Sampling-worries

[Cavendish#2]

Hello everybody,

I just wanted to know if it's possible to downsample source-material recorded
with 192khz/24-bit to 96khz/24-bit or even to 44.1khz/16-bit.

If i use a program capable of doing this task in software, would the final quality of the file be as good as a originally in the target-sampling rate recorded piece of music. I'm asking this because i want to save my files in all three mentioned quality-setups (don't ask me why, i even don't know it myself...). So a perfect
method of downsampling would save me the recording in 96khz/24-bit and 44.1khz/16-bit, because I just could edit the 192khz/24-bit by downasampling it twice. Maybe I'm just an optimist...

I've read that 192khz is not perfectly dividable for lower samplings, so i should use a more suitable samplingrate? But this would compromise my silly DVD-Audio scheme (after that, well, world domination, hehe...

)!

By the way, does this downsampling really effect only the samplingrate or can i reduce the bit-resolution without loss of quality (again compared to a originally un-edited recording) as well.

Hope for some encouraging answers

Greetings

IMO, keep your highest bitrate source, and don't even bother converting the rest. During playback you can use a media player like foobar to resample accordingly. And the thing is, resampling algorithms get better all the time. So why digitize for archival purposes and store downsampled copies using 2005 downsampling?

it is perfectly possible to do so.. record, edit and apply effects in the highest resolution you can get and then convert down as you need.. you can use SSRC resampler for that task and obtail great results..

in fact, you are sampling at the same speed wheter you choose 48 or 192kHz.. the only difference is that the ADC's digital filters will downsample to 48 or 192.. you can do that in software anytime..

Hi Glassmann,

sounds encouraging, but I'm still a bit scared ( frightened little me

)
to sacrifice quality for idleness.

Isn't there a difference between the two approaches (native recording or downsampling), maybe a tiny, neglibile one, only to prove with an electron microscope or a crystal ball, but for me as large as the Mount Everest....oh blimey, I've forgotten to take my pills...).

I just don't want to feel uncomfortable later....

By the way, any further suggestions for a good soundcard (usb or FW)?

P.S. I envy you for the place your living, glassman. Prague is just great!

no such difference, you can be sure.. if you're really insane, recording at 24/176.4 is wee bit better for converding down to 44.1 than in 24/192, you won't tell any difference anyway but..

as for Prague: try to live w/o PayPal, Digikey, w/ our postal service (service?) etc. nothin' is perfect boy

but yeah, it's definately a great place to live otherwise

Yeah, but then again, I would have to upsample my material to 192khz to
satisfy my DVD-audio obesession, a most frightful thought for me...

Well, one can't have everything. But you are "improving" every day, I'm
sure (since the bloody communists are history

)
