[asterisk-users] Pops & clicks at the end of sound files

[Skyler]

Hi,

 I had a similar issue converting wav files one time. Ended up using sox to
convert to .sln as that ended up being the sounding conversion.

 I used the below command on a directory of files to convert:

for a in *.wav; do  sox "$a" -t raw -r 8000 -s -w -c 1 `echo $a|sed
"s/.wav/.sln/"` resample -ql; done

Hi all, 

We recently decided to get a professionally recorded set of prompts for
our asterisk based IVRs and received these as the following: 

Bit Rate: 1536Kbps
Sample Size: 16bit
Channels: Stereo
Sample Rate: 48kHz
Format: PCM

I use Wavepad to convert it to:
Bit Rate:64Kbps
Sample Size: 8bit
Channels: Mono
Sample Rate: 48kHZ
Format: CCIT-ALAW

I copied these files to an asterisk server and then used asterisk -rx to
convert the files to g729. 

The problem I have is that at the end of every file there is a pop /
distortion after playback. 

Anyone have the same issue before?
