Care to elaborate, or be a bit more specific with regards to which parts you are commenting? I wasn't aware the post had much logic to speak of, it's more like a list of facts.
To my knowledge there are no lossless compression that can achieve below 900kbps for a typical musical passage.
With today's available lossless compression: It depends on the passage and how dense the information is, if the passage has low information density, it can be 500kbps. And in some extreme cases with very very sparse information density, it can be 300-400kbps or even 100-200kbps. But for a typical musical passage, it's anywhere from 500kbps to 1000kbps.
But the point is, for most music, anything below 500kbps cannot be achieved without being lossy. (EDIT: This assumes typical music tracks recorded on 16bit 44.1kHz)
It sounds a bit like your perceived definition of lossy is "sounds worse than the original",
As I have stated multiple times, it is audible. You can argue how important that is, if it makes a difference in listening sessions, etc., like many other here have. That is not the scientific point that I am making, I am simply making a scientific point that it is audible, whether you like it or not. Plain and simple.
Just like if I were to say that gravity on Earth changes slightly depending on the altitude, you can argue the importance of it in practical terms, but again, whether you like this scientific fact or not, doesn't change the scientific fact that gravity indeed changes slightly depending on altitude.
while what it actually means is that data has been permanently removed from the uncompressed source. It's a binary definition of the type of compression being used. Is data lost (lossy) or not (lossless) when reconstructed. It is not connected to bitrate. Either it's lossless or it isn't, irrespective of the bitrate.
You misunderstood. Name me one lossless compression that can achieve below 500kbps for typical musical passage. As explained above, it doesn't exist. Hence, if there is anything below this, it's lossy.
So to talk about high or low bitrate for a lossy format, does not related to the bitrate of a lossless format. It's comparing apples to pears.
It does, as explained above. Name me one lossless compression that can achieve below 500kbps for typical musical passage.
A lossy format can have a low bitrate (meaningful amount of data is lost in such a way that it is audible or high bitrate (we can't discern it from the lossless source).
A lossless format can either be uncompressed, then the bitrate is what it is. Or it can be compressed, then we get 20-50% compression depending on the music, and bitrate varies throughout the track.
As explained above.
