What You Need to Know About Using Audio
on Your Web Site

Millions of people are listening to audio
on the Web every day. They're not just
teens downloading MP3 audio clips of their
favorite songs, either.
Maybe you're among them. They're people
at home and work listening to on-demand
audio on topics running the gamut from
financial advice to relationships to technology
to entertainment. And yes -- they're even
tuning in to health and wellness topics.
With so many health sites on the Web,
using audio well can set your site apart
from the pack. Audio also can be a powerful
way to attract site visitors and keep
them coming back. It's considered "sticky,"
meaning visitors will come to listen to
your audio and stay around a while. Audio
players are plentiful and best of all
they're usually free to download.
The only way to determine if audio works
for you and your Web site is to get the
creative juices flowing and try it.
Testing 1,2,3 -- How Should We Use Audio?
Your site can feature audio versions
of popular health education articles,
health seminars, news updates, descriptions
of medical procedures, special health
product offers, and patient testimonials.
Adding an audio greeting to site visitors
lends a personal touch to your site and
humanizes the user experience. (For an
idea check out the greeting on the MedRocket
home page at http://www.medrocket.com.)
Audio features are also a good way to
make your site more accessible to visually
impaired web surfers. The possibilities
are almost endless. You can even include
the audio links in email messages.
Delivering the Goods -- Streaming Audio
In the olden days of the Web the quality
of audio was pitiful. It was just barely
passable AM-radio quality. More recently
though, Web visitors can hear very good
quality audio even over relatively slow
Internet connections (28.8 Kbs).
Audio quality isn't the issue that it
once was and the choice of content delivery
now comes in two basic flavors -- streaming
audio and downloadable audio.
As the name implies, streaming audio
sends the audio data from a server to
the user's browser in a more or less continual
stream. This is good because it lets people
listen to the audio as it arrives without
waiting for the entire audio file to download.
Pick Your Favorite Format
In the streaming audio arena, RealPlayer
from RealNetworks claims roughly 90% of
the market. The other common streaming
formats are Windows Media Audio and Shockwave
audio. Recently even MP3 files can be
streamed, which has excellent quality
audio though usually requires higher connection
speeds.
Conversely, downloadable audio usually
requires the entire MP3 or WAV file to
download before it can be played on the
user's computer. The up side of this method
is that the audio can be much higher quality
-- near CD quality, if you will -- than
is possible from streaming media over
a slower Internet connection. It is possible
now to stream MP3 files.
Generally, I recommend using streaming
audio for most uses, unless you want to
provide your Web visitors with a high-quality
audio presentation that they can download
to their computer and listen to at their
leisure without an Internet connection.
MP3 files can also be loaded into portable
digital audio players and some PDAs.
Cue Talent -- Creating Your Audio Content
Once you've decided on the purpose and
focus of your audio content, you're ready
to begin the process of creating a script,
recording, converting to digital format,
and delivering the files.
If you decide to create the audio files
on your own, here's the basic sequence
of events that will take place:
Scripting --
Prepare a script for narration. Unless
you're simply providing a verbatim audio
version of an existing text or HTML document,
you should write the script in a conversational
tone. Remember to write for the ear and
not the eye. Some words and phrases look
fine on paper but sound muddy (even slurred)
when spoken aloud. Read your script aloud
before you have it narrated. Make sure
it sounds natural.
Record the Narration --
You can either record right into the computer
or record to a high-quality analog or
digital recorder and then transfer the
recording to the computer. The two crucial
elements at this stage are the quality
of the narration and the quality of the
microphone.
Professional voice talent knows how to
control their voice and deliver the script
with feeling. You might be able to have
an on-air personality at a local radio
station record the script for you for
a reasonable fee. Otherwise, find someone
with a great voice in your organization
or track down a professional. As for the
microphone, the little one that came with
your computer won't sound nearly as good
as a studio microphone. Use the best microphone
you can find.
Digitize the Audio --
Whether you record the narration directly
into the computer or onto audiotape first,
at some point you'll have to get the audio
into the computer. Most late-model computers
have the capability to digitize audio.
