So the
early outlook is that the Revolution might not be the
perfect gamer's card. The lack of DirectSound hardware
acceleration appears to limit your frame rate to some
degree. But what about music and DVD playback?
What kind of quality can we expect here? We ran
one lest test, using RightMark's Audio Analyzer, and
then went to our ears for the final word.

How does it stack up? |

RightMark Audio Analyzer is an independent audio
measurements open-source project developed by iXBT.com/Digit-Life
team. The test suite performs various tests of
electro-acoustical performance of sound cards and
other real-time audio devices. Testing is
accomplished by playing the test signals and recording
them after they pass through the testing chain.
These tests were performed in loop back mode, where
the same card was used for playback and recording.
We ran two tests at two different bit rates/sampling
rates.
This is where the
Revolution really shows its true colors.
As you can see in the comparisons to the Audigy 2, the
Revolution typically has a lower noise level, a much
better dynamic range, and less crosstalk between the
speakers. This results in a cleaner sound when
listening to music or DVDs. A quick way to check
these results with your ears is to turn up the volume
on your speakers while playing back music. We
didn't hear anything but the music with the Revolution
7.1, but static was noticeable with the Audigy 2.

GAMES:
It was important to find games that truly took
advantage of 3D audio to really make a good decision
here. As we mentioned earlier, Tony Hawk Skater
really doesn't have any advanced audio setup, which
made it a non-choice. We settled on two popular
games, both of which have EAX support; Neverwinter
Nights and Enter the Matrix. We found that we
weren't overly impressed with the sound effects in
Enter the Matrix. Although we did hear sounds
from the rear channels, they were sometimes muddled,
although this could be more of an issue with the game
itself than the Revolution. On the other hand,
Neverwinter Nights, was greatly enhanced by the
surround sound support. An immersive game in its own
right, the proper spatial placement of attacks and
parries made battles seem more realistic. The
soundtrack came through beautifully from the front
channels, with the melodic mix of tracks that NWN is
known for. We didn't notice any playback
problems in either game that could be attributed to
the Revolution, and on higher-end systems the CPU
utilization complaint will most likely by a small
issue.
MUSIC:
We listened to a number of MP3 tracks in WinAMP 3.0,
and CD Audio in Windows Media Player 9, which supports
24bit playback. For the MP3s we tried to find a
good mix of music, choosing tracks from Enya, Pink
Floyd, and White Zombie. We also tossed in a few
CDs by Blues Traveler and Prodigy. It should be noted
that MP3s and CDs are played back in stereo - not
surround sound. We listened using two speakers
and while they sounded fine, it was hard to say that
it truly sounded better than on the Audigy 2. It
was only after enabling the Circle Surround Sound II,
and choosing the 'Music' option, that we were truly
impressed. The upsampling from 2 speakers to 5
speakers plus subwoofer added a new life to anything
we listened to. We cranked up the volume and
then sat back as the room really came alive with
music. I highly suggest to any music lover to
give the CSS II a listen, as it made any track more
symphonic and enveloping. While the Audigy 2
also offers a similar technology, it didn't impress us
the way the Revolution did.
DVD PLAYBACK:
Using the
bundled WinDVD 4.0, we searched through our
collection, and played back a few scenes from Star
Wars Episode II - Attack of the Clones, Lord of the
Rings - Fellowship of the Ring, and Pearl Harbor.
All three of these movies have received commendations
for audio excellence, and the DVDs offered Dolby 5.1
playback. First, a quick switch in the drivers
back to "no processing" was needed. Then, the
correct choice must be made in the audio setup from
the DVD menu. As with games, the 3D placement of
the audio added to the overall impact of the movie.
Nothing was compromised, as the music tracks played
through clearly from the front channels, while the
sounds of battle rang true from the correct location
on screen. Laser shots and flying planes rotated
around our heads from the extra speakers. Once
you have used such a setup, it's near impossible to go
back to a 2 speaker setup.
M-Audio
set out to provide the best audio card on the market
for the right price, and our gut feelings are that
they have done an almost perfect job. From
games, to music, to DVD playback, we were continually
impressed by the sheer quality and liveliness of the
playback. The drivers that we downloaded from
their website were a quick download, and were easy to
use. The only option missing there would have
been the equalizer, but this could easily be fixed in
a later release. CPU utilization was higher than
comparable cards, but this too may be solved with
newer drivers. The audio quality would normally be
found on expensive professional cards, but M-Audio has
made it available to even mainstream consumers,
listing the card at a sub-$100 price point, generally
cheaper the the Audigy 2.
One other
note is that a soundcard is helped or hindered by the
speakers attached to it. Obviously, without a
5.1 or better setup, the Revolution 7.1 isn't able to
live up to it's strengths. True, the sound will
be clear and crisp from two speakers, but it was when
we were able to experience the surround sound
capabilities of the Revolution 7.1 that the card
really put a smile on our faces. In a perfect
world, we might have full DirectSound hardware
support, easy to use drivers, and the best audio
quality out there, but for now we'll settle for two
out of three. The M-Audio Revolution 7.1 audio
card is a great solution for those who want to look
outside the Creative camp, and we give it a
9 on the
HotHardware Heat Meter.
