Process on soundfont creation

Sound Fonts
21

In the polyphonic case, most effects are never interrupted, we just play them out.
However, we can always start another clash/blast even though the first one isn’t finished yet, assuming there are still wav players available.

In the monophonic case, each effect becomes the new hum as soon as it’s started, so it can always be interrupted by another effect. In some cases we limit the number of interruptions per second though, since playing a new clash 20 times per second just becomes noise.

Is this the case yet, or do we still need to run the high pass filter?

So, it’s certainly possible to do the filtering in ProffieOS, however, I don’t know if people actually do.

Cool. Is this how you do it, Brian? Or do you run the filter in Audacity?

26

If I’m making a font, I’ll just filter it from the get-go.
I find no detriment to having the filter active in all configs anyway, so I just leave it on.

I’m almost at the point of just doing both of these. It barely ties up 1% of total file size, even less if you’re on a V3 board.

FWIW this tool will now do many of the things listed above automagically :slight_smile:

Someday I’ll do part deux: advanced concepts. (mildly advanced)

So buy/get a poorly produced font, and this will clean it up and optimize it? Get out.

I use @NoSloppy ‘s font converter to ‘wash’ all of my fonts :slight_smile:

Proffie to Proffie ‘conversion’ is a lifesaver.

Hey everyone!

I recently downloaded Audacity to try and create my own soundfont based off the game Destiny 2. I’ve got a good set of samples set up, but I am having trouble making a Hum for the font. I’m wondering if it’s possible to cleanly loop the sound I have, or if it has too many unique elements.
Any tips would be appreciated.
Thanks!

11 seconds can be fairly limiting when trying to make a loop.
If you had 11 minutes, then then creating a loop would just be a matter of finding a spot where all the elements line up well.

33

For sure, I do have a longer sample of that sound, this is just the selection I got closest to lining up. What would you say is too long for a Hum? I think I saw somewhere it should be less than 15 seconds.

34

IMO it should be pretty long. 30 seconds at least so you don’t notice it constantly looping.

Sure can use that.

  1. Mix stereo down to mono.
  2. Take some of the end and copy.
  3. Paste to new track and make sure it starts at the beginning.
  4. Reverse the pasted ending part and fade it out.
  5. Fade in the first track beginning part, creating a cross fade between the 2 tracks.
  6. Check the loop sounds good.
  7. Select all and do menu Tracks>Mix and Render to New Track.
  8. delete 1st 2 old tracks.
  9. Select all and normalize to -5dB.
  10. Export as 44.1kHz (44100) 16bit WAV file.

Then you get something like this:

Here’s an old vid i did on this:

Awesome! Thanks for all the tips, I’ll definitely check out your channel and then mess around with my samples and see what comes out :smile:
