Set WAV Format

Overview

The Set WAV Format tool allows you to convert all the standing greetings and voice names on a Unity server to a selected WAV codec. You can choose from G.711 uLaw, G.711 aLaw or G.729a.

If a site has selected to change recording formats from 711 (default) to 729a for instance, you may want to use this tool to convert all standing greetings and voice names into 729a. While Unity will convert from 711 to 729a (and vice versa) on the fly using software, this does require some CPU cycles and it’s often desirable to try and have all WAV files in the same format to prevent this.

Requirements/Special Notes

Set WAV File Format will only run on a server with Unity 3.1(1) or later installed on it. Simply run Setup.exe and go. No reboot is required

If you want to set all WAV files to G.729a you need to be sure you’ve installed the G.729a codec on the local Unity server.

This tool does NOT convert standing messages in subscriber’s mailboxes.

NOTE: Converting WAV files from 711 to 729 and back to 711 etc… will degrade sound quality since the formats are compressed differently and you lose a certain amount of info during the conversion. Be sure to backup your original greetings and voice names before modifying them (see below).

NOTE: Since this tool interacts with WAV drivers it will not run properly via Windows Terminal Services. A check is made at startup and if it’s in a WTS session it will exit.

Using Set WAV Format

Before setting the volume level, close the SA. It may cache a greeting or voice name in memory via the Media Master control and closing the SA will ensure it releases them.

It is strongly recommended that you backup your greetings and voice names before changing their format. If the WAV files are damaged or don’t sound good you can then recover some or all of them. The Set WAV Format tool has a built in backup and restore mechanism for all greetings and voice names. Simply select a directory to copy greetings to using the “browse…” button and check the “Save original files to” option. Before modifying the WAV Files, the tool will copy all greetings and voice names to the target directory. To restore these greetings, select the “Restore backed up greetings and voice names” option from the File menu.

By default when you run Set WAV Format it selects all voice names and greeting files in the system and pre selects G.711 uLaw as the default. If this is acceptable, simply hit the “set WAV Format” button and watch the progress bar go. When the progress bar completes you will see an animation and a note indicating the SQL database is synchronizing with the directory. Since subscriber and distribution list voice names are stored in the directory itself as well as locally on the Unity server’s hard drive, it’s necessary to force them into the directory. Depending on the number of subscribers and public distribution lists, this may take a while.

When the SQL synchronization process is complete a message box will pop up indicating the application is finished.

NOTE: There is no problem with setting a WAV file to a codec it’s already recorded in, this will cause no harm.

Choosing a Language Interface

This tool comes with built in support for several languages including US English, French, German and Japanese. By default it will display the language the Windows operating system is set for. If that language is not supported it will default to US English.

To manually force the tool to show a different language than the default, you can select the Help | About menu option and click the “Change Language” hyperlink on the About box. The languages installed will be presented in a drop down list and the display will update into that language immediately when you select it.

NOTE: If you select Japanese as a display language and you are not running on a version of Windows that has the Japanese code page installed, the display will show all “?” characters. This is expected.
