AI Thread Summary
The discussion centers on the mathematical principles underlying MP3 compression. One participant expresses a desire for a deeper understanding of the algorithms involved in MP3 encoding beyond basic knowledge. Another contributor suggests that while the MP3 codec can be represented mathematically, it may not enhance comprehension of its functionality. A link to a resource is provided for those seeking more detailed information about MP3 compression. Overall, the conversation highlights the complexity of the mathematics behind audio compression formats like MP3.

I have heard how math is related to MP3 compression format, anyone know more and would like to share his/her canny wit?

Mathematics news on Phys.org
While that may have satisfied my General knowledge of MP3, I needed a more in-depth view of the mathematics and algorithm of MP3 compression.

I think the MP3 codec is just a computer algorithm. Sure, you could rewrite it in the form of a bunch of equations, but that does not give you more insight into what's going on. I have never seen the equations, but based on the above link you can probably make some educated guesses...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'Imaginary Pythagoras'

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
