Maybe in a new thread😬 128kbps .aac is crap which is why YouTube uses it. They want you to purchase the recordings based on watching the video, but not save the Videos instead of purchasing the songs. 576kbps .aac audio doesn't sound too bad though.

sandyk Posted July 9, 2019 Share Posted July 9, 2019 On the subject of low bit rate 128kbps .aac, does anybody have a preference with the audio of these 2 versions ? The .mp4 version is the original YouTube .mp4, and the other is a larger file size DVD format file with LPCM. The LPCM version was created by simply converting the ORIGINAL 127kbps .aac audio to .wav without any other processing. I will delete these videos in 24 hours. They can be played directly from DropBox. https://www.dropbox.com/s/c91wp17uq8ptvu3/Carly Simon - You're So Vain mp4.mp4?dl=0https://www.dropbox.com/s/1jvvd9lu7t4qlbi/Carly Simon - You're So Vain.mpg?dl=0 How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area.

MP4 is normal. Perhaps your phone doesn't like 1536kbps 48kHz LPCM? It sounds very good here directly from the Dropbox player. (I just tried it again after seeing your post.)

The .mp4 version is the same one without any conversion whatsoever, that I downloaded from Google and is an exact copy of it according to the Checksums, not that this proves anything.

Perhaps the reconstruction with more data points is part of the answer, but the resident know-it-alls dispute that original explanation from the designers of CD. Incidentally, I can also get a small improvement from low bit rate .aac by upsampling it to 576kbps which is the highest resolution available in .aac for my Video S/W.

No. I am simply making the point that differences in tonal quality between speaker drivers with identical frequency response can be due to cabinet resonances. You were reading far too much into my reply. Of course there may be minor differences in the Waterfall plot that most people are unlikely to be able to correctly interpret anyway.. P.S. We are now getting way off the original topic which is Speakers are Least Important which is completely wrong anyway. https://en.wikipedia.org/wiki/Waterfall_plot Ralf11 1 How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area.

That doesn't mean the speakers are least important though. With my original DCM QED 1A speakers I first saw a review of them in Australian Hi Fi where they also showed technical measurements including a Waterfall plot, which showed that they were quite a bit better than average for speakers back then. After that I then went to a local dealer along with another technical friend, where they were properly set up, and after hearing them bought them.
