Topic: Sony Md Recording quality

[hoobash]

I got a sharp sr60 I am selling

[porphyry]

To me, it sounds like it is not lossless.

well to everyone else it sounds like it is lossless.

“Hi-MD” compatible products enable users to enjoy the recording and playback of high-quality sound, close to the quality of commercial audio CDs."

thats all just sony marketing bullshit. from what i understand, Hi-MD recorders will have a whole range of different bitrates and quality levels, including the lowest, 64kbps, which will sound shit to anyone who knows what to listen for but will convince the average man on the street that it is, as sony tells them (and just what other corporations say about MP3) "near CD".

in other words, the Hi-MD recorders will do lossless and lossy stuff.

"close to CD quality."  if it were lossless, then it would say "IS CD quality," but it doesn't.  So that is where I am confused.  Nowhere on the sony spec sheet does it say "TOTALLY FOR SURE NO DOUBT THIS IS IS IS CD QUALITY."  All it talks about is the awesome the new ATRAC3plus COMPRESSION and how it is really cool that you can format a standard 80MB MD into a 300 MB Hi-MD format, etc etc.  I've looked, so if you can kindly point me in the direction where it says Hi-MD will record uncompressed 16/44.1 files, that would be awesome, because for some reason I don't think the hearsay you preach is true, imnsho

Here we go again.

PCM is commonly known as RAW digital, in other words, uncompressed.  You can record 1h34m on a 1GB disc.

...and standard MD's are 140MB, not 80.  They're 80 minutes.

[twatts (pants are so over-rated...)]

I may be wrong, but I thought I read that none of the Hi_MD have digital outputs, that anything recorded lossless cannot be transfered as such.

I have no idea, I think the money is better spent on a Nomad 3.

FWIW< if i were to stealth, i would use the v3+backback on my back, IF i could get all of that in the doorr that is, but if it were open taping, and i wanted to be stealth, id do it this way, w/ some 1290-HC's on the pole or in hat;-)

one of these days ill give it a try

[Sean Gallemore]

the numbers aren't adding up for me

700MB = 1H20M of uncompressed wav

on hi-MD

1024MB - 1H34M of so-called uncompressed wav

so if these 2 wav formats are the same, why does it take an extra 300+MB to record only 14 more minutes than a standard CD?

[Sean Gallemore]

oh yeah, thanx, joe, for pointing me to some hard info

maybe the HI-MD does 24/96

[Sean Gallemore]

did sony say it will start making products that don't randomly have dropouts in lengthy wav recordings.  You know what I'm talking about, yeah, those.  The .1-.3 dropouts riddled on every disc I've ever recorded (except one with my Sharp)

damn, that sux schwill, never knew that, another reason why i never owned one

[joemango]

Schwill:

Glad to provide the info.

The transfer issue is still a tough one.  Supposedly you will not be able to do a  usb transfer to your PC of a digitally recorded item..  They say that it is possible to do so with a recording made with the MIC input.  I wonder if they are referring to SCMS.

We'll only really know wehn someone actually gets their hands on one in April and does some experimenting.

Unless it does digital transfers of digital recordings, I won't buy one, and I'll keep my JB3, thanks.

Actually, 80m of uncompressed 16/44.1 takes up exactly 786432000 bytes.  You can store 700 MB of DATA on a CD-R, but writing DATA to the disc requires it to have subcode, allocation and checksum formatting, which requires extra space on the disc.  Audio is encoded with a minimum of extraneous data, so you can fit more than 700 MB of audio on a disc.

To see this yourself, rip a disc that has a full 80 minutes of audio on it, and you will see that it takes up much more than 700 MB.

I suspect that there is a fair amount of formatting going on in the Hi-MD, (perhaps encyption, maybe error-correction checksums) so there you have the difference between 1024 MB and the 924057600 bytes contained in 1h34m of uncompressed audio.

I have no doubts whatsoever that it can record straight uncompressed audio.
