Thexter, would you share with us how you made your audio files? They sound so good.
I mostly use Sox (Sound eXchange)
SoX - Sound eXchange | HomePageThere's a thread
SmoothSwing V2 Font Creators' Discussion Thread | The Rebel Armory around font making, but since smoothswing is in its infancy, so is the art of making fonts for it.
One of the key takeaways is that a hum sound that makes a good main hum may not be a good candidate for a good swing hum.
Here's an example of the processing I do for one of my light-side fonts. inputhum.wav is the main hum, and lighthum.wav is a completely different hum that I feel has more "punch".
main hum:
sox.exe inputhum.wav hum01.wav lowpass 2025
8 pairs split into two parts, a and b:
sox.exe lighthum.wav pair01_a.wav pitch 120 overdrive 10
sox.exe lighthum.wav pair01_b.wav pitch 0 overdrive 10
sox.exe lighthum.wav pair02_a.wav pitch -60 overdrive 10
sox.exe lighthum.wav pair02_b.wav pitch 0 overdrive 10
sox.exe lighthum.wav pair03_a.wav pitch 200 overdrive 10
sox.exe lighthum.wav pair03_b.wav pitch 20 overdrive 10
sox.exe lighthum.wav pair04_a.wav pitch -100 overdrive 10
sox.exe lighthum.wav pair04_b.wav pitch -30 overdrive 10
sox.exe lighthum.wav pair05_a.wav pitch 180 overdrive 10
sox.exe lighthum.wav pair05_b.wav pitch 50 overdrive 10
sox.exe lighthum.wav pair06_a.wav pitch -50 overdrive 10
sox.exe lighthum.wav pair06_b.wav pitch 50 overdrive 10
sox.exe lighthum.wav pair07_a.wav pitch 140 overdrive 10
sox.exe lighthum.wav pair07_b.wav pitch 100 overdrive 10
sox.exe lighthum.wav pair08_a.wav pitch -70 overdrive 10
sox.exe lighthum.wav pair08_b.wav pitch -70 overdrive 10
