Question: I made my own programming language in ChatGPT. Like, I have told it all syntax of it (like, for printing a statement, Data.Output(). And for if condition, i used "when". For 'else', I used "otherwise", and told it about integer variables. And made a factorial code in it. And wow, it actually understand everything and told me the correct output. And I also gave it some reasoning puzzles, which it actually solved. Woah!!! what kind of experiment you did with it?

Question: SWELL: At this point I am not sure if emulation was the right choice for long term sustainability/usability. Microsoft works with PALs which I cannot visualize conceptually but I guess is something close to the approach used in IdTech 4. Considering the parameters and the team size how feasible would have been for Cockos to pull something like this, if that makes sense at all for the time you made the cross-platform considerations?

Question: I don't understand how in Reaper 768pt sinc is considered very slow but R8Brain is fast. Isn't the expensive part of resampling the convolution with the filter kernel? What can R8Brain possibly be doing that differs so much from a simple windowed sinc? Is it just the method of convolution, direct vs FFT?
Asked by Erin (75.15.159.x) on January 21 2023, 5:09am
Reply on January 21 2023, 5:25am:

IIRC r8brain does big FFT AA filters plus a smaller size sinc interpolation, vs the 768pt sinc filter which is a combination of sinc interpolation and AA filtering, which is brute force. One advantage of 768pt sinc is lower latency if you're using it on FX. Comment...
