Gregory's ServerThere has been a game jam this week, so it's distracted me from some of this vocal synth work.
Velum support comes next, which is what is needed to get nasal sounds.

 Porting the nasal sounds has been a bit of a bumpy ride. I have introduced a NaN somewhere. This kills the DSP. Now I need to track down where it has been introduced. My approach has been to use panic and counters to iteratively bisect and find the earliest instance of a NaN. It's slow and tedious work. The NaNhunt will resume tomorrow. @patchlore  I made an oopsie and now the particular shapes I sculpted for this demo don't work anymore. Had to sculpt some new ones. They are okay enough though not as loud and pronounced as this one. Anyways, nasal/velum control seems to work I think. It's now a slider on the demo page. I've also turned on 2x oversampling, which will hopefully smooth things out a bit:  @patchlore this project is super cool! My only experience with DSP/synths is in C++/JUCE, but I've been wanting to learn how to do it in Rust. I'll have to give this project a look @reillypascal still learning things. the actual DSP programming feels pretty similar to how I do it in C, at least with my current coding style. I'm sure I'll get rustier as I go. Rust is more strict about number types (float vs int), and has some funny notation for math functions (x.sin() instead of sin(x)). There is a huge performance difference between debug and release builds. |
@patchlore it is absolutely fascinating seeing you implement this.
Do you have any pointers for someone who would like to learn more about the theory? (I reckon it's your domain of specialty, right?)
