Record 24/96, yes, but inexpensively,
probably not.
Today, laptop recording works most
reliably when limited to 24/48 digitizing
due limitations imposed by hardware
(the USB 1.1 or PCMCIA interfaces) and
software (Windows or Mac OS audio drivers).
Laptop recording at 24/96 or 24/192
will be more realistic when companies
begin to produce portable analog to
digital converters that connect to the
computer using USB 2.0 or Firewire.
If you can record to a standard PC,
then you'll need to employ a PCI sound
I/O card with S/PDIF coax connector to
input the digital signal. The M-Audio
Delta Dio 2496 that costs about $200
is one example.=20
Note that I am not recommending that you
use the PCI card for analog to digital
conversion. The interior of a PC is a
very noisy place from an electrical
perspective, and A/D conversion done
here is likely to have added noise.=20
The (expensive) answer is to employ an
external mic pre-amp and analog to
digital converter, with a S/PDIF cable
that enables you to mount it a short
distance from the computer.=20
High-quality pre-amp and analog to
digital converters capable
of 24/96 operation are expensive.=20
Products in this category include
the Grace Designs Lunatec V3 and
the Sonic AD2K+. Either costs about
$1700, not including the laptop computer!
The Apogee MiniMe is slightly more
affordable at $1500. All three have
S/PDIF digital output to connect to
the computer.
The high cost of 24/96 recording is
one reason why many recordists are
intrigued by the recent announcement
of theSound Devices 722. It's a hard
disc recorder with custom software
plus a high quality pre-amp and 24/96
digitizer, in a package designed for
use in the field, all for about $2,000.
The 722 is scheduled for release in
a few months. For details, see
