The following command will Output your microphone to a remote computers speaker.
dd if=/dev/dsp | ssh -c arcfour -C username@host dd of=/dev/dsp
This will output the sound from your microphone port to the ssh target computer’s speaker port. The sound quality is very bad, so you will hear a lot of hissing. An alternate version:
arecord -f dat | ssh -C user@host aplay -f dat
You can optimise by replacing the ‘
dat‘ with ‘cd‘ to get 44100hz instead of 48000 quality is very good but not so heavy on the bandwidth. Now don’t blame me for spooking your friend or colleagues by doing this.
