Audio Quality: Qualitative Analysis
For our qualitative audio analysis, we would like to stress again that listening to analog outputs on PC audio cards is a very subjective and difficult task. Digital should be used where possible, but the majority of people still run analog. And so the quality of analog output is still of the utmost importance.
-- 16-bit/44.1kHz/2-Channel Test: The Mangroves Live at Tir na Nog
This recording was done using a DigiDesign ProTools LE Digi 002 setup on a G5 at a local bar in Raleigh. Though the 1 room + 2 vox + 5 instrument mic setup (for a three piece indi/rock band) left a little to be desired, and the mix down was less than stellar, this gig makes an excellent test track. On the Gina3G and Intel solutions, it's easy to separate the noise and the music, but on the Audigy 2, the audience sounded a little smashed into the band. This problem wasn't as bad on the Audigy 4, but the crowd noise on the other cards seemed a little less muddy and thick. It's likely that any 44.1kHz audio source with a lot of high end will produce a muddled low end on Audigy cards because of the poor IMD at high frequencies. Just because we can't hear the high fequencies that are interfering doesn't mean that we can't hear the product of their interferance.
-- 24-bit/96kHz/6-Channel Test: Creative Labs Demo DVD-Audio
It was hard to decide on what media to choose, so we just pulled a track that we liked from the Creative sample disk. We went with Mannheim Steamroller - Leonardo from their American Gramaphone album. The track fits their normal eclectic style and mixes intricate rhythms with walking melodies. The synth harpsichord on drums is quite interesting. We used PowerDVD to play back the DVD-Audio on all 4 cards, and didn't have any problems. The voicing was clear all around, and try as we might, we couldn't discern one card from another. If we really cranked the volume to painful levels, we could hear some noise on the Intel solution. Unfortunately, there is no way to play DVD-Audio out over a digital connection to a receiver. This makes the analog signal quality of the card of the highest importance if DVD-Audio listening is going to be performed on the PC.
-- DVD-Video Tests: The Matrix / Dream Theatre Live at Budokan
We wanted to test a movie and a live audio performance with our DVD test. The Matrix is always fun to watch, so we just couldn't help popping that one in. And who's better live than Dream Theater? OK, so that may be totally subjective, but they at least create a lot of sound, and being a drummer, it's hard not to want to sit and listen to Mike Portnoy for multiple hours. Both The Matrix and Dream Theater Live at Budokan took full advantage of our 5.1 surround system, though we preferred listening to Dream Theatre using the higher quality headphones in stereo while watching. And so, we listened both ways on each card just to cover the bases.
And what do you know, but we just couldn't find favor with any of these cards. Each did as good of a job as the last playing back these higher quality audio streams.
The only discernable differences in our listening tests came in at 16-bit/44.1kHz on the Audigy series of cards. Tying it back to RMAA, we can point to the poor IMD performance. On a design level, some sites point out that this problem could stem from the fact that the creative DSP is locked at 16-bit/48kHz, and 44.1 is not an even multiple of 48 (as 96 and 192 are). This odd multiple resampling could be causing the issues, but that seems likely only if the DSP were enabled (some EAX/EQ/filtering turned on). In our RMAA tests and during playback, we made sure to disable these features, so this shouldn't have been a factor.
It is possible to have your favorite media player upsample your 44.1kHz media up to 48kHz, which would cause less problems than forcing a native 48kHz device to operate at 44.1kHz. Check the help files for resampling options.

Pleas Do not review audio cards here,your knowledge of the subject is highly limited,
your testing methods with adapters for christ sake are more then questionable,
your pairing of pro audio cards with "demands" like EAX are laughable ,
and it all leads to one thing - Confusing Buyers,
Please stop this nonsense.
Stick to something you DO have a clue about.

so..., where's the roundup?I'd like to see these cards (compared to those already in the article):
envy24 (terratec DMX xfire 24/96)
envy24ht (terratec aureon universe, audiotrak prodigy 7.1, m-audio revolution 7.1)
realtek alc850 onboard
nvidia nf2 soundstorm
turtle beach santa cruz?
lynx, emu, motu and digi002 is also a good addition
by the way, i read somewhere that revolution 5.1 has better DAC than revo 7.1. is that true?

That should be "head-related *transfer* function" (HRTF), not "head-related transform function". The transfer function of a signal-transferring system is the reaction of the system's output signal to an impulse input signal.S0me1X - Saturday, February 5, 2005 - link
#83For the pure digital out card, go with AV710 because it can be flashed with Prodigy 7.1 firmware. Then you can install Prodigy 7.1 drivers (which are much better than Via's OEM drivers). This gives bit-perfect digital out for only $25.
Note that the AV710 only supports digital out via Toslink. So if your receiver does not accept toslink, then EMU0404 is the only choice.

The AV710 has decent 2 channel analog out (in high res mode), but the EMU0404/1212 better.

Disdain for 2 channel?I actually mentioned that I prefered listening to the dream theatre dvd in 2 channel ... i prefer all music listening in 2 channel actually ...
There are not many good 2 channel 24/192kHz DVD-Audio offerings out there ... does anyone have any good suggestions? Most of the stuff I like is mixed into 6 channel. Which just feels wrong for anything but techno or orchestral stuff that tries to put you at the prime listening point of a music hall or something.
Also, note I used rather nice 2 channel headphones while the sonic quality of my surround solution was no where near as good. It was more to test compatibility.
We are certainly open to suggestions on what and how to test to better suit our readers though :-)

#70 - S0me1XThanks for the comment on what I should use. I thought I should clarify. I need two seperate PC's (HTPC's) one is for my room and needs analog out. The other is for a the lounge room and will use digital out into an Onkyo 701 reciever.
What cards should I use for this?
#80.
Correct I would like to see the reviews a little more accomodating to 2 channel audio. All CD's are stereo and they are still the dominant format.

Everyone's asking for so many things to be reviewed. It makes more sense IMO to do a general article on how to get good sound from a PC. Something for beginners, like the excellent articles on taking pictures which have appeared recently. PC audio is really quite simple; but you won't know how it works without digging for information.Gooberslot - Saturday, February 5, 2005 - link
I'd like to see the AV-710 and the Revo 5.1 reviewed. That emu 0404 doesn't look too bad either.I do wish the reviewer didn't have such disdain for 2.x solutions. Not everyone has room or money for a surround sound system.

For those of you with Audigy 2's who want to get the highest quality possible from 44.1KHz sources - you don't necessarily need to spend the $$$ buying a new sound card.Instead, configure either Foobar or Winamp to resample to 48KHz in the output plugin. Both have versions of the high quality "SSRC" plugin available. For Winamp, you need to search for DirectSound 2.0 with SSRC output plugin. There is also an ASIO plugin with built-in SSRC resampling. The results of ABX double-blind tests seem to suggest that going this route is an effective substitution for one of the better Non-Resampling cards...
