Be clear, be short:
You can hear some captures made with Sn0ffer (there is low frequencies, so use hearphones or a good sound-system):
This is what it looks like (v0.2):
I play Sn0ffer during some 'Orchestre Philarmonique du /tmp/lab' sets (v0.5):
As you can see, there are 3 Perl scripts, one for UDP packets, one for TCP packets and the last one for Layer 2 frames (Ethernet). You need to install several Perl Libs to use this sniffers, you can use CPAN for that:
root@sn0ffer# cpan -i Net::PcapUtils NetPacket::Ethernet NetPacket::IP NetPacket::UDP NetPacket::TCP IO::Socket::INET
To execute this scripts you need a root/admin access to the machine, 'cause you will use network interface with the promiscuous option (to read all packets, not only yours).
Use the -i switch to specify the interface you want to listen.
For using PureData you have to download the Extended version there http://puredata.info/downloads/pd-extended.
You can record (.wav) your capture, use the PD's edit mode, change the name of the capture (bottom right of the patch), switch to PD's play mode, click on the name then 'start'.
Come out and play:
