Uploading New Audio Files for Announcement Tones
The base stations allows you to upload short audio files so you can
customize announcement tones on your system.
To upload an audio file directly from you PC to the base station, follow:
Configure > Base station > Announcement Tones.
Base stations come with audio files that provide a safe set of announce-
ment tones. You can use factory provided audio files or you may create
customized audio files based on organizational/user requirements.
Creating a New
Audio File
You can create your own audio file using audio software such as ‘Audacity’
and ‘Ocenaudio’. When creating and exporting a new audio file, ensure the
following audio file format and properties are correct for the base station:
■
Encoding is U-Law companding
■
Sample rate is 8000Hz
■
8-bits per sample
■
Channel is mono
■
File length is no more than 64 KB
To ensure you can quickly identify a tone, Tait recommends naming
audio files according to their characteristics. Generic names can cause
confusion.
At least 100ms of silence should precede the tone if the call initiator
wishes to hear it when releasing PTT. This will allow the transmitting
radio to become a receiver again.
Audio File Upload
Prior to uploading an audio file, follow: Tools > Files > Configuration >
Backup to retain a copy of the current audio files.
After you have chosen the announcement tone you want to replace, click
Upload and select your replacement audio file.
