How To

Wave Generation

I'm working on an audio-based project and was curious how some of the data is interpreted to form the resulting audio wave.

I'm using a triangle wave and need to recreate the wave given the pitch, pulse width, and volume so that I can sample values from it.

Does anyone know how to create a mathematical expression to create the wave based on the pitch, volume, and pulse width of a triangle wave?

I think I know what this is for, Good luck!

Wait, pulse width only works with square waves?

I'm going to need to rethink this a bit. I really don't mess with audio on LowRes.

If you listen to this frequency sweep
Without touching the screen, you'll be able to hear some artifacts that may give some information about the bit depth of the audio.

@McPepic, I think this is what you are looking for:

Wait, you wanted a mathematical expression these waveforms in general (not the specific NX sounds), I can give you some:

For the other waves, here are a few approaches that could work:

Alright, thanks! I'll look into these for the project. God bless you!

God bless you too man!
