12.5 Digital Recording
Unlike analog soundcards which
produce empty wave files (or noise)
when no input signal is present, digital
interfaces always need a valid input
signal to start recording.
Taking this into account, RME added a
comprehensive I/O signal status display
to the HDSP MADI, showing sample
frequency, lock and sync status for
every input.
The sample frequency shown in the
fields Clock Mode and MADI Input
Status is useful as a quick display of the
current configuration of the unit and the
connected external equipment. If no
sample frequency is recognized, it will
read ‘No Lock’.
This way, configuring any suitable audio
application for digital recording is
simple. After selecting the correct input,
HDSP MADI displays the current
sample frequency. This parameter can
then be changed in the application’s
audio properties (or similar) dialog.
It often makes sense to monitor the
input signal or send it directly to the
output. This can be done at zero latency
using TotalMix (see chapter 25).
An automated control of real-time monitoring can be achieved by Steinberg’s ASIO protocol
with RME’s ASIO drivers and all ASIO 2 compatible programs. When 'ASIO Direct Monitoring'
has been switched on, the input signal is routed in real-time to the output whenever a recording
is started (punch-in).
