1-bit 5.6 mHz recording-what is it?

DelCallo wrote on 11/23/2007, 2:42 AM
I recorded a three hour concert of classical music a couple of weeks ago. I am anything but cutting edge, possessing neither the budget nor the inclination to keep up with the latest/greatest. So, as is my habit, I "lugged" my XPC PC, screen, Tapco 6306 mixer, and an old TEAC cassette recorder (for backup purposes) to the venue and recorded the event.

After the concert, a parent of one of the performers came up to me inquiring what I was using to capture the performance.

We had a Thanksgiving Day bash yesteday where all those and a large number of other professional musicians were invited to join us for dinner. This parent came, as well, and showed me his newest toy - a Korg MR1000 digital field recorder.

The manual (and the website) go on about how it records in 1-bit audio formats - DSDIFF, DSF, WSD: 2.8224 MHz @ 1-bit
5.6448 MHz @ 1-bit

It also offers typical wave format with which I am familiar.

Advertised at around $1300, it isn't cheap, but certainly not out of reach.

My questions: what is this new format (maybe it's not new)? Can someone explain how it works - 1-bit 5.6 can be converted losslessly to standard wav formats that use higher numbers to describe resolution/bit depth?

Will my live recording results be enhanced by such a machine, or will I do just as well using my large, heavy rig recording standard wav files at 96/24?

Thanks for any responses.

Hey Del,

DSD (think SACD) has been around for awhile, it's a great format but never really caught on. This thread might be helpful.

Thanks for the reply and links to interesting reading.
Think I'll have to give the Korg a try and see if I can hear a difference.

Be aware that DSD editors are rare and expensive. They are all hardware based, though there is an extension to the ASIO standard that permits i/o.

Thanks, ...PCH.
So, if I picked up one of these machines with no intention of investing in expensive editors, would the resultant work flow negate the advantage (audible or theoretical) offered by the format?

I'm guessing that, to edit with Vegas or SF, I'd be converting to WAV, so, is there still an advantage to the DSD format for me or not?

I'm not certain I want to relegate my trusty PC and mixer board, but that Korg is a temptingly light and small package. If it actually offered me improvements, then, it might not be such a bad idea.

OTOH, I don't want to spend $1,200 or so just to replicate capabilities I already have. That's why I figured it best to post questions here.

Thanks for the advice.

I'm kind of dumfounded that you would consider lugging a PC and monitor to a LIVE concert "trusty" or preferential to a device which has the sole purpose of faithfully recording audio in a arguably superior archival format. Buy the KORG or any of a number of high quality location recorders (Sound Device 7xx series etc) and keep your computer and it's OS at home! :)

Don't be dumfounded, tomaras. I used to lug an 85 pound R2R recorder equally specific to the sole purpose of faithfully recording audio in an arguably superior archival format. Obviously, until learning of and posting questions about the Korg, I had not heard of it before, and, hence, would not have considered purchasing it by definition.

Obviously, having learned of it, I am very interested in its possible relevance to the work that i do.

Lugging a small form factor PC, monitor, keyboard, and mixer to a live venue is still far less taxing on this aging body the lugging necessary to incorporate one of my R2R's in the mix.

Oh, and I don't simply consider lugging the PC, etc. I am, at present, left with no more efficient choice, as that is the smallest package (with the highest capability) that I have at the moment . . . and capable it is . . . virtually unlimited recording capacity at high sample rate/bit depth that gives wonderful results.

For me, this compact PC makes much more sense than other dedicated recording setups available of which I am aware.

The Korg, on the surface, seems to offer even better potential fidelity in a much smaller package.

Garnering info on that machine, it's pros and cons, was the purpose of my response.

Until I am satisfied that the Korg makes sense, I take comfort in the fact that I can make very high quality recordings lugging my present equipment to live venues.

. . . and, FWIW, no one will come up to me following my taping of some concert using the Korg and ask me what equipment I'm using . . . something that almost always happens when I'm sitting at the back of the space running my little PC (most folks don't recognize it as such) and either a R2R or Cassette unit for back up.

Basically, I do whatever it takes to have capable, if not the latest, equipment with me in order to capture a version of the performance that will result in a CD/DVD with which the client/performer will be pleased.

It is what it is . . . no reason to be dumbfounded.

I would be more concerned with the mics, mic pre amps, A/D converters than a format or particular machine.... within reason.
