Is it possible to send and recieve audio signal with AI / AO in NI-6229 which is DAQ board.

I'd like to test MP3 Player.

The procedure is below.

1. Send a audio signal of 1kHz from mp3 file in PC through AO in NI-6229.

2. Record it with MP3 player.

3. Play a recorded audio signal with MP3 player.

4. Recieve the signal through AI in NI-6229 and measure frequency and voltage of the signal.

5. Compare the signal with original signal.

Do you think it is possible?

Hello Blue Sky80,

It is possible to measure audio signals using LabVIEW and Sound an Vibration toolset.  Please take a look at this Developer Zone article on Audio measurements using LabVIEW to get more information on this subject.

I hope this helps!
