This is from Mike Dunn at NEC, if you have access to the NEC forums you can find the original post there


If you need to know about cooledit here it is.

Here you go. If you want it you can download CoolEdit at
Adobe - Soundbooth CS3, Audio Editing Software

The format that the Dialogic card uses is mono 4bit/6khz ADPCM. Cool
Edit will convert to this format. Here's the recipe...

1.) Open audio file

2.) In the menu bar choose "convert sample type" from the edit menu >

3.) Choose 6khz/16bit/mono and then click okay.

4.) Then do a "save as" and in the lower part of the dialog window,
select Dialogic ADPCM (.vox)

I have found that Cool Edit displays 4bit/6khz ADPCM files as
6000/16bit/mono even though they are the aformentioned format. Not to
worry.

ADPCM stands for Adaptive Differential Pulse Code Modulation.

Also, anytime you want to listen to the Dialogic format in Cool Edit > you must add a .vox suffix to the file or it won't play back!
