As I said, I don't know the deep dark inner details of MP3 encoding, however, an average doesn't make logical sense to my simple understanding of using a single pass; it would need to see the "future". Further, I did find the following regarding VBR using a quick web search
So that reads to me that its not an "Average", and that the "Quality" is defined as a maximum bitrate I have a vague memory that when encoding MP3 there is a separate parameter for quality distinct from bitrate, which I would *guess* allows the encoder to control the encoding speed.
I NEVER said you were stupid (whatever that means). What you consistently did however was probably an oversight in typing, and your vague use/comparison of Khz with Kbs. One being a sample rate and the other being a data rate. You and I may know the difference but others reading this thread will only get confused by the typo. Sorry if that came across as confrontational or patronizing, it wasn't my intent.
And it is well known and generally accepted that encoding, decoding and re-encoding will lose more and more quality, especially between different formats or even with the same format using variable/questionable parameters. I didn't read the full page , however a simple web search will pull up pages like: http://scruss.com/blog/2012/02/21/ge...3-re-encoding/ In a perfect world with the correct parameters that MAY not be the absolute case, but we live faaaaar from a perfect world. The two images on the page tells most of the story, for those that just want a quick glance, without any reading.
A couple of corrections of what I previously said. oops
CBR is actually constant. I assumed and spoke of it as actually acting like VBR. I wrongly thought RLE encoding would of been a significant part of MP3
Mp3 encoding does use FFT as part of the encoding process, but only as part of the process / decision making.
Regarding the cups example, some water is lost because you pour the water too fast and some splashes out.
