Title: Connect DAB-tuner with my PC with optical cable
Post by: Filharmoniker on May 04, 2007, 08:33:25 AM

Hello,
I have a DAB -tuner, which has an optical out. My computer has an optical in on the Abit Motherboard.

I have a cable to connect them. The aim is to make .wav files from the tuner. If I connect the tuner it plays back correctly on the PC, so I suppose the signal is recongnised. When I try to record it with Sound Forge, he gives a very streange signal. Instead of waves, like with any normal sound, I have 'cubical' waves, with rectangular edges...The amplitude of these 'cubes' is very small, so very less music is heared. It is possible though to recognise in some way the music, though with a very weak and deformed signal. It looks like something is wrong with the software or something: the signal is wrong captured or wrongly set from digital to analoge.
If I do the same with the normal analoge RCA connectors I have the same problem (the playback is OK though...). I remeber that on my previous PC, the analoge signal was recorded very wel bij Sound Forge. At that time I didn't had an optical connection.

Do I have to change settings in Sound Forge or are there more easy programs to wrok with, or is there a conversion program (read: free ware ;-) )to do this work? Oh yes, I only have Sound Forge v4.5  :-\ That's maybe 8 years old...

You could have a look at Audacity - it's a free audio recorder/editor.

Maybe this might help you set your recording program:

I don't know if you need to make your sound forge kbps setting the same as your DAB station.

powermonkey, thx a lot man!!
After maybe 15 minutes I could solve the problem. The program is easy in use. i don 't know if it's better than Sound Forge just to edit music, but for the recording it is MUCH more sophisticated. I could simply chooce between line-in, SP/DIF etc...
And... now it also works for the analoge recording. I think there was a problem with Sound Forge recording settings for that...
They also have the program in Dutch, that's crazy 8)
Again, Thx al lot all of you!!
