it is actually the left signal that was sent to both side).

On WME, AudioInputMixer setup options are grey, but I can see that the entry line mixing is set at the upper left without being able to change it.

Any Idea ? 

Thanks in Advance,

Rodolphe

When using low bit rate profiles with Windows Media Encoder, the audio is forced to mono. WME9 does this at lower bitrates even if it's a stereo profile.  For example, when streaming at the following bitrates & using a stereo setting, the following results would be achieved:

Bit Rate   Sampling Rate   Result
12Kbps       8 Kbps         &n; bsp;  Left Channel is duplicated
32         &nbs; p;   44         &nbs; p;        Left Channel is duplicated
40         &nbs; p;   32         &nbs; p;        Records left and right (stereo)
48         &nbs; p;   44         &nbs; p;        Records left and right (stereo)
