Real Audio Configuration
STEP 1 - Creating ContentRealAudio content may be created from previously recorded digital audio files. Prerecorded files may be in .au .wav and .pcm audio formats.
Using the Real Audio Encoder, encode the audio which you want to make available on your site. For compatibility with the largest number of Real Audio players out there and with the largest number of connection types, you should encode the audio in both 14.4K and 28.8K formats. Note that these files will have a .ra extension.
STEP 2 - Creating Metafiles
Metafiles are text files with the extension .ram. Metafiles contain the addresses of the RealAudio (.ra) files. These addresses are in the form of URLs. Instead of pointing to the .ra audio file, your Web page will be set up to point to it's metafile. This metafile, as said before, contains the URL (Uniform Resource Locator) of the audio file (or files) you want associated with the hyperlink. The user's browser passes the URLs to the RealAudio Player, which retrieves .ra files from our RealAudio Server. Simply put, the .ram file is the metafile which points to the.ra file which contains the actual audio data. Is this crystal clear?
The locator type used by RealAudio software is pnm (Progressive Networks Metafile) so addresses you put into a metafile begin with pnm://
To create a metafile:
STEP 3 - The HTML TagIn your HTML document, reference the metafile in a hyperlink as follows:
<A HREF="http://www.asis.com/your_directory /welcome.ram ">Welcome!</A>where welcome.ram is the metafile containing the text:
STEP 4 - Uploading to the ASIS ServerYou'll need to upload your .ra and .ram files to the ASIS server and place them in the directory you serve your web pages from. Be sure to upload the .ra file as binary and .ram as text.
IMPORTANT: Before you can use the Real Audio server, we need to configure it so that it can access your files. Please send email to firstname.lastname@example.org asking us to configure Real Audio support for your Virtual Web Server.
There are many other features of the RealAudio server which you can take advantage of. The content creation guide available from Progressive Networks site (in PDF format) documents all of these features. Some of these include:
