audio recorded is broken

[tulkas85]

Hi,

I'm working on a windows application that make sounds recognition from rtsp audio streams, using libvlc and smem.
Audio source is a simple mic plug into an audio module like AXIS P8221.

In my local network all works fine, but in a more complex network I have that audio recorded sounds very bad, audio seems broken.

Can you please listen these audio chunks and tell me what's happen ? https://clyp.it/bp1l3lpv

If I connect using vlc application for windows the audio is good.

Could be a network problem ? Packet loss ?

The only thing I can do now is to change transport protocol and set to tcp, now is udp.
