ADAT specifications: only 16 bit or also 24 bit ?

Hi all....

I want to buy a 24bit Harddiskrekorder with an ADAT-Interface and integrate it in my PC Pulsar Setup.

When I want to get the data from the SCSIharddisk (of the hd-rekorder) into my PC (e.g. to edit the music in Logic, Cubase, Wavelab or whatever) I do not want to use a SCSI-Interface for that, because of the problems this can cause concerning PCI-Bandwidth; instead, I want to push the play-button of the harddiskrecorder and re-record the music on 8 channels (4 stereo) on my PC (in Logic).

Question:

Does this procedure lower the sound-quality, because of the specifications of the ADAT-Interface, which is only 16bit resolution ?

Or can I also record 24bit using ADAT ?

thanks for your help

regards

thilowski

Snoopy; Was that a desperate cry for clarity?

To elaborate on what subhuman said, adat can transfer at 24 bit quality. Providing both pieces of digital equipment support it, and are set correctly to do so.

Sorry thilowski to spoil what was such an elegant answer from subhuman.

24bit is really ok, yeah....

btw. I have some questions and it would be nice if you give me some short hints

1. would you prefer a digital mixer like the yamaha o1v and recording on a laptop with a rme hammerfall multiface cardbus system and samplitude (or another multitracker),

OR

doing the mixing via a faderbox (e.g. Doepfer PocketFader with 16 alps-fader) and recording with a standalone hdd-recorder -
what setup is more reiable ?

2. what setup gives you the bestsoundquality ?

(I was thinking that recording with samplitude would give you 32bis float (or at least 24bit for audio), with logic you have 24bit/96khz, if you want that, whereas on some midprice hd-recorders or adat-tape-recordes you get "only" 20bit.

3. what system gives you more recording-time at once ?

(when I record a live-gig I would like to record 4 stereo tracks (8 channels) at once for a time of about 2 hours (better more)) - is this possible with hd-recorders of the midprice-section (up to 1.500 Euros / Dollars) - I heard that the formatting process of some hd-recorders doesn´t allow you to record 2 - 3 hours and that you would have to make a break to start a new record process (in a live-club-situation - at least here in frankfurt/germany on the goa-parties you do a gig of about 2-5 hours

ok.. enough for now..

thanks in advance for contributing your thoughts

1 Multiface. It is a mixer! Have a look at your dealer. The box is just the in/out. (8)
Record via RME Mixer (Software, replaces the tiny Windows built in "mixer") into Multitracker with your Laptop.
2 32/96 is enough? Then Multiface with Samplitude or any other 32/96 application.
3 A 80 GB Harddisk should be sufficient for a start and a few gigs.
Happy recording
Micha

I once recorded 8 hrs, one stereo track 16bit/44.1kHz. The file recorded fine, but it was too large for FAT32.
Can you get it on NTFS? Don't know how harddisk recorders work, but a pc with NTFS formatted disk should do the job.

After the 8hrs recorded nicely, it was a big disappointment to see the file was useless!

Maybe do a try-out recording / simulation before you do the real thing...

The thing is even when you get it onto ntfs what are you going to open it with?
Wavelab has a 2gb limit.
I think cool edit will do it, I remember working on a 4 hour file without too much trouble
