Sample Rate Conversion

[LaurenceConway]

Hi this is a seemingly silly one but what is the result of bouncing a project at a higher sample rate that the one it was recorded in? i did it just now and as it was bouncing the 'converting sample rate' bar did its thing but what is being converted here, surely more samples can not be conjured, so what is the thinking bar doing?

Indeed, additional samples are invented when you sample rate convert.

 

When converting from lower to higher sample rate, samples are made up. When going from higher to lower rates, samples are removed, but the waveform data needs to be re-constructed as well, so again, samples are made up.

I see, thats interesting. Converting to a higher sample rate than that of its recorded wouldn't improve sound quality though would it?

It wouldn't.

What Jope said.

 

There's a saying about what happens to digital media when a file is sample rate converted: "garbage in, garbage out". Sounds cynical but it's not. It's realistic. To put it another way, when you have an original digital file and you change the values of its data by converting it, say, from 44.1 to 88.2, the conversion can't possibly sound any better than the original. If anything, there's the possibility that it might sound a teensy bit worse. Garbage in, garbage out. Or to put it more nicely, perhaps, "great mix in, ever-so-slightly-different-sounding mix out".

yep, thanks
