output your microphone to a remote computer's speaker

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.

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
arecord -f dat | ssh -C user@host aplay -f dat

how do you... un-output it?

Control-c ?

Comment by DavieBaby 264 weeks and 4 days ago

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.

wow, that looks really scary.

Any hint to make this work on Leopard ?

Comment by sitaktif 250 weeks and 5 days ago

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

Comment by fastrack20 250 weeks and 2 days ago

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

Has anyone found a solution in 10.5/6?

Comment by megrimm 218 weeks and 3 days ago

Do it trough SSH and output to your own machine and your a spy :P

Comment by Meeko 217 weeks and 5 days ago

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 :-/.

how did u find it?

Comment by deargodzw 152 weeks ago

That's cool!

Comment by regding 124 weeks and 5 days ago

Since /dev/dsp is obsolete & missing from Ubuntu, what was that command to wrap those old programs to use PulseAudio instead?

Comment by klepsydra 102 weeks and 3 days ago

That is awesome. Pure CommandLineFu!

Comment by thecamelcoder 97 weeks ago

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)
