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>/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>
