Release Notes: RealAudio Encoder 3.0 for Windows

Setting RealAudio Encoder Options

Turning the Audio Signal Display On or Off

The RealAudio Encoder displays the audio signal for both the input and output files. Turning off this feature results in somewhat faster Encoding. To turn this option on or off, select or clear the Show Audio Signal in the Options menu.

Play While Encoding

If your PC has sufficient performance, you can listen to the audio as it is encoded.

To hear the audio as it is encoded:

  1. Select Play While Encoding in the Options section.
  2. Choose the Playback Fileter by selecing either Unfiltered to hear the input audio, or Filtered to hear the encoded output.
This option requires substantial extra processing time. If the audio skips or is not available, your PC may not have sufficient performance to play correctly. To help ensure real-time performance, this option is not available for live input streams.

Save Default Settings

To save the current options settings as the default settings that are loaded each time you start the Encoder, choose Save Default Settings from the Options menu. The following settings will be stored:

  1. Title
  2. Author
  3. Copyright
  4. Compression Type
  5. Selective Record
  6. PerfectPlay mode
  7. Show Audio Signal option

Running the Encoder from the Command Line

To automate the encoding of multiple audio files, you can specify command-line arguments that direct the Encoder to process an input file and then shut down. The syntax is:

<encoder executable name> <file to encode> [<settings file>]

Example:
c:\raencode>encoder.exe c:\rafiles\test.wav c:\rafiles\settings.txt

<encoder executable name> Name of the encoder executable.

<file to encode> The digital audio file to encode (See Supported Input File Formats).

<settings file> The name of a settings file. This parameter is optional. (See Settings File Format below.)

Settings File Format

The settings file specifies the compression type and the title, author and copyright strings for the .ra file. This parameter is optional. If not specified, the settings are those most recently stored by the Save Default Settings command.

If a description file is specified, it must be a text file with the following format:

[Default Settings] Title = My Song Author = RealNetworks Copyright = 1996 Codec = DNET Flavor = 3 SelectiveRecord = 1 PerfectPlay = 1

Note The settings file must start with the [Default Settings] line; all other lines are optional. Any option you do not specify in the settings file will be set to the default setting.

Drag & Drop Encoding

The Encoder will automatically launch and encode a .wav, .au, or .pcm file when you drag the file onto the RealAudio Encoder shortcut on the desktop.

The resulting file will have the same name with a .ra extension. It will be saved in the same directory as the input file, and will be encoded according to the last saved default settings.

Changing RealAudio File Description

You can change the Title, Author, or Copyright text, and modify the Selective Record and PerfectPlay settings in a .ra file using several different methods:
MethodDescription
RealAudio EncoderOpen a .ra file, edit the text fields, and click Encode. RealAudio Encoder modifies the fields. The RealAudio Encoder does not re-encode the file, it just modifies the text strings. Note: Turn off the Listen While Encoding option, otherwise, the entire file will be played.

RealAudio Exchange Tool (rax)This is a command line tool available for Windows and Unix.
.ram FileSet the Title, Author, and Copyright text strings in the .ram file.
Events Compiler or Timeline EditorSet the Title, Author, and Copyright text strings in the .rae file using either of these tools.
