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.

All, I want is a review of a sound card that does realtime SPDIF DTS/DD encoding not just a card that only does it in DVD's. You find one and I'm gonna go buy it.leliel - Friday, February 4, 2005 - link
i'm still using philips seismic edges (philips tbird avenger chipset, PSC705 model) in my boxen because creative can't put out a decent product. i wouldn't mind seeing the new ultimate edge (PSC724) or aurilium (PSC8xx) reviewed. happy with what i have except the latest drivers for these things are about three years old and games like WoW and republic commando aren't happy with them =PEddNog - Friday, February 4, 2005 - link
MrMarbles; check out the card I have, Echo Audio Mia MIDI. Its sample rate is completely controllable, including full lock to 44.1, with zero resample as long as you bypass Kmixer by either using any of the time critical transports (for example, kernel streaming) or even a special proprietary Kmixer bypass for regular wave audio output that's included in the drivers called Purewave. When I bought it, you could find the card for just $200, and it was over a year ago.-Ed

I'm interested in buying a soundcard for playing back highquality (if you can call MP3's that) MP3 files. I got an Audigy2 now. Very happy with the low distortion, has a very clean sound on my B&W Nautilus 805 speakers. But, they also have a very wellknown problem with 44.1khz 16bit stereo playback. So looking to upgrade. I'm a bit of a audiophile, but I can't spend too much. Gaming is not something do a lot of anymore.Pandamonium - Friday, February 4, 2005 - link

THANK YOU, seeing audio on the front page again is AWESOME.LocutusX - Thursday, February 3, 2005 - link
Oh, and the ALC850 is pretty horrible. I used a TB Santa Cruz from 2001 to 2004 (3 years) and noticed the difference straight away when I switched to the on-board sound on my new Athlon64 rig.Later, when I bought an Audigy 2 ZS for Xmas, I noticed the difference on that the moment I popped the card in. Nah, don't waste your time on an ALC850 when there are more worthy things to review;
- VIA Envy24HT cards
- the various Audiophile-ish stuff already mentioned

From what I've read @ Hydrogenaudio, it's impossible to "bypass" the resample stage with an Audigy 2 ZS (when dealing with 44.1KHz source).Someone posted a wave file which contained a particular sine wave. When played back on hardware which could natively handle 44.1KHz, it sounds fine.
When played back on hardware which resamples 44.1KHz to 48KHz, lots of weird distortion could be heard - sirens, alien noises, etc. On the Audigy 2 ZS, even if you used ASIO or Kernel Streaming output, this behaviour was observed. Only when you did a high quality (SSRC) resample to 48KHz did it sound fine.
BTW I don't see the point in reviewing the TB Santa Cruz. While a good card for its time, that was more than 2 years ago. It's been EOL (end of life) for 2 years now, and there won't be any new drivers made for it. It won't work in future OS's (XP64) and even the most recent XP32 drivers had issues with various games.

Question for Derek, why was Audigy 4 judged better than the Audigy 2? It costs more and was just as bad (or worse)as the Audigy 2 in the objective tests.Regarding the audiophile incursion into Anandtech - just please beware that Audiophilia nervosa is contageous...
...when you start hearing differences between $40 and $4000 cables, power cords, volume knobs (yes, knobs, not pots), 'demagnetised' CDs, etc... take a long holiday.

#58, PrinceGaz,Thanks for the feedback. We will explore some of these options.
We did, however, use RightMark 3DSound for our CPU Utilization tests. :-) There wasn't much more detail we could have gone into. We could have reported standard deviation for CPU usage, or even shown the graph over time for each card (which looked roughly the same in every case). The only test we really didn't include there was a test of the maximum number of audio channels on each card, though 32 happened to also be the max channels for the Realtek solution (64 channels for soundblaster 128 channels for gina3g).
There's not much more information that RightMark 3DSound provides than what we showed. Unelss there's something specific you would like us to explore with the program? The effect of custom audio files?
