Harmony Express is a virtual 5.1 sound card. It is as small as a
USB flash storage device with an output port for headphones and
an input port for a microphone. A USB extension cord is also thoughtfully
included in the blister pack. You just need to plug it into a free
USB port and Mac OS will do the rest. You probably need to go to
System Preferences to select the sound output you wish to use.
I listen to music via a
hi-fi stereo set so I cannot give any impressions about headphone
usage. Ditto about the mic input. Compared with the soundcard that
comes with my old Pentium 3, the sound out of my iBook is pretty
good. Harmony Express sounds better though, with better bass to
give a more balanced listening experience.
Miglia offers customised
software/driver for Windows XP (downloadable from their website)
and it gives the option to create a virtual 5.1 output. I don't
have 5.1 speakers so I cannot vouch for this but watching movies
with AC3 5.1 sound out to my 2 speakers, the sound staging is very
good and there is some semblance of surround sound. You probably
need real 5.1 speakers to truly check this out.
When I watched normal movies
(without AC3) I notice a slight echo and I had to de-select the
virtual 3-D option to cut out the echo. This software/driver is
NOT available for the Mac but you still get excellent soundstaging
on it. However with the customised software on XP, there is a discernible
difference.
I have a Chaintech AV710
soundcard (basically a budget soundcard that many people say is
comparable to much more expensive ones for 2-channel stereo output)
and musicwise Harmony Express is either equivalent to or better
than the Chaintech. The Chaintech tends to be a little bright and
hard but I find Harmony Express to be more balanced, with the bass
sounding a little louder. Mid to high tones are quite well defined.
With it's small size and
compatibility with Windows, Mac and Linux, it is hard to beat for
maximum flexibility. I even used it on my old P3 (which I think
has the old USB1 port) and it worked as well. One thing though,
it gets pretty hot.
