output your microphone to a remote computer's 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.

Control-c ?

then cat /bin/bash > /dev/dsp which takes each byte and interprets it as a frequency (number of waves per second, HZ) and the sound driver plays it.

Would be sweet if i knew how to make this work for Leopard. Any thoughts?

Leopard does not use /dev/dsp, so there should be some alternatives to it

Mac OS X uses coreaudio to input and output sound. No UNIX sound device drivers are present, and, in fact, they are frowned upon by Apple as primitive and ugly. Thus, they will probably never be added to Mac OS X :-/.

Since /dev/dsp is obsolete & missing from Ubuntu, what was that command to wrap those old programs to use PulseAudio instead?

for ubuntu i use this one "arecord -f dat | ssh -C user@host aplay -f dat" (replace the 'dat' with 'cd' to get 44100hz instead of 48000 quality is very good but not so heavy on the bandwidth)

@member1936 : Hi, i tried but couldn't do the same between my two Macs with sox. I succeeded on playing a local wav file to distant speakers but when I try default input and output I have this : FAIL formats: can't determine type of `-' Any advice, clue or idea ? Thanks a lot.

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
