Im reading about audio cards and find two interesting things is that one mentions Snr 122db and the other model shows 122 SnR. so what is the difference between these two?
 
Solution


Ideally you want something with both a good SNR and a good DNR, although of the two, I will take DNR, as poor DNR makes everything sound a bit flat and boring; poor SNR only really rears its head at eardrum breaking sound levels.

But then, I am from the LP generation, I am used to a bit of hiss.

S/NR = Signal to Noise Ratio, it gives you an idea of how much hiss you will get at any given amplitude.

DNR = Dynamic Range, and is the difference between the lowest and loudest sounds the device can handle; ie from the noise ceiling to the maximum it can handle without distortion.
 
so if the specifications mention DNR on one product and SnR on another one and show 122db wich is better or is it a trick to sell a product that seems very the same
 
They are two totally different measurements.
There is no way to compare products with different measurements.
Maybe if you posted the devices you are considering, we can help you decide the better component.
 


DNR (Dynamic Noise Reduction) is the process of removing noise from a signal in real time.
 


Unless I'm reading this horribly wrong, both products seen to be promoting a Signal-to-Noise ratio of 122dB. Not sure where DNR is coming into play here based on what you posted.
