[michbudz]

Hello,

I would like to record data from speaker (without microphone of course). I mean , read this data which are input to speaker.

This are my mixers and lines:

What kind of speaker do you have?
Most that I know of are output only devices.
Microphones are input devices.

Well, if you yell into a loadspeaker from close by it does work as if it were a microphone. ;-)

Learn something new every day. Something about coils and magnets I suspect.

Yep, loudspeakers and microphones are similar, just like a dynamo, it can act like a motor.

I scaned my friend's computer ( he has sound Blaster Live , I have embabed sound card) and he has something like that :

mixer : Port SB Live! Wave Device, version 5.10 - line : What U Hear source port

I suspect that this is what I'm looking for.
I will get some external sound card , then try again.

My speakers are the output type of course :) I wanna catch stream which is directed to speakers :)
I will share the results soon,
