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).