Record the audio at the highest quality
possible; 16-bit audio at 44.1 kHz is
the common setting.
Recording simple sounds on your computer
is fairly simple. However making a good-quality
recording suitable for broadcast on the
Internet is more challenging. The only
way to determine if your equipment and
technique are up to the task is to record
a test and listen to how it sounds streaming
from a server.
Adjust Audio Quality --
Once the audio is on your hard drive you
should open the file in an audio-editing
program like CoolEdit. Check Downloads.com
http://download.cnet.com
for other freeware and shareware packages.
Crop the narration to cut extra silence
at the start and end. Then adjust the
equalization levels (cut 100 Hz and lower
and boost between 1 and 4 Khz). Then normalize
the audio track, which optimizes the loudness
of the recording in relation to the loudest
segment. Other adjustments in compression
and noise reduction can also be made at
this time. Save as a WAV or AIFF audio
file.
Encode the File --
Decide how you'll be delivering the final
audio file. If you are using Real Audio,
then you need to use the Real Encoder
(http://www.real.com) to transform (encode)
your WAV audio file to a Real Audio (RA)
file. For Windows Media Audio, you'll
need to use the Windows Media Encoder
(http://www.windowsmedia.com) to create
a Windows Media Audio (WMA) file.
Upload to the Server --
After you've successfully encoded the
audio, upload it to your Web server using
an FTP program. Depending upon the number
of people who might access your audio
file at a time, you may need to place
your audio files on a special server,
such as a Real Audio server. For testing
however, a basic Web server should work
fine.
Create Links --
Add a link to your test audio file on
a simple test HTML page. Click on the
link and see how it sounds.
Seems like a lot to do, I know. If you
don't feel comfortable with digitizing
audio, resolution, sampling rates, file
format, compression rates, and other nuances
of audio production, don't despair. Let's
look at a few audio production alternatives.
Ready, Roll Tape. -- Your Production
Options
There are several ways to add an audio
health experience to your health site.
You'll need to consider your expertise,
available time, and budget to determine
the best solution for your situation.
They range from a do-it-yourself approach
to total outsourcing to licensing audio
health content. Here's a run-down of some
of the possible solutions.
D.I.Y. (Do It Yourself):
If you, or someone at your organization,
has the necessary skills, your could create,
produce, and deliver the content yourself.
Most marketing teams don't have the resources
available for this route, but it gives
you the greatest control. Recording audio
on your PC has become so easy that it's
worth looking into.
Script and Outsource:
You could develop and script the content
on your own, and then outsource the narration,
recording, audio encoding, and delivery.
This allows you to take advantage of the
writing skills of your marketing staff
and hand off the more technical details
to other professionals. Just remember
that writing for the ear is different
than writing for the eye.
Outsource Everything:
If you're used to working with advertising
and public relations-type agencies, then
you'd probably be comfortable with outsourcing
to an audio house for scripting and creating
professionally produced audio content.
Just be sure your project management expertise
and budget are up to the task.
License Audio Content:
You can also license free or fee-based
audio health content for use on your site.
In many cases the licensing also allows
you to link to the files on the content
provider's site, which saves you from
dealing with most of the technology issues
and allows you to get up and running quickly.
How Are Your Ratings?
Now let's say you've included a few audio
tests on your Web site for a month or
longer. What kind of feedback have you
received? What do your server logs tell
you about the number of hits your audio
features have received? Are more people
bookmarking your site?
If Web visitors liked what they heard,
and your content is fresh and interesting,
they probably bookmarked your site and
will return for another listen -- sort
of like setting their car radio presets
to a favorite station.
You CAN use audio to improve your "ratings"
and keep Web visitors coming back. The
longer they are at your site, the greater
the chance you have of communicating key
messages, selling products, raising awareness,
and pursuing other important marketing
and public relations objectives. Done
well and used creatively, audio could
be another secret weapon in your online
marketing toolbox.
