in Core Library Questions • 2 years ago

try putting them in the same directory as the .PDE, not in the data directory.

I'm not familiar with minim's loadFile and where it defaults, but it might be best to give it the full path in this case to the data directory via Processing's dataPath() function.

minim.loadFile(dataPath("blackwedding2.wav"));

crapht, if you look at Minim examples, like loadFile, precisely, you will see the files are in the data dir.
katherine.beavers, if you are on Unix-like system, ensure:
- that Minim works for you on the provided samples;
- that you have the same case on the system and in your program.
Perhaps it has an issue with the format you use, try to use mp3 instead.
