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

AES, 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. After selecting

the correct input, HDSPe AES

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).
