i know how to end aliasing

[Architeuthis]

i know how to end aliasing for everyone and forever: sva

'standard vector audio'

the concept is this. a text file (compressible and efficient for changes) becomes instructions to generate audio. it is alias free because i personally hand craft the entire engine to be fractal in nature, infinite detail, yet it creates any electronic or physically modeled sound you want using beautiful and simple math equations, it runs in your browser and so it will run anywhere.

soundemote.io

a sawtooth is just a fedback speed-limited sinusoid
an envelope is just a pinged oscillator and we measure the peaks and troughs to find the envelope
a filter can be a simple delay equation or an oscillation network
etc.

the main difference between my engine and every other engine: my engine requires calculating sin over time rather than with sin() or even a cheap sin, which completely changes how everything works. it is 100% alias free at every samplerate. it means sin becomes the foundation of everything so you get gaussian math for cheap. and sin is cheap in general, just a memory access.

the end to aliasing is the last technological problem humans need to solve. this is the last human problem. ai will solve everything else after this.

this is also perhaps how black holes work. i am essentially creating a black hole for aliasing in timespace. you could think of it like that. or you could think of it as: i am putting a speed limit in our audio simulation universe that is half the samplerate.

sva would allow online multiplayer audio synthesis and math collaboration for scientific and musical experiments.

good for you, if this works for you, but such overhyped bs posts with 0 evidence or content are a waste of time for everyone.

There is no known solution to human arrogance that I am aware of.

#1. im not selling anything
#2. i explained proof in my first post
#3. im just trying to help
#4. my entire website is proof of this concept
#5. i can prove it with 100% clarity given time or money. I have 0 money right now, im out of money and time. i need support, not criticism. actually, ive already proven it pretty much, i just need to see if it works in practice.

sawtooth is not a feedback "speed-limited" sinusoid. i might be wrong, but what you try to describe feels the same as PM (or FM) self-feedback, which really turns a sine wave into a sawtooth-ish waveform, but this is not anti-aliased by definition. you can limit the PM feedback gain so, that your waveform won't create (many, or audible) harmonics above nyquist, but this is not solving aliasing at all.

it's tiring to read AI slop posts all the time in this forum. i know it's exciting to be able to do stuff you've always dreamed of, but never had the time or money or knowledge to really dive into it... but stating that "you solved aliasing" based on LLM feedback to your prompt is disrespectful to all the people who wrote all the technical / scientific papers in the past decades that your LLM hallucinates about.

and i also want to be clear: i'm not anti-AI, i'm using it a lot daily, and it helps me a lot in saving time. but DSP and sound synthesis is not something any LLM is really good at ATM.

these claims do not line up:

i explained proof in my first post

and

i can prove it with 100% clarity given time or money.

if the proof was already provided, you should be able to point to a paper or some documentation that describes your idea clearly and precisely. terminology such as “speed-limit” was never defined by you, so no one can know what you actually mean. that makes your posts a complete waste of everyone’s time. there is nothing else to discuss here, only your posting style and behaviour, while you are just hyping your own site and try to raise traffic with such posts.

some hints: don't publish stuff if you can't handle criticism. and... posting the same answer 3x to different users, in which you claim things that no one even brought up: makes you look exactly like a bot.

https://soundemote.io/#/last-clock <- the start of proof. i will need concrete evidence but i don't have time to keep coding right now, out of time and money. the equation in the article is just one example. i already have a more robust sin generator (it needs mathematical reduction still):
the definition of a sawtooth in my universe simulation is described as a sharp impulse followed by a gradual decay. you are over-simplifying my suggestions by saying it's simply a fedback sine to create a sawtooth. but it is what i said, however, that's not the end of the story, that's the tip of the iceberg, and/or just one of many ideas of how to get a sawtooth out of a sinusoid resonator. zero-aliasing is the goal. perfect waveshape is not the goal.

1. speed limited waveforms creates organic squeaks, hums, growls, screams, gurgles.
2. perfect waveshapes create perfectly horrible aliasing.
3. calculating sin() causes aliasing because of the very nature of perfect instant-time calculations, instantaneous time breaks the laws of physics therefore breaks the universe speed limit and therefore causes aliasing.

thanks for the reply. you’ve just confirmed everything i said.

i hope you're aware that you can already generate perfectly bandlimited and alias-free saw, square and triangle waves since a few decades using BLIT oscillators. the basic idea is actually related to what you describe, but instead (and opposed to your definition of a saw) of exciting a decay with a sharp, broadband impulse, BLIT uses a bandlimited impulse derived from the sinc function, which is the time-domain representation of an ideally rectangular, bandlimited spectrum. integrating the resulting bandlimited impulse train produces a sawtooth waveform.

related techniques such as BLEP and minBLEP address the same class of discontinuity-related problems, while polyBLEP (and polyBLAMP) is an efficient polynomial approximation of the BLEP (and BLAMP) correction. lately, Signalsmith came up with the idea of elliptic BLEPs (for which he did a really nice presentation).

you can also generate perfectly alias-free periodic and non-periodic waveforms using additive synthesis, although it may not be particularly CPU-efficient. you can also generate perfectly alias-free waveforms using wavetable synthesis.

so, in terms of oscillator waveform generation, humanity solved the problem you are trying to solve a long time ago, while you are approaching it now through completely debatable assumptions.

and i believe humanity has many more, and far more fundamental, problems to solve than aliasing.

• DSFOscillator.hpp:
  • perfect(?) bandlimiting using Discrete Summation Formula
• DistortionOscillator.hpp:
  • near perfect soft-clipped style bandlimiting
• Ellipsoid.hpp:
  • near perfect bandlimiting if you dont go over sharpness thresholds
• Supersaw/Hypersaw.hpp:
  • uses polyBLEP
• JerobeamSpiral.h:
  • naturally bandlimited to some degree
• PolyBLEP.hpp:
  • near perfect bandlimiting

missing from the list: zero aliasing because i havent had time to experiment. bandlimiting is impossible to calculate [perfectly] because it requires a chaotic equation that you can't know the answer to until it occurs. so i skip the middleman and make everything a speed-limited chaotic equation from the start.

silly ai generated words explaining the math: https://github.com/elanhickler/soemdsp- ... /README.md
