Voice Changer Program for the Arduino Problems

So i am totally new to programming but i was able to do this last year for halloween but i don't know how to do it again. I forgot. What i am aiming to do is make a real time voice changer to have a creepy voice for a halloween costume. I already have to arduino shield and all the parts for it and they are working. The problem i am having is trying to get the adruino.ide program to work with my wavehc.h and waveutil.h files. I have the adavoice sketch file but can't get it to verify with those 2 files.

i keep getting an error message of this...

so like i said i am new to programming and i don't really understand exactly what i need to do to get those to verify. If anyone could point me to a tutorial on this or an answer i would greatly appreciate.

You read that and then aren't sure what the problem is? It can't find that file. Where is it on your computer? There are only a couple of places the IDE is going to look. The file needs to be in the libraries folder inside your sketch folder.

well thats the wavehc.h file and waveutil.h file are both in my libraries folder that is in my arduino file. So they are where they are supposed to be but the sketch/ide program doesn't say they are in there. That is why i am confused

Delta_G:
What's the path to the library file? It has to be in a folder with the same name as the .h file.

tytytytyty that worked. All i had to do was to make sure like you said that the files that i talked about were in a folder that had the same name. It works now. Thank you so much

Double posting on the forum is not cool!

Technically, they just have to be in a folder, it doesn't have to be named the same as the header file.

I've put a lot of the small, general classes I've been making (like wrapping_integer.h, debounce_filter.h, digital_filter.h, eeprom_ring.h, etc) into a single utilslib folder, and I've had no problem using any of them in my sketches.
