9.5 Digital Recording

Unlike analog soundcards which produce empty wave files (or noise) when no input signal is
present, digital I/O cards always need a valid input signal to start recording.
To take this into account RME included a comprehensive I/O signal status display (showing
sample frequency, lock and sync status) in the Settings dialog.
The sample frequency shown in the Settings dialog (see chapter 8.1, screenshot Settings) is
useful as a quick display of the current configuration (the card itself and all 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 required input, HDSPe AIO Pro displays the current sample frequency. This parameter can
then be changed in the application's audio attributes (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 24).
An automated control of real-time monitoring can be achieved by Steinberg's ASIO protocol with
RME's ASIO drivers and all ASIO 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).

9.6 Analog Recording

For recordings via the analog inputs the corresponding record device has to be chosen (AIO
Analog (x+x)).
The input sensitivity of the analog inputs can be adjusted via the Settings dialog to meet the
most often used studio levels, see chapter 22.1. The level of the input signal, and if it is too hot
or too low in level, can be checked via the input level meters in TotalMix FX.
