Generating telephony audio prompts with Audacity on Windows and Mac

Using Audacity to generated CCITT u-law prompts on Windows and Mac.

This blog post should be pretty basic, but in the last few months I've had two different parties ask me about this so I figured I would capture this for posterity. If you want to use Audacity to convert your audio file to a compatible format that can play in your Cisco UCCX or CCE call center or any system that uses CCITT u-Law 8.000 Khz, 8 Bit, Mono format.
Assuming you're running the latest version of Audacity (I'm using version 3.1.3 on both Windows and Mac). Open the audio file you wish to convert. There are 3 settings you must change.

  • The format needs to be set to PCM 16-bit.
  • Project Rate (Hz) needs to be set to 8000.

That's it, you're good to go.
