Question: How are waveforms displayed within a DAW? In general: how does a DAW converts a wayform into an image?

It depends a lot on zoom level and view options. If zoomed in where each pixel is less than or close to a sample's worth of audio, then you'd draw the sample as one or more pixels, either as rectangular sample if you want to show the encoded sample, or using sinc interpolation if you want to show the analog representation of that signal. If zoomed out so that each pixel represents multiple samples, then you'd likely want to look at all samples in that represented interval and find the minimum/maximum, then draw that as a range (unless you had a rectified view enabled, etc). For efficiency you likely will want to cache lower resolution views of the underlying audio, too (e.g. .reapeaks) so that you don't have to look at millions of samples to draw the view. And you might also want to do some spectral analysis for things like spectral peaks.... 1 Comment...

Question: hey jf- is the ufo / uap topic on your radar? why are people NOT talking about this!?! is it not THE most profound,game changing or important conversation we as a species could have right now??

tbh I'm not sure there's a there there. So the story goes, back when they first started testing jet aircraft they'd have the pilots wear gorilla suits so that if prop-powered aircraft pilots saw the jets, the pilots would sound insane ("there was a gorilla flying a plane with no propeller!). With so many secret aircraft developments/testing, it's really not unreasonable to think that these are entirely various programs. The government stringing people along about it is really their goal, keeps people from looking too hard at their secret programs. While it is fun to imagine these scenarios, if there were another intelligent species involved, I think it would be incredibly unlikely that it would be able to be kept so secret. 3 Comments...

Question: Since mentioning your X60, what do you think about the old full height keyboard keys it has vs. the modern chiclet keys? I have a T420 which also has the full height keys and much prefer them to modern laptop keyboards.

Question: My kid is 8 and is way more intelligent than me which makes guiding him very difficult. He knows html/css/js/python already, he can build websites and simple games. Where should he go from here? Just keep learning languages and fiddling with them? Is there a specific path you would suggest or should I just get out of his way and let him find what he likes?

I really like my Thinkpad X60, which is something like 15 years old, but if you want something for 2050 you'll need something newer. Maybe get one of the

upgraded Thinkpads with Libreboot etc

Question: I feel that this question has been asked thousands of times. But what is your opinion on AI generated art? In general: AI generated content, code, text, etc.

Reply on September 28 2023, 11:45am:

It's interesting and cool (amazing what can be done), but also not that interesting nor cool (e.g. it's hard to feel moved emotionally by it). Definite utility value though. Which makes it less like art. I don't think that machine-generated content should be copyrightable, at any rate! Not without substantial human involvement. Comment...

Some value there, but in general my feeling is that there are significant enough differences between DAWs that any export/import you'd do would be sufficiently lossy that it doesn't get to be of terribly high value. But we'll see... Comment...

The audio processing threads are mostly all realtime anyway, shouldn't help much for that. Maybe for background tasks like building peaks, but those aren't really time critical anyway. 1 Comment...

Question: Any change to have a closer look at __LICE_SC_INTERNAL? It looks like that __LICE_SC does not like passing a LONG argument as used in LICE internally for RECT points, int argument works as expected (also previous implementation). LICE compilation fails with an error C2665. :(
