I am just in the process of putting a system together for uncompressed video capture from VCR (using all in wonder 9800). In terms of capturing the sound with the video I wondered what the best option would be?

1) My motherboard is the Asrock ALiveDual-eSATA2 which uses the C-Media CM6501 Audio Codec with UAA architecture. The motherboard has a CD header directly on it so I could connect the All in wonder card with a CD cable directly to the board and use onboard sound for capture.

2) Use a sound blaster audigy 2 zs which I currently already have, however this card is much older than the motherboard so would it really be much better than using onboard sound in option 1?

3) Use a sound blaster x-fi fatal1ty which seems to be a step up from the audigy 2 zs, however how beneficial would it be compared to onboard sound in option 1?

4) Use an M-Audio Delta Audiophile 2496. From forum reviews it seems this is a highly rated card and provides a great balance between cost and performance. While the SoundBlaster cards are often referred to as gaming cards the M audio seems to have the edge in terms of professional sound recording. The problem is the card does not have any headers on it to accept a CD cable from the All in wonder card. I know I could just bypass the All in wonder card and go from the VCR for audio directly into the soundcard, however I have read a few posts saying it is better to pass audio through the All in Wonder card to help reduce sync problems.

I would be really interested to see what people recommend. Not really worried about expense (within reason) as I just want to get the best results I can.

Thanks Dave

On-board C-Media audio tends to be horrible, and won't maintain a clock sync. Don't use it. When using the audio card with capturing video, always use a quality dedicated PCI audio card. (This obviously excludes situations where the audio is hardware encoded with the video.)

Sound Blaster Audigy is fine. Note that the oldest/first Audigy cards had problems, circa 2002-2004.

There's no reason to believe the Sound Blaster X-Fi Fatal1ty will have better audio quality. When it comes to audio cards, the only "better" stuff on the card are the surround-sound features, multiple I/O, etc -- in other words, things that do not matter for the purpose of capturing video. In fact, sometimes these extra whizbang features inhibit proper audio capturing, or cooperation with video capture cards!

M-Audio Delta Audiophile 2496 is probably a fine card, purely from the point-of-view of audio playback, but again there's no real advantage between it and the Sound Blaster card for capturing HiFi audio from a VCR.

Unlike a lot of the other hardware aspects of capturing video, the audio card itself is either (1) working, or (2) not working. The "quality" of the card isn't really a concern. The main issue to look for in audio cards is how much the gain may be badly boosted, or if the clock will not sync properly, but that's generally an issue only found in the cheap chipsets integrated into motherboards. You're not going to face that issue with a name-brand PCI card from Creative Sound Blaster, Turtle Beach, M-Audio, or others. Even off-brand PCI audio cards tend to be passable.

A bigger concern is speaker quality. Far too many people use cheap/junky consumer-grade speakers, which heavily distorts the sound, and have an atrocious frequency response curve.

Are any of these two sound cards any decent for capturing audio?
https://articulo.mercadolibre.com.ar...igy-sb0570-_JM
https://articulo.mercadolibre.com.ar...o-audigy-2-_JM

If so, which one would you recommend?
Mind one come with Installation CD and the other doesn't.

What about this one?

Not the USB item. I've never come across a decent USB audio card.

Audigy cards sometimes had issues, with the biggest problem being distortion and tinny quality. SoundBlaster cards just really were not very good, and many times even the modern onboard Realtek can sound better.

This review from 4 years ago provides some good food for thought.
https://www.tomshardware.com/reviews...o,3733-19.html

In the 1980s and 1990s there were major differences in quality among sound cards and motherboard sound capabilities. The PC inside is a electrically noisy place, and how well the cards and on board circuitry dealt with that was a big issue. There was a lot of bad stuff for sale, and not just the cheap stuff. At that time names like M-Audio, Ensoniq, and Turtle Beach were tops, and Sound Blaster was in the process of dragging itself out of the mud to become decent. (Still good names for legacy PCs.)

Today things are much better, to the point that the market for separate sound cards is all but dead except for folks setting up digital audio works stations and audiophiles with deep pockets (often using USB audio interfaces). The benefit of the USB audio interfaces for modern PCs is they save a scarce slot, provide many I/O options, get the ansdlog audio gear out of the noisy PC case, and reduce the chance of becoming obsolete as the PC bus changes every couple years.

But simple, cheap USB devices are not the stuff audio workstations would use. I would look to brands such as TASCAM and M-Audio as a starting point for USB audio interfaces..

I used Pro Audio Spectrum/Studio cards back then.

Asrock ALiveDual-eSATA2
btw. the specs of this moterboard still refer to Windows Vista, and Windows XP
CPU 2 core is also dated.
A new OS will not like it, and need more resources.
on top of that the soundcard will use many interrupts, which is also bad, maybe even sync issues.
