Digital audio and stress

I found the playing of vinyl fatiguing, I mean, jumping up and down every 20 minutes to flip and brush and then hoping the brushing did not produce too much static.
What man does not sit down to watch TV without the remote by his side?
I have been converting my CDs to mp3s and transferring them to a small bluetooth tablet. With a bt receiver connected to my amp, I can relax with tablet in hand and swipe through my albums and enjoy the music, just perfect.

...LP resolution is around 11 bits equivalent, give or take a bit or so, though confirmation would be nice

Not true. Digital has quantization noise, which limits sound quality hard (excluding noise shaping, which has its own problems). Dither can mask quantization noise, tho.

Analogue noise floor is soft, so one can usually hear at least one Bel into it. -70dB noise floor means a dynamic range of maybe 85 dB. Exact value depends on signal and noise spectra, that is why weighting functions such as dB(A) have been in wide use.

Digital systems have no dynamic range. Regarding amplitude, they have quantization noise floor. We, almost all of mankind is sitting in an ivory tower without windows. Our own digital creations have deafend us.

Whilst I don't wish to spoil the artistry at work here, this graph is a useful demonstration of the noise floor with a bit of dither applied. 16 and 24 bit shown. That noise floor may be 'hard' but its rather a long way down and a good 20dB below the noise floor of any normal listening room.

Fritz, I'm glad I'm not one of those tortured souls that listens to his equipment rather than enjoying recorded music.

There is absolutely not one correct statement in here. Congratulations.

High resolution digital TV must be particularly stressful for aging female TV presenters.

In the 1990s as the US inched towards HDTV, I thought "digital makeup" might be a good TV FX business, and/or a good specialty makeup line.

As for digital audio causing stress. It must, right?

I mean, people used to roll joints on LP covers, then they'd smoke the joint, and it would help them relax. So, with digital audio, there is the stress of finding a suitable joint-rolling surface, and if one can't be found, a lack of stress relief.

I was so over all that jumpng up and down and flipping discs, cleaning discs, worrying about discs. CDs were so much easier. Then I put all my CDs onto a hard drive, 1000s of tracks at the touch of a button. Hurray!

But I found that having easy random access to my entire collection made me less relaxed. I was always searching for something to cool to play, that song, that album, that something. ADD - arrggh! Going back to spinning vinyl made me relax and listen to an entire album. To enjoy the journey. If you have the discipline to not jump around from track to track on the music server, I say Bravo! :up: I can't do it.

For background music, I stream from the interwebs. No worries.

Hee! You can still keep a couple of your favorite old LPs around for auxilliary purposes, even if you're not actually listening to them. (I actually do this, although I won't explicitly state the purpose.)

Spooky, I was thinking of bringing this up and the fact that, for those of us old enough to remember the 'digital ready' stickers on everything. LP playback systems had less top end and the speakers were often tipped up to compensate. Also as Pano mentioned, the whole drive for flat in room response.

A tilt control would deal with this. Peter Walker was right.

Interesting as I have said that maybe its the extra detail that makes the difference, I know some early DVD players sounded horrendous and one of my favourite CD machines is an old Kenwood we have, will look up the model when I am back home... Also I tend to listen on my OB speakers these days that probably have reduced treble output, worth some investigation when I get chance.

So true - for that reason I don't relate to the people getting rid of all their CDs and vinyl. People come round and play music and they're always looking through your harddrive for the next tune - I didn't hire a DJ, I just wanted your company!

Facts or links to research and papers cos everything I have seen differs....

A CD case is large enough for a five skinner I am told..................
