Default How well does Cubase SX resample when importing 44.1khz files in SX set to a higher samplerate?!

Hi,

If you set the samplerate at 48khz in Cubase SX (which is recommended
when you use an Audigy card) or even higher if you card supports 96khz
and you want to import a standard 44.1khz wav file, I believe SX will
ask to resample it, am I right?


Yep.

How does that work?


It just resamples it/converts it... what else is there to know?

If it resamples during import, how good is the quality of the resampling

process of SX

Not too shabby, IMO, YMMV.

or is it better to use an external program like Sound Forge to resample
all 44.1khz files to 48khz first, which would be time consuming?


Using an external conversion process would be more time-consuming by
nature, but we're also talking only a few seconds difference per track,
however. OTOH, I also don't think that SF's conversion is any cleaner than
CubaseSX's.

How good is the quality of the 44.1khz to 48khz resampling of Cubase SX?!


IMO, it's adequate in most cases that I've used it in, in any event. See
fine print coming up near the end, though.

When Cubase SX resamples to 48khz, does this affect the quality of the
audio file in any way, like is there any noise or a little bit of
distortion added or something to the file when resampled or does the
quality of audio the file stay completely perfect after SX has resampled
it to 48khz?


Whenever you resample on any application, there might possibly be 'some'
errors - the errors that are most common are rounding errors that result by
going from non-evenly-divisible numbers... like 48k to 44.1k, for example.
Going from 88.2k to 44.1k is less likely to result in rounding errors
because it's evenly devisable, as compared to going from 48k to 44.1k. Guys
like Arny may also have some input on this topic.

Anybody here with an Audigy 2 who can tell or if you have another card,
could you do a small test where you set samplerate in Cubase SX to 48khz
and then import a 44.1khz wav file and let Cubase SX resample it on
import. Does the audio quality remain the same?


It shouldn't have anything to do with the card, really... those
calculations are done internally.

Here's the fine print I mentioned befo Go here if you want to check out
the best (IMO, of course) samplerate-conversion utility on the planet...
look about 3/4's of the way down the page for a free app called "r8brain".
You CAN hear the difference...

....or if you can't, then you don't need to worry about the answers to your
other questions

Just an aside, if you record at 44.1kHz into the Audigy from an external
source, the audigy will first sample it at 48kHz, then resample it down to
44.1kHz for you on the fly. It makes a royal dogs dinner of this, loses sync
within about 30 seconds, and sounds dire.

When you listen back to files at 44.1kHz (say, if you are using samples you
downloaded or imported from a cd, etc) with your audigy, it does the
reverse, it ALWAYS resamples them 48kHz on the fly, and then outputs the
48kHz. This is done automatically on the soundcard without user involvement.
This sample conversion is again very low quality in relative terms, although
does not lose sync... normally...

As a result, if you resample your 44.1kHz files to 48kHz before playing
them, regardless of whether it is soundforge or cubase you use to resample,
you will probably find that they sound BETTER than they did before
resampling took place. This is because the audigy does not have to resample.

Try it.

Use a cd ripper program to rip a Wave file (not mp3) of a song from a cd
that you consider to have very high fidelity. This will be at 44.1kHz. Then
use soundforge to convert a copy of it to 48kHz using it's highest quality
converters. Then listen to both files through your audigy, I would
anticipate that the 48kHz will sound a bit clearer.
