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 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).
