Clicking/popping between sounds

After creating an AGI script to answer calls and placing our ulaw files in place, we can get the system to answer and step through a call flow… however, between each sound file there is a clicking or popping sound that makes it very annoying to listen to the ivr.

I’ve tried using sox to change the format several times and to normalize the volume, but to no avail, it still clicks between sounds.

Is there some setting I’m missing or some filter i need to apply to the sounds to stop the popping?

Thanks.

if you send me one of your audio files i’ll take a look at it… it’s probably something in the file itself as opposed to a problem with asterisk.

PM me for email.

thanks,

I resampled the files using the -2 parameter to sox and it seems to have cleared up the issue.

Thanks.
