G.722 is just as good as 711 but I think there are some licensing entanglements that prevent most folks from using it.

Some of the HD offerings are better mastered than the original (more dynamic range for example), but when those HD tracks are (properly) converted down to 16-bit 44.1 khz, double blind tests have shown they sound just as good. Here is a good article on the subject. https://people.xiph.org/~xiphmont/demo/neil-young.html On Fri, Oct 5, 2018 at 12:02 PM Ken Hohhof <af...@kwisp.com> wrote: Interesting, I’m 68 (and people my age are reputed to have ruined our ears at concerts) so my hearing should be shot. But I can definitely hear the difference between Red Book CD and HD FLAC. It all depends on the source material though. The best CDs sound better than the worst or even the average HD audio. I think where HD audio shines is live recordings, you can close your eyes and feel that you’re right there. The alternative I guess is if you have a really good home theater setup, then you get high end video and audio together. Strangely, I see lots of customers with big screen TVs but rarely a good surround sound system to go with it, maybe just a soundbar.

Even the silence has that tiny bit of hum and reverb in it. I like how tubes color the music. It seems more “live” for some reason. From: castarritt Sent: Friday, October 5, 2018 9:13 AM To: af@af.afmug.com Subject: Re: [AFMUG] OT - autotune To be fair, I can see the difference between 1080p/4k/8k with a big enough screen viewed from a close enough difference. I can't hear any difference between 16bit PCM and "high res" audio. Hell, I can't even claim that I'm able to perceive a difference between 16bit lossless and a well-encoded MP3. The only reason I keep my collection in lossless formats is that simply knowing the encoding is lossy somehow takes away from my enjoyment.

Not just to polish up a few off-key notes, but the whole song is heavily autotuned. For anyone on the list who lives or travels outside the US, is this just a US phenomenon? Or is it everywhere, including Europe and South America? I heard the studio version of this song on the car radio last night and had to Google the lyrics to find the singer, who turned out to be from Germany. Obviously capable of singing without autotune, or at least performing live without lip syncing: https://www.youtube.com/watch?v=38FORtUWDKA I don’t know where the recorded music industry is headed. I try to find high res FLAC downloads and most of what’s available is remastered stuff from 30+ years ago. The few “audiophiles” today seems to be listening to vinyl on their tube amps. Yet I saw an ad for a $15,000 85 inch 8K resolution Samsung TV, shipping later this month. Video and audio seem to have gone opposite directions. (I estimate that 8K streaming video will require up to 100 Mbps Internet speed.) -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com ---------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
