vinyl to digital
 
Are there any freeware packages that can get 24/192 or 24/96 data rates from vinyl playback?

Further, are there any lossless compression packages that can reduce the datarate without losing any of the sampled signal.

Finally, if we start with a high datarate and then lossy compress it to a manageable datarate, can we detect that replay performance is better than CD's 16/44.1 Can this been done with freeware?

I use audacity: http://audacity.sourceforge.net/
the interface is fairly easy to use and it's free :) of course you need hardware that will support your data rate

try flac: http://flac.sourceforge.net/ it will reduce the file size without reducing datarate (which i think is what you want). reducing datarate is lossy. I haven't used flac much but i've read some good things about it.

Hi!
Why don't you try soundforge-sony software, or wave Lab lite- steinberg?Also you can find Clean studio pinnacle to clean up vinyl rec., noises...etc.
I made many recordings from vinyls on hard disc on wave format.wav, the best, and than burrned to audio cd.
Ps:I used a quite poor and cheep turntable, that's what i have now and terratec phase 22 sound card.
result: very good natural sound, but still not like Vinyl played at the real time.....analog playing.

does FLAC work beyond 16/44.1 datarate?

There is no point in saving my vinyl collection to the useless CD standard. Remember that red book standard based on the available computer power way back in the 70's. Would you use a computer that old now to surf the web or ADC an analogue source?

it works for example:in 24-bit/96 kHz

thank you.

My pleasure

So as a followon, what are people using these for sampling in terms of hardware?

i have a creative audigy 2 nx. it's an external box rated at 24-bit/96kHz. quality of vinyl rip is not bad, although i need a better phono stage so i haven't ripped many yet. nothing magical so far either.

I guess it depends on what you are psychologically happy with, I suppose. But what you are psychologically comfortable with and what actually gets the job done can often be two completely different things, eh.

In terms of demonstrated coloration, no audible degree of it existed with good quality ADC->DAC process at 44.1kHz/16 bits PCM in the extended JAES published and peer reviewed *test of recent time where almost a year of research(DBTs in all manner of high end systems and studio monitor systems with many different expert listeners) results in no significant difference found with original high resolution audio recordings vs. the high resolution recording analog output put through the ADC->DAC process using a 44.1kHz/16 bit unit.

I highly doubt vinyl has anything special to offer over high-res recordings that would make the tests come out any differently if they had used a high quality turntable and cartridge instead of hi-res digital sources.

Don't get me wrong, I love vinyl for what it is, and I have invested a considerable amount of money into a very high quality turntable for my own use. I'm just trying to give perspective. Assuming the sound card used has a high performance 44.1kHz mode, it does not appear there would be any issue using this sample rate to capture the vinyl playback. Perhaps use 24 bits extended bit depth for initial recording for purposes of editing/processing the tracks is a good idea and then reducing to 16 bits with the appropriate dithering for the final version.
