AI Thread Summary
The discussion focuses on the Sinc function's role in digital audio processing, particularly in relation to filtering and upsampling. It emphasizes that for practical purposes, bit depth can be considered infinite, allowing for precise calculations. The process of two times upsampling is introduced, highlighting its significance in improving audio quality. The Sinc function is essential in this context, as it serves as a mathematical tool for creating filters that enhance the fidelity of digital audio signals. Overall, the content underscores the importance of understanding the Sinc function in achieving high-quality audio processing.

Introduction
This elaborates some of the claims in my insights article on digital audio.
The Sinc Function
The first link in my insights article has a section on filters, but I will detail the most critical case. The bit depth is assumed to be so large for all practical purposes that it is infinite, and all calculations are done at that resolution. To clarify the statement above, we will start with two times upsampling and how it is done. You put the...

Thread 'Is AI hype?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...

Thread 'ChatGPT Examples, Good and Bad'

I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
