Recording line in with Soundforge, and Audiophile 24/96 Options

[evereux]

I'm having a problem recording the output from my CD player through the line in of my soundcard, the Midiman Audiophile (Window's XP).

The problem is distortion. I can't seem to find a way to attenuate the line level input in soundforge and this is causing clipping.

I'm beginning to wonder if this can be removed since during normal playback (through PC) I also get audible clipping, even when the line in is attenuated using Midiman's control panel. I suspect the Midiman doesn't like the output levels of my CD player?

I'm quite sure the input signal itself isn't a problem since playback direct through my amplifier reveals no clipping.

Any ideas?

You can, but you can't get back the part of the analog signal that was to loud.
At least not on my AP2496 card...

Well, routing in my case is as follows (since there is no external mixer available yet, the soundcard itself acts as a mixer) ...

Midi Keyboard I/O <-> Delta AP Midi I/O

Midi Keyboard Line Out -> Delta AP HW In

Delta AP HW Out -> Amplification

If the Keyboard produces an output that is too high, you will hear noticeable clipping artifacts emerging from the Delta AP's ADC ... if I slide back input level (HW In) some 6 dB, everything is fine (Soundforge recordings do not show any clipping artifacts) ...

So I just can't imagine why an analog signal cannot be attenuated to a non-clipping ADC output in that case ... it is just a matter of voltage

EDIT:

My Terratec EWX 2496 allows to adjust the ADC's gain level separately to match your (in this case: low) source voltage without the need of further software normalization (maybe this is what you mean)
