SP/DIF recording on Audigy Platinum 2 ?

[Frederick Smith]

Hi there ...



I am having a bit a bit of a problem recording digital audio with my
Soundblaster Audigy Platinum 2.



I connect the digital co-ax output from either a CD player or DVD player to
the input at on the front panel, and I can hear the audio through the
headphone monitor - so the signal is getting to the soundcard OK. But if I
try to record it, I get either a low frequency "motor boat" sound, or
nothing at all.



Also ... when recording from a digital input like this, what am I supposed
to do select as a sampling frequency ? - Surely the bit rate and sample
sizes are dependent on the incoming signal ?



Has anybody managed to have any success with this - or have I just got a
duff card ?







Regards





Frederick

Recording 16 binary digit/band limited CD audio through the clumsy
SP/dif and in real time too, when ripping a whole CD to HD as a WAV
or CDa can be done in a few minutes at most?
I can only assume you may have a copy protected CD which restricted
you from ripping direct - maybe one of Sony's rootkit CD;s or some
form of DRM, whatever, if you couldn't rip to HD, the very same copy
protection is preventing you from copying via the digital interface.

It could be that he simply hasn't selected the correct default device in
the "Sound recording" section in "Sounds and Audio Properties" in Windows
Control Panel. But then, what do I know?

OK ... if it was copy protected media, would I still be able to hear it
through the monitor ?

Long term, if I manage to get it working, I was hoping to record audio
material from either a freeview box, or from a DAB receiver - the CD audio
excursion is just to see if I can get the recorder to work.

The SB card IS the default device - there is no other audio device

Yup, but you'll have to choose either the analogue or digital input as
record input.

This is a red herring. DRM and the like are not the same thing as copy
protection that can be applied to S/PDIF.

On my mAudio card, you can select S/PDIF as a seperate input or select it
in the sound card's own software. I'm not familiar with the sound card
you're using, but I'm sure there must be a setting somewhere. At the
moment is sounds as though the computer is simply listening to the wrong
input when trying to record. You could also try the settings in the
software you're using to try to record. Obviously the S/PDIF input is
working as you say you can monitor it.

Hi Frederick

I dont have a Soundblaster Card, but I think I read somewhere a while
ago, that you need to select 'Record what you hear' in the control
Panel, or something like that. Certainly SB cards are not great.

I've recorded from a Sky+ to an SB Audigy via an optical SPDIF connection
and it worked fine. There are two "Windows Mixer" control panels. One is the
"Playback" panel which includes "sliders" for each of the enabled sound
sources with a tickbox mute option on each, the other is the "record" panel
which includes sliders for each of the enabled sources and a tick-box to
select the source. One of those sliders is called "What-U-Hear" or somesuch
phrase, but if recording from SPDIF it's better to select the SPDIF input
direct.

You can select "What You Hear" if that's what you want to record. You
can select other things as well. See what choices you have. (Note
that this is in the soundcard's control utility, not in Cubase).
There's another possibility - that the card shows in Cubase as two
separate input devices, Soundblaster Analogue and Soundblaster SPDIF.
You'd have to choose the right one when defining an input in Cubase.
You know how to do that?

One of those approaches will work, assuming your card isn't broken.
And it doesn't sound as if it is - the digital signal is getting in
and being turned into analogue for the monitor output, it's just
Cubase that can't "hear" it.

I agree, Soundblasters aren't great. But yours will do this simple
job OK. The trouble is, people who know enough to troubleshoot your
problem aren't likely to be Soundblaster owners :-)

What input are you recording?

44.1 Khz.

Nobody much uses this method to transcribe a CD to a PC any more.

They use proper digital transfer software like CDEX or EAC - both of which
are free downloads.

The only reason I can think of to go the way you're going is if the CD has
some kind of copy protection on it.
