Introduction
It's been quite some time since AnandTech has tackled an audio review. With Intel feeding higher bandwidth to onboard solutions and ever more data available to add-in cards through PCI Express, we could start to see some changes in the way that the industry approaches audio. We already have DVD-Audio and SACDs on current storage formats. With HD-DVD or Blu-ray coming down the pipe shortly, we'll have larger storage devices to feed the bandwidth-hungry PCs of today. That means even better quality media.
Our drive in life is to stay ahead of the curve and help as many people understand and ride the wave of upcoming technology as possible. When AnandTech got started, the AMD/Intel war was just getting going and 3D hardware was just beginning to take off. Before the advent of hardware 3D graphics acceleration, the video card was basically used as a rasterizer that drew a 2D image to the screen over an analog output. When talking about image quality, all rested on the DAC, which took the image of the screen in RAM and converted it from a digital grid of color values to an analog signal that the monitor could understand. Back in the day, Matrox started getting fancy and accelerated 2D windows function calls so that the CPU didn't have to draw everything itself. Slowly, more and more drawing was handled by the graphics card until we ended up moving complex 3D functions onto the graphics card and removing overhead from the rest of the system.
Over the years, a much slower trend has been happening on sound cards that parallels the graphics card industry. We have 3D positional audio and hardware DSP effects that manipulate audio in order to make it sound like it's contained in an altogether different environment.
Some of the key factors have kept the audio industry from advancing as fast and furiously as the graphics industry. First, our ears are easier to fool than our eyes. In general, people just don't care as much about hearing things where they are if they can see it. But there are mold breakers. Games like Doom 3, Thief 3, and The Chronicles of Riddick: Escape from Butcher Bay, are aurally quite beautiful and the sound quality not only adds to the experience, but is essential to gameplay as well.
There hasn't been enough emphasis placed on more than a 2-speaker 3D positional audio yet. In our opinion, applying HRTFs (head related transform functions) to 2-speaker setups is on its way out. Solutions like Doom 3's 5.1 channel surround implementation are doable and sound more natural. As the average end user for any given game begins to have a 5.1 surround system rather than a 2 or 2.1 system, we will start to see more and more developers use better sounding techniques.
The minimum quality for PC speakers is way too low. The speaker is the weakest link in the audio chain, and there's no need to buy an expensive sound card if you're going to have a cheap set of speakers connected to it. As people start to understand audio more, they will start to embrace it. The more realistic visuals become in games, the more obvious problems with audio will become. If by no other factor, we will see audio quality improve on the PC.
Today, we are going to take a look at a cross section of the audio industry. The lineup includes two cards from Creative (the Audigy 2 ZS Platinum Pro and Audigy 4 Pro), the Realtek Intel HD Audio solution, and the Echo Audio Gina3G. With these cards, we are covering our bases for the consumer add-in market, professional recording, and onboard audio solutions. Over time, as we review more audio solutions, we will compare against these cards as well.
Before we get to the cards and tests, we will need to take a look at what it is exactly that we will be doing. First, we will look what goes into an audio solution, and then we'll take a look at RightMark Audio Analyzer. As most of our analysis will be based on RMAA, understanding what all its tests mean is of the utmost importance.

For me personally what I would want is reviews of gaming perfomance since I used the SPDIF outputs and my HiFi so they all should so the same. I'd also like to know how much difference there really is between different EAX implementations and if it is true that a new SoundStorm board is coming out. I'm sure you know. Can't you just claim you forgot the NDA? ;)reidc - Thursday, February 3, 2005 - link
My main reason for a soundcard is transferring analog audio from my Turntable(remember those 12" pieces of vinyl????) to CD- or commonly referred to as "needle-drops". The higher quality DAC's and discrete components the better.When I went from my old SB-Live to turtle Beach Santa Cruz- I recevied a huge boost in quality- the drop in noise was huge.
I'd love to see how the TB SC holds up in this regard compared to the listed products.
Oh- my TB SC is currently not in a PC- as I am just getting the Intel 915 board running in a mchine. I assume by seeing the Intel HD Audio tests- I WILL be putting my Santa Cruz in.

Yup, a wider range of cards would be nice.ottodostal - Thursday, February 3, 2005 - link
I am quit disappointed with this review as there are only so few audio cards there. There are so many of them on the market! You must definitely include M-Audio Revolution 7.1, and some card from Audiotrak Maya + Prodigy series (aka Prodigy 7.1), and Aureon 7.1 Universe or DMX 6fire from Terratec. These are of the major cards on the market and there are missing. You could also include Turtle Beach Santa Cruz, and some card from Hercules.I would also include more mid-range and maybe some even some high-en cards (like those from Aardvark or R M E or MOTU ) generally, do not concentrate on low-end cards like Audigy 2 from Creative. In graphic cards reviews you expect us to pay over 600USD for them, so why to concentrate on value cards in audio tests? BTW if you think that people are not doing such things like playing games on audio cards which cost over 800USD you are wrong :)
You should also include some external USB and Firewire cards like Audiophile USB or FireWire 410 from M-Audio (one of my friends recently brought the Audiophile USB replacing some older Audiotrak Maya and he is quit happy with it. He told that even listening to mp3 files is clearly better).
You must also include latency tests in the review and you should comment on support of main standards lide ASIO and GSIF.

#13, ceefka,if you're refering to not calling Intel HD audio, it can do 24-bit/96kHz ... It just can't record at that bit rate. Playback is no problem. Of course, it's not as high quality as we would expect to see from that many bits per sample at that sampling rate.
#12, S0me1X,
The gina3g uses an external DAC/ADC which is one of the reasons we see a cleaner signal. Of course, the soundblaster uses a /better/ DAC, so we see lower noise and dynamic range even though the signal looks a lil shaky at spots.
external DACs are a very good idea.

Any chance for one of the Terratec soundcards? I heard they're pretty good.My ideal soundcard or onboard solution should be
-96KHz/24-bit DTS/Dobly Surround and any previous standard
-optical and coaxial s/pdif input and output
-perhaps an analogue breakoutbox for simple stereo operation and additional analogue outputs.
With so many DVD-players around (even in cars), there is no need to stay in the 44.1/16 realm. 48/24 already sounds so much better than 44.1/16.
It would be nice to have onboards being taken more seriously by the manufacturers. The leads on a mobo are all quite exposed to everything else going on in there. A few efforts in shielding would probably make a real difference, even without changing the chip. I am not ready to pay for a crappy onboard solution. And don't call it HD unless it can do 96/24.

Best way to get quality sound out of a pc is to use an external DAC. I'm using a Benchmark DAC1 that I'm very happy with :)SignalPST - Thursday, February 3, 2005 - link
I just hope that Creative would fix the 44.1kHz resampling issue and IMD problems with the Sound Blaster Zenith sound cards thats suppose to come out sometime this year.sxr7171 - Thursday, February 3, 2005 - link
I don't see how the Audigy 4 is so much better than the Audigy 2 to recommend it over the Audigy 2. They are pretty much the same with the Audigy showing weaknesses and one strength in 24/96 D/A conversion. I guess internal computer audio is still not to be taken very seriously except for games (which the reviews sort of hints at).wrecktangle - Thursday, February 3, 2005 - link
any chance you could take a look at the m-audio revo 5.1? i've been looking for a review of this card for a long time. even a short update/comparison to the revo 7.1 would be great.on the whole, this review seems alright. kinda short though. definitely touch on recording quality in the future. maybe you could also stretch out the qualitative bit with some more music listening tests of other genres.
is it just me, or are the spectrum plots missing?
