Corporate Plan and higher virtual domain accounts include the
use of the popular RealAudioŽ
server.
STEP 1: CREATE A SOUND FILE
If the sound file that you want to make into a RealAudio file
is already saved on your computer you can skip to step 2.
If you want to create a sound file from an external source
(e.g. your CD player, VCR, or Microphone), you can use a program
called Sound Recorder which comes with Windows95 (usually located
in the Windows directory as "Sndrec32.exe") or you can
download an audio editing program called Cool Edit which is
available in shareware and full release versions. You will need
to consult your sound card manual to learn how to send audio from
your source into the computer.
For best results, encode the audio in the highest possible
setting (16-bit 44.1MHz). Consult the software's documentation to
find out how to make these settings. The RealAudio Encoder will
eventually compress it down, so it is recommended to start with
the highest quality source.
Once you create the sound file, save it as either a .wav, .au,
or .pcm file.
STEP 2: ACQUIRE THE REALAUDIO SOFTWARE
In order to create and listen to RealAudio files, you will
need to download and install the RealAudio Player and RealAudio
Encoder from the RealAudio
web site. RealAudio offers a full version of their software which
affords better quality playback and may include other features.
STEP 3: TURNING YOUR SOUND FILE INTO A REALAUDIO FILE
Follow theses steps to create a RealAudio file:
- Open the RealAudio Encoder program.
- Select the file that you want to encode by hitting the
"Browse" button.
- Select the sound file (e.g. .wav, .au, .pcm).
- Select the desired compression and file name on the right
side of the screen. (e.g. "14.4 Mono",
"28.8 Mono", "28.8 Stereo", and
"ISDN")
- Select START ENCODING from the Encode menu at the top of
the screen.
The original sound file will be scanned and copied to a
compressed format. You have just created an RA file.
** Important **
Do NOT use underscore ("_") characters when naming RA
files as they will not be interpreted correctly by the .ram file.
STEP 4: UPLOAD THE .RA FILE TO YOUR WEB SITE
Upload the .ra file to the root directory of your web site in
binary transfer mode.
STEP 5: CREATING THE .RAM FILE
You need to create a text file with a ".ram"
extension. This text file contains a URL to the realaudio file in
the following format:
pnm://<yourdomain>/~<userid>/audiofilename.ra
Note the "pnm:" prefix. Substitute your domain name
and userid above. There must be a tilde (~) before the userid.
This file can reside in the root directory of your account. The
audio file name must have a ".ra" extension.
Once the .ram text file is created, save it and upload it to
your web site in ASCII transfer mode. We suggest using the same
file naming convention. (e.g. "test.ram" will launch
the "test.ra" file)
STEP 6: CREATING THE HTML CODE FOR THE REAL AUDIO FILE
The HTML document does NOT reference the .ra file itself; it
must call the .ram file which, in turn, launches the RealAudio
file as represented below.
<a
href="http://(yourdomain.com)/(textfile.ram)">Listen
to Audio</a>
If you reference the .ra file directly from your HTML code,
the audio file may play, but you will not benefit from the
streaming audio effect.
STEP 6b: EMBEDDING A REALAUDIO FILE
You will also have the option of embedding a RealAudio file so
that the .ra file will begin playing as soon as the html page
loads. This way, the web visitor will not have to click on a link
to hear your sound file.
To do this, make a copy of your .ram file and resave it as a .rpm
file and upload to the same directory as the .ram .
Then, reference the new .rpm within the page's html like this:
<EMBED SRC="yourfile.rpm" WIDTH=250 HEIGHT=35
CONTROLS=ControlPanel AUTOSTART=TRUE>
