Hi, all. I'm developing an APO for Windows Vista that will do some
channel conversion in the LFX. For example, if you're playing a stereo
MP3 or WMA file in Windows Media Player, and the system is in 8-channel
speaker mode, I want the LFX to be in control of how the channel
conversion happens. However, using Vista Beta 2, I'm having trouble
setting the input format the way I want. I'm playing a 44.1 kHz MP3 or
WMA file in Windows Media Player, and I'm on a system where the audio
hardware is locked to 48 kHz. In IsInputFormatSupported(), I can see
how Windows is trying to open the LFX. Since the system is in 8-channel
mode, the output format is always 8 channels at 48 kHz to match the
hardware. However, looking at the input format, Windows either wants me
to sample-rate-convert the audio from 44.1 kHz to 48 kHz while allowing
me to do the channel conversion, or Windows does the
sample-rate-conversion and channel conversion for me before getting to
my LFX. Why isn't there a 3rd option - let Windows do the
sample-rate-conversion, and let my LFX do the channel conversion?
Anyone have any info on this?
