When i mentioned 'digital' i was referring to CD/Redbook 16/44k1. My mistake, as it could be due to 16 bit dynamic range.

I think people hate digital because it sounded like nails on a chalkboard for a long time.....now that it’s been around awhile it’s a whole lot better.

I think if it hasn’t already it will soon alleviate the term ‘vinyl sounds better’

I stream some 16/44.1 stuff that sounds undeniably better than most 24/48 and even 24/96
 
Editing digital data will be more accurate with more samples.

johnego,

Thank you for that. In my visual work I mash in 16bit and resample down to 8bit prior to print. Like with audio, it is a lot easier to make a good 16bit digital light capture than an analog output to 8bit CMYK ....... somewhat analogous to audio recording and playback through speakers.

Forgive my tendency towards the obvious, but I am learning a lot by listening here. ToS

BTW, I think digital audio is amazing. I have an extensive collection of vinyl, but no turntable. When I finally get one, I shall rip everything straight to FLAC.

Have you any idea what you are wanting. I have an erm excess of tables from projects I shouldn't have considered 🙂

billshurv,

Oh YES!!! I have been following the BD v DD thread, and been thinking that maybe something like a refurbished 20th century DD would suit me just fine. Although, I have no objection to a BD. Either way, you sure do know what you’re talking about, so I guess all your kit is set up like as new. Have you something you would like to part with? :wave:

I hate digital, because it usually sounds inferior to analog.

Q.E.D.

Don't know, I can't tell blind a damn thing between a SOTA FLAC digital recording and it's 192k MP3 lossy conversion. Call me deaf, I don't mind.
 
I have always thought that recordings made with high sampling rates actually sound better after being mashed in the editing process and then reduced to CD 16bit playback. More nuanced information makes for a smoother better sound. Am I right? 😕

Historically that has been the case, subjectively speaking. Of course, the basic math of sampling does not fully model the complete behavior of real world acquisition and or possible subsequent numerical processing errors, either errors in time and or amplitude as audio is captured by an ADC, or as those errors propagate through DAW numerical calculations.

Similarly, DSD often is found to subjectively sound better when played back through today's physically realizable sigma delta dacs, although some dacs highly optimized for PCM can sound almost as good.

IMHO, of course.

Anyone can try

http://pmacura.cz/13+14k.zip
(13kHz L, 14kHz R)

http://pmacura.cz/20+22k.zip
(20kHz L, 22kHz R)

Beware of level!!
Left channel is one frequency, right channel second.

I can hear 13/14kHz test, but no intermodulation. I hear nothing from 20/22kHz.

Again, take care about volume - your tweeters are in danger.

I understood that the mechanism was IM within the outer ear, so we
expect to hear it when the ear is exposed to both tones.
 
Fact is many people hate digital. I guess it is due to 'poor' technology adopted by the industry leaders, i.e. delta sigma with its 'risky' filters.

Very preliminary trials with AK4499 suggest that a clear step improvement in sound quality is close to hitting the streets. Even running in the less-than-best performing DSD64 mode, it pretty much leaves DAC-3 in the history bin. All in IMHO, of course.

Yes, I understand what you are saying - thank you.

There are very similar problems with digital light capture and subsequent processing. A common complaint amongst artists is that ‘digital looks dead’ - as in everything looks the same, and has a corpse-like quality. I have gone to great lengths with my own digital work to overcome this, and I think I may have succeeded - although I will have to wait until my one man show goes up next year. Then I will be able to gauge the visceral reaction to my pictures. I love analog film, I miss working with it, but I do now believe my recent digital work makes up for it.

So, within the context of this discussion, I can fully understand and respect why John Curl says he prefers analog and does not like digital.

Have you ever truly tried it blind? I don't know about 192 kbps and MP3 (borderline bitrate, old codec), but I would be shocked if anyone could pick 256 or 320 kbps MP4/AAC from FLAC in normal music, not specially chosen test signals. Maybe with training and practice.

Never done it blind abx..... but have tried flac vs mp3 and mp4

Your right at lower levels one would be hard pressed to tell a difference (especially mp4)but at volume it’s pretty dang obvious.....at least on my system with familiar music.

Yes the things you can do with digital is slightly mind boggling.....just a matter of re learning.
