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.

Control-c ?

Comment by DavieBaby 75 weeks 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.

Comment by unixmonkey3883 66 weeks and 5 days ago

That is freaking awesome.

Any hint to make this work on Leopard ?

Comment by sitaktif 61 weeks and 1 day ago

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

Comment by fastrack20 60 weeks and 6 days ago

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

Comment by foremire 48 weeks and 5 days ago

Has anyone found a solution in 10.5/6?

Comment by megrimm 29 weeks ago

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

Comment by Meeko 28 weeks and 1 day 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 :-/.
