How can we play white noise/static at the same time as the dits and dahs?

Question

We are playing both the static and the dits/dahs as AudioFormat files using SourceDataLines, but as far as I can tell, you can only have one line open on Java at once. I am unsure about trying to combine our sounds into one line because then I don't think we would be able to adjust the volume of the static and the dit/dahs separately.

Answer 1

I believe all you have to do is just put them in different threads and it'll work. With our project, whenever we want to play a sound, we call a method that creates a new thread, and inside that thread we have all of the stuff needed to create the sound that we want, including calling the SourceDataLine object to play the sound, which is .write(byte[], int, int).

We start a new thread by doing:

new Thread(() -> {

 //Actual Code goes here

}).start();

I hope this helps!

Answer 2

Hmmm... my hunch is that it might be better to just use one SourceDataLine, and create the white noise by manipulating the code that generates the audio that you want to play. Try adding small random numbers to the waveform being generated?
