Question: I want to mix two audio samples. Adding them together and dividing by 2 reduces audio gain. What should I do? (using realtime)

Question: I tried to create a JS Notepad, and the only way I know to make a js plugin accept input text box is via the small boxes beside sliders. Is there any way to create big a text box and make a notepad out of it.

    Not easily, no. better to use VST or CLAP and native window controls for that.

Reply on March 26 2025, 8:02pm:
    not directly but if the underlying video encoder/decoder does, or if you have VSTs that do, then yeah.

Question: why so many ides' ? why so many frameworks? Why so many libraries? Why so many apis' ? I don't understand this whole programming thing. Is there a lot of dependencies in Reaper as well or you're type of guy to write things from scratch on your own?
Asked by Rano (45.250.49.x) on March 21 2025, 9:20pm
Reply on March 21 2025, 9:40pm:
    definitely prefer to keep dependencies to a minimum! I ran a mastodon server for a little while but the dependencies were so numerous it was disorienting, hard to trust that many supply chains!

Question: Upon init of a csurf plugin, Reaper calls it with a parameter called "errStats". It does contain the error state of csurf plugins initialised before. Should a csurf plugin just init this to zero before using it?

    Do not clear it -- set bits if errors occur: 1 if you couldn't open the MIDI device, 2 if couldn't open MIDI output, 4 if couldn't open some sort of network port

Question: What is your workflow for creating Reaper's changelogs?

Reply on March 21 2025, 5:44pm:
    We have git commit lines like "- some change" or "+ some change", then a script that auto-generates the changelog for the builds based on those. when doing releases, we then manually edit/fix typos/reword/etc in the whatsnew.txt file that is in git.

Question: What do you think is the best CPU these days (also with music production in mind)? Intel Ultra, AMD Ryzen, or Apple Silicon? If you were to buy (a) a laptop and (b) a desktop right now, what would you get?

Reply on March 16 2025, 8:33pm:
    My 5 year old M1 MBA is still amazing to me, don't think I would change much about it. For a desktop though I'd probably go with a Ryzen, for variety.

Question: I tried using the Lagrange interpolation and the true peak specifications to create a true peak limiter as JSFX, but the hardest part is getting it to truly catch the true peaks so the ceiling doesn't overshoot. It seems no one has been able to do it afaik. All the jsfx limiters available are all peak limiters. And in fact, Reaper's True peak limiter is not in jsfx, it's a VST. So are we ignorant on how to implement it in jsfx or it's just a limitation of the jsfx capabilities?
Asked by Wing (102.176.65.x) on March 15 2025, 9:00am
Reply on March 15 2025, 3:20pm:
    You could do it, the loudness meter JSFX has true peak metering, so you could apply that to a limiter. The EEL2 language is turing complete, so really anything you want you could implement (unless you need too much RAM...).

Question: How far out would you guess some legit claim to AGI is? Sure, we'll bicker for years afterwards about whether it qualifies and how to measure that, but someone will be first to a legitimate claim to being first.
