How well does Cubase SX resample when importing 44.1khz files in SX set to a higher samplerate?!
"Mike" wrote in message
... 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... http://www.voxengo.com/downloads/ ....or if you can't, then you don't need to worry about the answers to your other questions -- Neil Henderson Progressive Rock http://www.saqqararecords.com |

How exactly is that? 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? 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. squig ˜¼ |
