The screenshots posted by Rollin appear to be resampled, reducing the visibility of the effect, and adding new blended borders. But it is still there. The minor graphical flaw resulting from this flatness is that the bars are poorly defined where the gradient happens to randomly match the color/brightness of the window chrome - the first 25 percent of the level meter. A border is additional protection against this, why the transport icons look as they do, being white on white.

Scientific Discussion / Re: Help me understand why sound is one dimensional
Last post by Phanton_13 -
All this problem lies in the definition of dimension, as it varies with the context from the classical 3 spatial dimensions + time up to the multiple dimension in quantum physics. Sometimes you can argue the existence of hidden or omitted dimensions.

In the case you can argue that audio is 2 dimensional because it needs 2 elements to exist, magnitude (pressure) and time, after all audio is the information conveyed by the difference in pressure over time, even if its commonly represented as 1d vector because of its simplicity in this representation it exist a hidden dimension that is time because each position in the vector represents concrete time. It's possible to represent each point of audio as list of [pressure, time], this representation can led to variable sample rate audio, something exotic but plausible.

Also I can tell that normally a 1D vector is actually a 2D object because we normally omit the magnitude (weight, dimension) of the element in the vector to define its dimension. Basically we have a 1D vector of 1D element making it a 2D object. Or we can represent a vector by a list of [magnitude, position] demonstrating that a vector is a 1D representation of a list of 2D objects.

The devil of this discussion is hidden in the language and concepts.

I try to give you a logical explanation...
Thank you for your really interesting and valuable explanation. It seems to be right story. Unfortunately, 1. not fully right; 2. it only affects the surface, not the deep waves. As a result, what appears to be true, in the end became false. Half-truths are dangerous things, they deceive people.

Explanation little later, I am busy now.

Interesting thread! I'm not a mathematician, just an IT guy with barely enough math knowledge to be dangerous, but hear me out.

It always seemed to me that a waveform is something that can only be approximated. Unless it's generated by a function, that is (like a sine wave.) In music, the waveforms can only be approximated since the underlying sounds are very complex and chaotic.
Have you considered how waveforms not generated by a function are created?  It isn't like they are created by some algorithm used to approximate sound.

The actual complexity of a waveform makes it a very fractal-like structure. As such, it might make more sense to assign a fractal dimensionality to waveforms, which probably lies somewhere between 1 and 2?
Fractal-like?  That's quite a leap.

Captured this live from the BBC World Service. It's a good test sample with background human noise.

I think --bitrate 12 --set-ctl-int 4008=1104 sounds slightly better than --bitrate 12.1. But the differences are subtle.
