To activate the looped swing mode, just add "swingl.wav" and "swingh.wav" to any existing font.
What directroy do the "swingl.wav" and "swingh.wav" go in? /hum or /swng or doesn't matter?


If you're using subdirectories for effects, each effect should have it's own directory, so it would be:

   swingl/swingl.wav

and

   swingh/swingh.wav


Really no need for subdirectories for effects that only have one file though, so just swingl.wav and swingh.wav is fine.

I tried this some months ago, haven't worked on it in a while.  No sound fonts/wav's for buzz sound. Yours sounds pretty good!

Got this implemented in TeensySaber now, but testing/tuning will have to wait until tomorrow.
Hopefully I can find some good looped sounds...


Sorry if this has been answered somewhere else, i haven't seen it yet in my reading here but, Do i need to make or modify sound fonts for this to work? or is it just taking a soundfont and renaming the file?

The sound font has to be modified, at least a little bit.
Basically you have to create two more hum sounds, one with a slightly higher pitch and one with a slightly lower pitch.
One reasonable simple way to do so is to use a command called "sox"

Code: [Select]
sox hum.wav swingh.wav speed -180c rate -v
sox hum.wav swingl.wav speed 150c rate -v

This works, but the result isn't quiete as awesome as what Thexter was able to do.
More interesting results can be obtained by taking the hum from a *different* font to create the swingl/swingh sounds.

cool! so if i wanted to duplicate thexters results as close as i can id need to get into manipulating my own fonts? Or i think you mentioned in a message that hes using slightly different hardware? Im really interested in diving into the sound configuration. Im just waiting on a breadboard to come in so i can start learning it

He uses different, but very similar hardware.
The bigger problem is that he uses different software. The looped swing implementation in teensysaber is based a description of what his V1 code does, but it's not identical. I think it works pretty well, but I haven't been able to make it sound as good as Thexter's demos. Not sure if that's because his code works better/differently, or if he just has better sound fonts than I do.  According to Thexter, Smoothswing V2 blends many more sounds than Smoothswing V1, but that's about all I know about it.

Fascinating. Im very interested in this aspect of saber building! My favorite thing to do when dealing with plecter boards was the tuning aspect of it... Making the sounds feel as responsive as possible.  Ive been considering making my own sound fonts lately and the smoothswing tech im seeing is really igniting that interest again. I work in film and im going to start asking some of my buddies in sound about making sound fonts. I might shoot you a pm her soon for some advice/ things i should research. Thanks you guys for all you do!

If you haven't read it already, I suggest starting with this excellent article: Lightsaber Sound Cookbook
