Hi all,
i own a SB audigy 1 model end the kx drivers..
i have plugged into external box otpical IN a MD and i wish to record digitally
from the MD into my pc without resampling, like copying an esact audio copy bit to bit.
How can i do that ?
(i tried wiht the microsoft drivers, but ihad to set the record level..and itsabsurd in the digital domain)

thanks for your help

bye,
Jack.

None of the present drivers allow to record from digital inputs with "bit-to-bit" precision... (although such ability is present in Audigy hardware)...

Will you think future kx drivers will support this feature ?

>> None of the present drivers allow to record from digital inputs with "bit-to-bit" precision

the 3532a and 3532b releases support this feature, however, it is documented only in our SDK (v3532 - not yet released) and cannot be used without special tweaks

if you wish to perform a bit-to-bit recording of your spdif-in signal (the only one choice currently available), do the following:
run from the command-line: kxctrl -shw 11 81
this will switch the recording to 'bit-to-bit'
now, start the recording via your audio application (note that only 16bit/48000/stereo format is supported)

after you finish with recording, don't forget to run 'kxctrl -shw 11 0' or 'kxctrl -shw 11 1', depending on whether you use 'ac-3 spdif decoding' feature

note that the b2b recording is supported for WinMM and DirectX, not ASIO...

/Eugene

p.s.
this interface might change in the final release of 3532 driver
