What I'm getting to is why you think you need the SMTK to do the analysis?

Yes, that is my biggest question at the moment, whether I really need it.

And also, yes, the music is supposed to go through the audio cable.

Then start with the introductory courses for LabVIEW and learn LabVIEW in the first step.

The problem is, I still don't know if I need the SMTK for the analysis...

But I do already know the basics of LabVIEW.

And I can't find any help on how to make the audio go through the audio cable, I feel like I searched the whole internet!

Look at the LabVIEW sound pallet vis.  If you play a sound thru the sound card and there's an audio cable plugged in to headphone jack then I think it uses that path as default.  No need to specify it.

When you are talking about issues regarding 'how to make the audio go through the audio cable' are you meaning in terms of:
1. Transmitting the audio from the phone across the cable

or

2. Receiving the data as when it is reaching the computer

Additionally, I would recommend looking at the 'Continuous Sound Input.vi' example in the 2014 example viewer. This should give you a good start on trying to read data from the audio inputs.

Regardless of if you need to use the SMTK or not working through this example and getting it to read data from an audio input will help advance you a significant portion towards your goal.

I mean talking about receiving the data when it reaches the computer, I've been looking but I can't seem to find it

 Start the NI Example Finder (LabVIEW -> Help -> Find Examples) and search for "Sound".

The Sound Functions can be found in the functions palette under "Programming -> Graphics & Sound -> Sound".

Thanks!

I looked at the example programs, and for me, it raised a question;

The examples either say that the input has to come from a microphone attached to the sound card, or a file.

Since I need to transfer the audio file through a cable into the sound card, does it count as a microphone or a sound file (I'd assume as a file, but I always like making sure)?

Thanks for all your help so far (and everyone else's)

That would be a microphone.

The sound card doesn't know and doesn't care what the source of the signal is.  It sees the same thing whether the signal is coming from an actual microphone or some other electrical source.

You have a device that "plays the sound" (say, your phone, a tape player, etc.).  It has an Audio Out jack into which you can plug headphones that have a stereo plug, or into which you can plug an "Audio cable".  As far as your DAQ equipment is concerned, this "system" acts like a microphone -- it makes voltages that vary over time, and if connected to headphones (by being plugged into directly into the headphones) will produce a sound in the headphones.

So plug your Audio cable from your device into the "Audio In" on your DAQ device and you should be good-to-go.

Note -- you shouldn't need to ask such elementary questions!  Be an Engineer/Scientist and experiment, try it out, figure it out for yourself!
