Default Configuration

The default maximum length of audio that Spectrum will play is 30 seconds. In some cases, the play time may need to be expanded beyond this threshold, such as repeating announcements in multiple languages. This article will explain how to change the parameters of the maximum audio length. This can be done from any client machine.

**NOTE: If using "play sound" to play audio to users via the client, these steps will need to be repeated on every client in use.

Changing Max Audio Length

Windows

Open Windows Registry
Navigate to Computer\HKEY_CURRENT_USER\SOFTWARE\Digital Watchdog\Digital Watchdog DW Spectrum Client
In the registry field on the right, right-click an open area and select New > String Value.
A new string value will immediately be created awaiting a value name. Set the value name as maxMp3FileDurationSec. Note that it is case sensitive.
