 Ok, compared to the card, 79$ are a lot, but it is cheaper than the Midiman
 Dio 2448 and I think the DIO 2448 is not supported by Linux. Do you know
 another card with digital in/out cheaper than the 4DWave NX including the ST
 DBIII module?

 You also need the NX DB II at $24 I believe, which raises the price
 of digital-in to $103.

You are right! See

Have a look at http://www.rme-audio.com/english/digi32/digi32.htm

The RME Digi32 is discontinued, so maybe you can get it very cheap. I have
no idea if it can copy bit by bit.

If you're talking about the fixed samplerate of 48 kHz, that's

Check de.comp.audio for details.

With MD bit to bit copy is not possible, when you are recording, since MD
compresses music, but if you use your MD-recorder as A/D-converter, it could
be important.

Let's assume the following:

You have a song on a DAT-Tape (DAT does not compress) and you copy the song
to the PC as a wave-file, copy it back to DAT and then back to the PC as a
wave-file again, but with another name. If you compare both wave-files the
files should be identical bit-by-bit. With most cheap-soundcards this is not
possible.

The reason for the problem is that 44.1kHz signals have to be converted to
48kHz and back to 44.1kHz with "normal" soundcards, because soundcards works
with 48kHz internally. (I hope this is exact enough, what I wrote)

The question is, if you hear the difference.

RE: MD: Linux S/PDIF soundcard

2000-01-26 Thread Martin Schiff


Ok, I did some research and understand what bit by bit copy means, but how
does it apply to MD? The only way to do a bit by bit copy of anything is to
have software that allows you to do it. That means you would have to be
using some sort of data drive to copy a disc image of a MD. When you play
digital music from a computer wav file or mp3 and record it on a minidisc
through a Toslink or coax connection, you are getting a bit by bit copy of
the music, no matter what digital card you use. That's the definition of
digital storage. It's just 1's or 0's. If there were missing bits, there
would be obvious dropouts or digital noise. Even if there is a problem with
the source data, it is possible through error correction to reconstruct the
bits as they should have been, so you can get a correct digital copy anyway.
I really can't see why anything else would be important.  Please enlighten
me.

 Yes. The plus of the NX is, that there should exist a solution with Linux.
 With Win you have the 48kHz problem too.

Actually, I was told that the 4DWave NX chip can output in 32 and 44.1 kHz
as well, just the drivers are locked at 48 kHz. I wonder if that is true.
Now since Trident has stopped any involvement in sound hardware (I think
I read this somewhere) you can probably forget about this showing up in
Windows anytime soon. But since the Linux drivers are open-source, perhaps
it can be implemented ?
It probably doesn't matter, I guess it wouldn't improve the quality of
MP3 - ATRAC transfers at all. :)

 What exactly IS the DIO 2448 ?

http://www.midiman.com/new.htm

DiO 244824 Bit/48 kHz PCI Digital I/O Card

The DiO 2448 PCI Digital I/O Card combines Coaxial and Optical digital I/O
with stereo analog outputs at a remarkably low price. It's perfect for
interfacing to S/PDIF-capable equipment such as DAT machines, MiniDisc
recorders, dedicated audio converters, and more. In addition, the built-in
D/A converter provides analog audio output for monitoring incoming digital
audio. Plug your CD-ROM or CD-R to the internal analog or digital connector,
and use the DiO 2448 as your Windows Sound System card.

Features:
€ 2-in, 2-out 24-bit/48kHz full-duplex PCI audio interface.
€ S/PDIF inputs and outputs on coaxial (gold-plated RCA) and optical
(TOSlink) jacks.
€ Stereo analog output on gold-plated RCA jacks (consumer signal levels).
€ On-board headers accept analog audio from internal CD-ROM players.
€ On-board header accepts digital audio from internal CD-ROM players.
€ D/A converter may be used to monitor digital input or output.
€ Digital input may be bypassed directly to digital output (³audio thru²
mode).
€ Supports 44.1kHz and 48kHz sample rates.
€ Windows 95/98 drivers.

Minimum System Requirements:
€ Windows 95 or Windows 98
€ Pentium 200 Mhz
€ 32 MB of RAM
€ UDMA EIDE or SCSI hard disk recommended

 And while it might still be cheap,

 it would probably be easier to just get a Live! (no pun intended,
 honestly !) where you have to deal with only one bracket.

Easier, yes.

 And you
 have confirmed functionality of both SPDIF directions

but no bit-by-bit. (AFAIK)

 Actually, I was told that the 4DWave NX chip can output in 32 and 44.1 kHz
 as well, just the drivers are locked at 48 kHz. I wonder if that is true.

The only drawback is ALSA support is in the TODO, and it doesn't

The good news is that the card is being sold refurbished by TB, at
