Convert WAV to 8 bit, 8 KHz u-Law format

So you have a wonderful new recording you would like to upload to Cisco UCCX (or IPCC, Unity Connection, Unity Express, or whatever) and know that it needs to be in a 8bit, 8KHz, u-Law format.

How do you convert it?

In Windows XP, the Sound Recorder application would allow you to simply change the format by opening it, choosing to save it and then selecting Change in the dialog box. The correct format there is Format: CCITT u-Law and Attributes: 8.000 khz, 8 Bit, Mono.


Now that Microsoft has apparently sucked the life out of Sound Recorder in Windows 7, my next preference is using Audacity.

Edited 7/15/2013: You can find my new post regarding using using the old XP version of Sound Recorder on Windows 7 here: http://webmaxtor.blogspot.com/2013/07/convert-wav-to-8-bit-8-khz-u-law-format.html

The problem now is it's not very clear how to choose the same options.

In Audacity with your file open, confirm the project rate is 8000 (shown in lower left corner of progress bar).

Then, choose Edit | Preferences | File Formats.

In the Uncompressed Export Format, choose Other...

Then, in Header, choose WAV (Microsoft) and in Encoding, choose U-Law.

Then, choose File | Export as WAV and simply name it appropriately.

TaDa.
