"> > SNR and resolution are two totally independent entities.
"They are two sides of the same coin, they are interchangeable terms."
So if you take a 4-bit 5 kHz-sampled digitized signal whose playback has virtually no measurable noise, the signal is of high resolution?
"> > The only thing noise does to an resolute signal is obscure the listener's ability to perceive the low-level information of the signal. And unlike a low-resolution signal, one can still hear the information well below the noise present in a high-resolution signal.
"You imply an infinitely resolvable signal, err no. Your are confusing a noisy signal with the effective noise floor."
Noise is noise...... Resolution is resolution...... Somewhere, in the early days of digital audio, they started equating noise floor to dynamic range. And later resolution. But with analog, the signal can be heard well **below** the noise floor. And if the signal is noisy, it can be heard below that noise too. As I said, noise is noise......
"> > Otherwise, for example, nobody would be able to communicate on an airplane.
"What's the relevance?"
If the analog noise floor was truly equivalent to "running out of bits" in the digital domain, equating the so-called "limits on resolution", it would be impossible to communicate on an airplane in flight, whose ambient noise is well above the dB levels of people talking on the plane.
