Recording from LP / analog sources at 24 / 32 bit vs. 16 bit

Hi all,

Been reading posts / articles on recording from LPs & other analog sources using various bit rates.

Some advanced? users suggest using 24 bit (or 32). I guess it depends on what you do w/ the wav files once recorded?

I have an X-Fi Titanium, so is capable of 24 bit, 96 KHz. Recording live music at these settings is one thing, but if recording off an LP, what is benefit of recording at settings higher than the source? If there is any benefit, in what circumstances would you be able to utilize the higher settings?

Along same line of thought, lots of encoding prgms will allow encoding some files - even same format - wav to wav (say, original source was 16 bit) at 24 or even 32 bit & much higher freq than orig. Is there any use in that? I briefly played w/ recording LPs at 24 & 32 bit & couldn't really tell any difference.

Recording from LPs - I'm not sure there'd be any benefit to higher than 16 bit. Also have some "HQ" reel to reel recordings I'd like to record / preserve in best possible way - for now, probably just using stereo. What if wanted to convert the LP / R-R digitized recordings to say, surround sound? Any benefit recording at higher bit / freq rate for that or other future scenarios?

Main concern is preserving these recordings from LP & possibly reel to reel, in best way for possible future changes in technology that may allow altering, better noise filtering - what ever. Right now, I'm just using stereo, but if wanted to convert to surround sound (for instance), etc. Would there be any value for that or other reasons, by recording the LPs / reel to reel now at higher than 16 bit / 44.1KHz? The R-Rs are already pretty old, so however I record them now, needs to be best possible way for anything in the future. They were recorded on about the highest quality tape available, on a high quality recorder at high fps.

Thanks.

recording from lp

I am recording my vinyl to digital so that my family can access it easier. They are intimidated by the turntable!

I use 24/96 for my good sounding lps and 24/44 for those that are compressed. The reason being that I can hear the loss of the better vinyl that is recorded at 16/44, or cd quality. My wife can hear the difference from another room in fact! With my testing in my system, 24/96 is enough, but not too much.

I do not think that cd quality settings equal the "resolution" of my vinyl source! Actually, I am convinced of it given that my wife notices the difference! Try it for yourself, you can rip a record at different quality/data levels and find where the resolution of your system resides. But lest you despair, I have an upgraded Rega P3 with a $500 Grado cartridge, so it is not my super duper front end, it is the inherent resolution of vinyl.

Let us know what you discover, and nice to meet you!

just a bit more

Bob, if you want quality, never throw away data! You could record these at 24/96 and store a copy at that bit rate while you downconvert the files you use. I also have digital copies of my analogue photos, and I NEVER throw away data in the original scan. Get it down to the numbers as large as you can, save the rip, then downconvert to whatever ya need.
