I am trying to Convert the *.rtpdump
file, created by Wireshark into wav file by Sox.
In Wireshark the original file is played without any tatering sound in the audio file, but when I convert it to wav file via SOX (on Windows), there is continuous tatering sound throughout the clip and the actual voice remains in background.
I tried the u-law encoding, a-law and others, the best it can get is with u-law, but it's also not so much audible. I tried the lowpass, gain, treble things but that also is not helping, changing channels, bit rate and other options make it worse. Tried many things but tatering is not going
sox.exe -t raw -r 8000 -e u-law -c 1 66.rtpdump -t wav d:\out.wav -V
sox.exe -t raw -r 8000 -e a-law -c 1 66.rtpdump -t wav d:\out.wav -V
The first few bytes within each packet are causing this tatering sound.
I removed these bytes and the combined all the packets without these bytes to create a tatering free sound.
