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

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?
