Manage audio files

Message Editor gives you the ability to upload your own audio files and use them in messages to consumers. You also can use the shared audio files managed by Nuance and made available to all clients.

Note: You can create and modify message content in MOD projects only. In standard projects, Nuance creates the message content according to the requirements of the client. To make changes to standard projects, contact your Nuance representative.

Supported audio formats

The Proactive Engagement Platform / supports .wav audio files with the following encodings:

  • 8 bit, 8 KHz, Mulaw encoding, single channel (recommended)

  • 8 bit, 8 KHz, A-law encoding, single channel

  • 16 bit, 8 KHz, linear encoding, single channel

The rate used must match the rate of the current session (8 KHz).
