Off-Topic / Re: Just doing my part: Trump is an idiot
Last post by fuflo -
I don't follow politics very much, but during these moments i take it as an exercise for my own mind.

Remember when everyone was hating bush, and he was reelected for second term? yep.

I guess the majority or people voted for him. This just strengthens my point that the majority of people are idiots. Not just the US, but globally.

When you look at other countries/regions, the people put in charge, sometimes it boggles the mind same as with US.

But then there's the other side. What if, just what if trump is testing the system for what he can get away with? Sure, you can call him an idiot, but he's a successful business man, so he did something right, at least in the past. 'Right' being debatable and another topic in and of itself, the shady business practices, capitalism and all. Still. He is considered successful in the current state of our world.

So he must not be a complete idiot. Maybe for him it's just a game. He achieved the highest possible position in the country, possibly the world, with the US military power.

Or maybe it's just me overthinking it.

I don't know what that is, but it's "artificial music" (digital/electronic/synthesizer) right?

That would seem to be the case for most of the album, yes. There's some songs here and there where a real electric guitar is seemingly used, but not this track; most of the album seems to use synths/VSTs. I would upload a 30-second sample but the wording of TOS9 makes me wonder if I'm only allowed to do so for the purpose of codec testing, and not for the purposes of this specific thread (which isn't codec testing, but so that you can see if it's "artificial music" or not).

Does it sound OK?

It's not continuous so it's probably not noise or interference.     I'd guess it's a (artificial) high-hat or some other intentional percussive sound on the beat. 

It does indeed sound OK, like, there's doesn't seem to be anything unnatural or distorted; it all sounds musical. And you're right about it not being continuous, most notably at the end when the track ends and the synths begin to fade out. This is coincidentally also when the percussion stops playing, so it being a hi-hat makes sense — but what hi-hat is concentrated close to 18kHz, even if artificial? I mean, most people over the age of 30 can't even hear that.

I guess if I can upload 30-second sample, it may help diagnose what exactly this thing is. If I can, let me know which segment of the track would prove most useful: the ending 30 seconds, or the first 30 seconds.

Scientific Discussion / Re: Help me understand why sound is one dimensional
Last post by jsdyson -
IMHO the 1D point of view don't conceptualize the reality because all audio measurements are performed by people who have the sound field in mind.


If a person has a picture of what they expect the sound field to be -- and then uses a singular real data point, aren't they really sustituting 'fake' (not necessarily invalid) effective data points for real ones?  No matter what you are imagining, there has to be some kind of framework -- and in space, there are normally 3 dimensions.  One can abstractly create more dimensions for some kind of analysis purpose, but in reality there are three dimensions in space.   Adding more dimensions isn't just describing space, but rather some kind of hyperspace (no scifi here.)

environment given multiple scalar sound measurements vs. time.
John

I don't understand "scalar" part of the sentence, you mean that we can vectorize the sound propagation with a microphone array... how ?
It can only be performed in the far field IMO (if it is possible)





I am not saying how (by what method), except that information about the environment can be inferred by using multiple sensors.  A single sensor with no other information would only provide 1 dimension of data.  Perhaps the distance between two impulses can be measured -- but what is the reference point of the two?  SO, one sensor basically gives you the ability to detect sound at that point only (no directional information.)  With multiiple sensors, things like reflections and signal intensity can start to be used to guess better at directions.  I am not claiming exactly what kind of data about the environment that can be figured out.  For example, a lot of information can be figured out about earthquakes by simply listening -- not even pinging of any kind.  By using more sensors -- more kinds of information (dimensions) can possibly be derived.  By explicitly adding a controlled source of some kind, even more information might be able to be obtained. (or, maybe with a controlled source of some kind, the precision might be greater.)

Being able to type in the numbers looks great.  I think the splitting of the UI elements is on the right track as well; I'm specifically interested in the playback rate section (I don't see it in the image), and assuming that I can display the playback rate section by itself, then I think what you have looks good!
