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 HDSPe MADI FX,
showing sample frequency, lock and
sync status for every input.
The sample frequency shown in the
fields Clock Mode and 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. HDSPe MADI FX displays
the current sample frequency of the
currently used input. This parameter
can then be changed
application's audio

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
Steinberg's ASIO protocol with RME's
ASIO drivers and
compatible programs. When 'ASIO
Direct Monitoring' has been switched
on, the input signal is routed in real-
time to the output
recording is started (punch-in).
