# Programming Embedded Music on Hold

## Overview

Embedded Music on Hold is provided by an audio file downloaded to the controller. The audio file must be in the following format:

- Audio type: Microsoft Windows WAV (.wav)

- Audio format: CCITT u-Law or A-Law 8.000 kHz, 8 Bit, Mono

- See System Audio Source Update for the maximum size of the audio files.

TIP: When extracting a file from a CD (for example, from your corporate Music on Hold CD) using a "CD ripper" application, choose a sampling rate as close as possible to 8 kHz. This helps to prevent audio distortion introduced when converting a WAV file from a high sampling rate to a low sampling rate.

When an audio file is downloaded, its audio amplitude is normalized by the controller to ensure uniform sound level and compliance with telecommunications regulations.

You can download audio files to a single controller using the System Audio Files Update form, or to multiple nodes using MiVoice Enterprise Manager (see your Mitel dealer for information on Enterprise Manager).
