Thanks leiff, most think not explained right. I wanted to have the same PC that estah MPX-tool installed a plate to the capture of FM, and not use the Tunne.
It would be a sign of the capture of video and FM, installed on the PC that the MPX-TOOL and then use it to capture this card FM signal to the investment of having to have a tuner.
Flay, it’s possible that this would work, but there’s no guarantee that the tuner on a capture card is good for analysis, and you’d certainly have to modify it to get MPX out (and you’d still need a 192 kHz capture card to digitize the signal).
A capture card is virtually guaranteed NOT to have MPX output, but to have the stereo decoding on-board and feed it to the computer only as a standard L/R signal.
