CME BACD Really Doesn’t Need *.au Format Audio Files

I know whoever starts working with CME BACD, specially those voice engineers, starts feeling stress to find the right media encoder to convert media files to *.au format – even I used to feel the same. ๐Ÿ™‚ But really *.au is nothing special! Maybe the *.au extension is just another extension of CCITT u-Law, 8Khz Mono Attribute and 8-Bit encoded files, we are well known of this format used for all Cisco voice applications – in UCCX, UCCE, CVP, CUE etc. etc. Thanks to Mark Snow!

If you have your UCxn ready, or CUE ready, or UCCX ready or even your Windows XP is ready ( ๐Ÿ™‚ ) then you have all to move forward. You can change the string ‘param welcome-prompt’ to ‘param welcome-prompt anything.wav’ and it will work fine. Just make sure the format is as mentioned and the ‘anything.wav’ is in the right folder into the flash.

If you are still using Windows XP then use the default Sound Recorder to convert the prompt from any type. If you are using Windows 7, copy the original Sound Recorder application from Windows XP System32 and paste it anywhere on Windows 7, it will work great even though it might show some warning prior start – just ignore it. ๐Ÿ˜‰

All other prompts except the welcome-prompt, file names must need to be the same. So you still need the *.au converter? Answer is ‘no’ – just rename the prompt from, for example, ‘en_bacd_options_menu.wav’ to ‘’ – it’s a trick!

I hope you won’t google again the ‘*.au media converter’. ๐Ÿ™‚
