Hi Camclone!
It possible to do the 67 kHz subcarrier with a 192 kHz sound card. However, the 92 kHz subcarrier is too high frequency for 192 kHz sampled audio.
I could possibly add support in a future advanced version 🙂. Would be neat indeed.
It’s not currently possible to run SCAs through the RDS input though — the input is *very* sharply filtered, and only allows 54 through 60 kHz to pass (plus the pilot).
It is however be possible to run Breakaway Broadcast into an external stereo generator software and yield good results — but you’d have to have another program generate the SCAs as well.
Best,
///Leif
