Mini-disc Vs. DAT: Is there a real quality difference?

Starting to make video documentaries with digital video and have become obsessed with sound. In particular, getting high quality free sound to layer in the stereo sound track for eventual DV output.

I want to record local musicians for a dedicated sound tracks -- and for crowd and atmospheric sounds such as cheering, wind, fire, rushing water, screech of tires, squeak of sneakers on gym floor etc. Also conversations that I will layer on top of the main mic -- such as individuals in a crowd at a game.

When introduced to the Sony Mini-Disc at local guitar shop, was blown away by the sound with ECM-717 stereo mic recording local fingerpicking guitarist. Great 3-D sense of sound, robust bass, clear treble. Great!

Even better: iLink digital wire to computer. Fifteen hours of querying puzzled tech support later, I realize: Download digital - yes! Upload digital to computer from Mini-disc? No!

Next step: Buy Cakewalk, Monster cables, adapters, get analog upload. Not bad. Say.... 97 percent of initial impression. Trouble is: If I want to make a CD or upload high quality audio file for use in Premiere video editing, Dell sound card is takes mono input.

Still, recording of classical guitar with ECM-mic near sound hole sounds like the best recording I have ever heard. Rich bass, great resonance. Wow. Listen a little longer, start to hear the flaws: Mic picks up buzzes easily. a little trebly.

Wound up buying EMagic external sound card. 24-bit, stereo input now. Nice. But output is marginal on volume level. Start to hear hiss from too-wound-out sound cards, speakers turned up high, barely squeaking by with enough voluime.

Some guys at local sound shop recommend amplifier. I think: Oh no, makes it worse. Another layer of translated sound? Probably loses 5-10 percent of initial quality. What to do?

Another guy says: Aw, you shoulda gone DAT. They upload digitally and the transfer is lossless. The Mini-Disc is cool, but its compression technology can't help but lose some of the sound. You can tell it's bright, but not so rich, eh?

OK. Suck it up and find best price for a Sony PCM-1 DAT and
Sony ECM-M?957 condenser mic. Vow to compare the two. Do NOT want to spend so much extra money.

Just before DAT arrives, another guy at another shop who records professionally tells me: Hey, the DAT is the eight-track of the 2000s. It does not get any better sound than the Mini-disc and that mic is bulky and gets in the way and isn't any better than the ECM-717. In fact, it's worse. The DAT is just an expensive white elephant.

OK. I will test em.

Get the PCM-1. ECM-957 mic. Tapes.

Now for the side by side test. Switch mics, too. Use the ECM with both Mini disc (usual) and DAT (new one) Use 957 with mini disc and DAT.

I think: Big DAT is harder to handle. No anonymity with that darn big new mic and its foam wind cover. More like a bus than a sports car.

Big new mic doesn't pick up as much live sound as the ECM-717 with the DAT nor the the Mini-Disc. Olympic TV with stereo speakers of luge and skating presents a tough test. ECM-717, especially with Mini-disc, cuts to clear sound, picking out announcers voices with sharpness. Sounds a little echoe-ey and tinny. ECM-717 real good at poicking up wide circle of ambient sound with either DAT or mini-disc.

Voices: 957 and DAT more neutral, less bright, not exactly rich.

BUT

Without as many sharp, high trebles, DAT+957 large mic real good at full rich understated complete neutral sound. Yeah, I would pick it for the important concerts. But for quiet quick work, the mini-disc, even without digital upload capability, would be adequate for many uses.

Biggest flaw with the mini-disc+ECM 717 combo is mic noise from handling it. How do i set up a handle that won't set off distracting fingers-on-mic noises? Can't hold my breath and close eyes and meditating to not move fingers on every sound take.

One sound shop guy in town says:

Mini-disc specs EQUAL TO -- DAT.

Another guy says: DAT specs and 957 specs clearly have numbers on their side. It is clearly worth the money.

Sony and Mic $320
DAT and Mic $950.

Who's right? And why?

NOTE to this crowd: I apologize because am starting with NO technical knowledge of audio terms. I do know still and digital video photography and so I use those concepts to figure out issues by myself and for processing all thgis new information information relating to audio. So when I write here I am thinking in terms of parallels to larger-smaller negative size in photography and think similar comparisons might well hold true in my DAT vs. Mini-disc shootout.....
 
DAT is better in quality than mini disc as mini disc uses a lossy data storage system. While mini disc sounds good, better than cassette, it does not equal DAT in resolution. The ATRAC system that mini disc uses throws away a lot of data. Wheather or not the difference in quality will make a difference is up to you. Personally, I can hear the difference and I own both DAT and mini disc. For any critical work, I'd use DAT.
 
A more involved answer :0)

Minidisks are around 16 bit, usually around 15 bit because they use nonlinear converters. Add the compression of ATRAC, which isn't really compression at all, I think the term stripping is more suited. Most DAT's use 20 linear converters meaning 20 bit is exactly 20 bit though some earlier versions are 18 bit because of thermal float. DAT's never throws away data based on some predetermined mathmatical programming.
DAT will always sound better and preserve more audio than Minidisk. I have an MD8 for writing and I can actually hear places where the cymbal decay cuts in and out because the compression found a competing wave form and just throws the data away. The data that I found to get thrown away the most is the data at the LSB, this is where all you siblance lies and removes a good portion of the air and depth, your dynamic range is gone forever. Quality cost money, no if and or butts about it! Go DAT way!

Peace,

Just a thought....

Why not get a standalone Tascam Cd Burner.... Good Quality and Cheap Media.....

I recently saw CDr's for 25 cents a piece....

And I doubt you will hear a difference between 16 bit and 20 bit.... (Im probably setting my self up here)

Flame away:D

YO to the board:

I'll back up the DAT for better sound and I don't know near all the stuff that was presented in the previous posts.

I have an MD8 and it will do decent stuff but compared to the Yam 2816, there is no comparison.

Enjoy learning the technical terms you folks set forth. Every day is a day to learn on this site.

Can anyone tell me if the "digital outs" on my 2816 would be used to send tracks to a DAT? I'm guessing that they would work with the right cables. Right now I'm using the analog stereo outs for some fast patching to cassette tape and getting great sound. As always, I'd like to get "better" sound.

Thanks,

hey Broccoli-colored Flying Insect Person,
your Yammie has COAXIAL digital outs. as long as your DAT (of choice) has the same
configuration of INPUTS, yer all good. make sure bit rate and resolution (and all that)
settings are the same on both machines (i.e. 16 bit, 44.1khz etc). otherwise you might set your house on fire. heh heh. if your DAT only has OPTICAL inputs you can buy a simple COAX/OPTICAL converter (like a Midiman CO2. i have one and it works fine for that kinda stuff) to solve the problem. if you need the converter you'll have to buy TWO cables (one optical, one coax). if you DON'T you'll only need the coaxial. cheers.:rolleyes:
 
Yo Cratinus of the planet Vulcan:

Thank you for the information. I see all these types of things in the catalog but until one has the gear, one doesn't know the real purpose of this cable or that converter.

The material I quick record to cassette tape from the analog stereo outs is soooo much better than anything I ever did on the MD8 that I'm anxious to utilize the digital outs.

I'll get there.

Again thanks for the "new" adjective of "broccoli Green." I kind of like that as green is the color of money too.

Green Hornet:D :cool: :p :p
