General
This document describes Progressive Networks' RealAudio Player.
Our web site is http://www.realaudio.com please check it for the latest
information. Please see http://www.realaudio.com/help.html for help and
more information. The software and documentation is provided to you in
accordance with your license agreement.
The RealAudio Player provides real time sound over the Internet.
Once you have installed the RealAudio Player, RealAudio will play
automatically when you select any RealAudio clip on a World Wide Web page.
You do not need to load the RealAudio player first. The
RealAudio Player only plays RealAudio files. It does not play .au
or .wav files.
To use your RealAudio Player, connect to a World Wide Web site
that has RealAudio. Click on a link and the RealAudio player will open and
start to play. The Player first contacts the host
computer that contains the audio. It then briefly buffers some audio. If
you are curious about the audio packets comming into your computer, please
pull down the "View" menu and select "Statistics."
-------------------------------------------------------------------
Quick Start
Follow these steps to install the RealAudio Player for Windows:
1. Download the file RAWIN100.EXE. You can do this by going to
our home page http://www.realaudio.com and following the
download links.
If your web browser asks "How would you like to handle this
file" choose "Save to Disk.". If you web browser displays
the text of the file instead of downloading it, configure
it to save the MIME type "application-octet-stream".
You can find instructions for configuring your web browser
on our site. Start at http://www.realaudio.com/help.html
and choose FAQ. From the FAQ, choose the "Downloading the
RealAudio Player" entry.
2. Run RAWIN100.EXE.
o From the Program Manager choose File - Run, and Browse
to find where you had your Web Browser save RAWIN100.EXE
OR o You can use the file manager and double-click
on RAWIN100.EXE.
OR o If you have Windows 95 you can choose
Start - Run, and Browse to find the directory where you
had your Web Browser save RAWIN100.EXE
3. Follow the instructions. Use "Express" setup unless you want
to control where and how the player is installed. At the
conclusion of the setup program, the RealAudio player will
launch and play a Welcome to RealAudio message. If this
message sounds distorted, please see the "Sound" section
of these Release Notes.
--------------------------------------------------------------------
System Requirements
Your system needs to have the following in order to
run the RealAudio Player:
* 486/33 SX or better PC running Microsoft Windows 3.1x,
Windows NT or Windows 95
* 8 megabytes RAM.
* 2 megabytes free disk space.
* A sound card with a Windows Sound driver.
(The RealAudio Player is not compatible with the
PC Speaker program or other software programs which
emulations a sound card.)
* An Internet Connection. Either a direct connection
or a 14.4K Baud or better modem with a SLIP or PPP
connection to an Internet Service Provider
-------------------------------------------------------------------
Software Requirements
In order to install the RealAudio Player, you will need
* Microsoft Windows 3.1x, Windows NT or Windows 95
* Standard Sound Drivers for your sound card
* A TCP/IP Protocol Stack (Winsock or equivalent)
In addition, to get the most benefit from the RealAudio Player, we
recommend that you have a World Wide Web browser installed.
-------------------------------------------------------------------
Supported Web Browsers
The following World Wide Web Browsers are currently supported:
* AIR Mosaic (Internet In a Box)
* Booklink InternetWorks (also known as GNNWorks)
* Cello WWW Browser
* CompuServe connection using AIR Mosaic
* EINet WinWeb
* InternetMCI Navigator
* Microsoft Internet Explorer
* NCSA Mosaic
* Netscape Navigator
* Quarterdeck Mosaic
* Spyglass Mosaic and Enhanced Mosaic
If you have a NetCom (version 1.60 or later) account or
an America OnLine(version 2.5 or later) account, you will
need to use a different Web Browser than the Web browsers
supplied with your account. We have tested both of these
connections with Netscape Navigator available from
http://home.netscape.com or ftp://ftp.netscape.com.
To use a third party browser, first establish your network connection
by dialing into NetCom or Ameria Online and logging in.
Once you are connected, minimize the NetCom or America Online
window and start Netscape Navigator. For example, if you were
using NetCom, you would login to NetCom first. Once your connection
has been established, minimize the NetCom window and start Netscape. When
you are done, quit Netscape then quit NetCom. Be sure to run
the RealAudio Installer (RAWIN100.EXE) after you install Netscape
on your system. Otherwise, you will have to manually configure
Netscape.
If you are using IBM's OS/2 Web Explorer then please see our on-line
Configuration Instructions. Go to http://www.realaudio.com/help.html
and choose "FAQ". In the FAQ, choose OS/2 Web Explorer. The
RealAudio Installer does not automatically configure Web Explorer:
you will need to manually install the RealAudio player by following
the instructions on our site.
RealAudio is not supported by
* Lynx
* Chameleon Web Browser (Note that you can use the
Chameleon Stack with an alternate browser.)
* Prodigy dial up Connections
* Pipeline browser
-----------------------------------------------------------------
Accessing RealAudio through Firewalls
RealAudio uses port 7070 for TCP and ports 6970 through 7170
inclusive for UDP transmission. If you are accessing RealAudio
through a firewall, your firewall administrator will need to
authorize these ports. You can point your administrator to our
firewall page, http://www.realaudio.com/firewall.html for details.
--------------------------------------------------------------
Reporting Feedback
We are very interested in your experiences with our products.
Please use the problem reporting form located at
http://www.realaudio.com/problem.html or the copy attached
to the bottom of these release notes to report problems.
If you have comments or suggestions, please e-mail them to
support@realaudio.com .
-------------------------------------------------------------------
Sound
Audio is transmitted to the RealAudio player in the RealAudio
format. The transfer rate for RealAudio is approximately
1 Kilobyte/second. The player then by default produces 16 bit
8 Kilohertz sound. If you hear garbled audio then you can change
the kind of sound the RealAudio player produces. To change the
kind of sound produced, please pull down the "View" menu and
choose "Options". Select "Advanced" and you will see toggle boxes
for "use 8 bit" and "use 11 Khz":
* 16 bit 8 Kilohertz (default)
* 8 bit 8 Kilohertz (select use 8 bit)
* 16 bit 11 Kilohertz (select use 11 Khz)
* 8 bit 11 Kilohertz (select use 8 bit and use 11 Khz)
If you are not receiving AM quality audio, please see our
FAQ entry on audio quality by going to
http://www.realaudio.com/help.html and choose FAQ. From there,
select the "Audio Quality" entry.
---------------------------------------------------------------------
The Internet Adapter (TIA)
The RealAudio Player does not currently work with TIA.
TIA does not transmit UDP packets to client connections.
If you connect using TIA you will receive everything
but the audio. A TIA version that supports UDP is expected later
this year.
---------------------------------------------------------------------
Known Problems
* Having large applications open may prevent the RealAudio
installer from executing. If this happens, please close
all other applications and then install.
* Starting or quitting large applications while playing
RealAudio can cause some brief disruption of the playback.
* Playback on some 486/25 SX computers does not work properly.
* The RealAudio Player is not compatible with Netscape Navigator
1.1 Alpha Release. There are no known compatibility problems
with the Netscape Navigator 1.0, 1.1 or later releases. If you
are experiencing problems with using RealAudio Player
with the 1.1 Alpha version of Netscape, please upgrade to the
1.1n release version.
