hi todd,

thanks for your zip-file. i do really use labvie 7.0. so the arrangement in the vi may work fine. "may" means, i still havent a duplex-soundcard. the ordered one will come in the next view days :-)

the vi shows me two "U8" streams to the in- and output chart. do you think this streams are in phase, are in the same time? I like to compare the output with the recorded input. thats why i have to be sure and carful about the synchronisation.

what was the idea to snake the error-messages throw all the sound-moduls? is it becouse of the error output?

tanks an soon,

stefan

hi todd,

thanks for your infos. i still try to get work my onboard sound-card. the computer is in fact rellly old (pentium III). so, maybe i have to recognise to buy one of this soundcards from creative. there very cheap models.

thanks for your image. do you found the *.vi in the example libary of LabView? may you send me the *.vi or post hier in the forum?

soon,

stefan

thanks todd,

do you know how i can play a sound AND (in the same time) record the played sound over a microphone?

i like to have a synchonisation to calculate the transmission (or the absorbtion of a lot of frequency) in the spectrum.

between the speaker and the microphne is a polymer structre. this soft material with lots of gaps for air let not all frequences pass. so, i will know wich one will be absorbed.

any idea?

thanks,

stefan

If I recall correctly, the examples found by searching the NI Example Finder (under the Help menu) for "sound" were quite useful.

The sound vi's are here:

yes, thanks todd.

now i try to send a sine to the soudblaster. how do i do it, so that i can analyse them in Labview over an Micro at the soundblaster?

soon,

stefan

hi there.

im new in LabVIEW- world. an i try to send soundinfo (sine, or cos or a sound from a wav) direct from LabVIEW to the soundblaster in my PC (Windows!). I like the record with a micro (connected to the soundblaster) the soundwaves an measure the difference in LabVIEW.

So, I like to send sound from LabVIEW and I would analyse there.

Any Ideas?

Witch plugin do I need?

How do I connect du my line-in?

thx,

markus
