I only see opinions and preferences in that thread.

Any hard statisitcal facts on which has better sound quality?

The thing about it is that hes trying 2 bring a new style tho just like he did with Just be and it worked. they songs areunt TOO HIGHT up. but the vocals acaully are the best thing in 2007. The Track Carpe Noctum is like traffic but it hink he could of prefected the shit ouf it. but generalllyy its an amazing album...oh and Ten Seconds Before Sunrise is like Forever today TIMES 12

Sound quality can be very much down to preference itself... A lot of people prefer the clean sound of a CD to the warm, slightly distorted sound of vinyl and vice versa.

how do you measure sound quality?

honest question.

Analogue signals don't have a bitrate, so that can't be used to compare.



*A bit more depth into your original question...*

Technically, analogue sources can be "perfect" quality, if no noise is present. However, there's always noise and recording defects (scratches, crackles and dust etc on a vinyl pressing for example).

Digital recordings quantise the sound ("round" the signal to fixed values in both time and amplitude), so in this sense lose quality, but are much less susceptible to the effects of noise and smoothing can be used to get the signal nearer to the original analogue signal.

So basically it's just not as simple as one being better quality than the other, it depends on the sample rate and sample depth of the digital recording (how accurate the quantisation is) and how much noise and distortion is present in the analogue signal.

I suppose the intuitive answer to that would be to measure the likeness of a transmitted signal (i.e. the signal after it's been transmitted through a medium in either analogue or digital format) to the original signal

Those who know about signal processing will know that using a cross-correlation function is one way to do this.

This is what I'm looking for, thank you!

I'd like to see readings that explain this and go more depth into it.

Really new to this stuff, I want to learn...

It also depends on a person's hearing, and how well they can determine distortion from what's not distortion. At what degree have they ever heard quality recordings, and what was the program in question when they drew to this conclusion.

Sound is too subjective why there is no golden rule of thumb on what's best.

Bottomline. Your ears are the deciding factor, and more people will trust their ears over any research if their ears don't agree with the end result.

Beautiful Stu, Eric would be proud.
