Combining Individual Sounds - Urgent

[JDCAce]

All right, I don't usually do this, but I've come for you for homework help. I have an assignment due tomorrow, and I can't figure out what's wrong with my program. I'm not asking for an answer -- I don't want to cheat -- I just need a little guidance.

The assignment is to create a "sentence" of Sound objects, each sound being one word. I have the algorithm, but I'm just not coding it right, apparently. First I load the three audio files of the three words I want to make the sentence out of: "always," "and," and "around." I'm looping through each SoundSample in the first word and copying them into a newly created empty Sound object, and I do the same for each word, but my output is simply the first word (with a lot of silence afterward).

I can't figure out why the other two words aren't being copied. Could someone help? My code is below. It uses an outside library (including Sound, SoundSample created by the course creators; I believe my program should be readable without me having to post the separate classes.

      {
        // Set the value in the sentence to the value in the word

I have no idea since I'm not familiar with the Sound class. Question though, why do you make the wordSamples array but don't use it?

[JDCAce]

Ah! I think I found the error! You're right, I'm not using wordSamples. I think I need to put it in the inside loop. I'll test around and post back soon. Thanks!

[JDCAce]

Yes! I got it! Thanks for your help!

I'm not sure what I did, but I'm glad to help. :)
