Configure InstaRecorder

Setting the DigaSystem parameters for the InstaRecoder has the following sections:

Each parameter is described in the complete list.

Audio Format

The Audio format is the one used for all recordings in InstaRecorder.

It specifies the resolution and the sample rate.

Parameters:

• Resolution
• SampleRate

Audio level scales

The Audio level scales can be configured separately for the faders and the level meter, which shares one scale with the level trigger.

Each scale value to be displayed can be defined. They can be represented in logarithmic or linear scale.

Parameters:

• LinearDbScale
• Segments

Recorders

Any amount of recorder strips can be defined to appear by default.

Parameter: RecorderCount

Configure each Recorder

Each Recorder gets a set of parameters defining the defaults for device, channels, DigaSystem table and title:

Its parameters are placed in a sub-folders Recorders\Recorder_<x> (<x> subsequent from 1 to the number of recorders), which contains:

• Device
• Table
• Title
• a sub-folder Channels with one key for each channel
  • CH<x> (<x> is the indicated channel number)

Automated Start Trigger

The Start Trigger mechanism is used to automatically start a recording when the audio level of a source device reaches a certain level for at least a defined amount of time.

Parameters:

• StartSignal\LevelDb
• StartSignal\DurationMs

Effects

Effects have to be Global

Effects have to be defined in the Global\Default namespace!

To apply effects to your recording (both for the monitoring and the output of the recording in DPE.

A sample parameter file is available as road-clients/docs/DPE-Parameter-samples/InstaRecorder_Effects_examples.par 

The configuration keys are the following:

• Effects\SaveRawAudioWhenApplyingEffect
• Effects\FreezeEffectWhileRecording
• Effects\My Effect\Label
• Effects\My Effect\FilterSpec
• Effects\Another Effect\Label
• Effects\Another Effect\FilterSpec
• Effect\ ...

Each subfolder of the InstaRecorder \ Effects folder will be an effect, with a label and a filterSpec (see more details and example in the table below)

Because applying an effect to a recording could incur data losses (if the effect renders the output audio file unusable), InstaRecorder will save a RAW audio file (without effect) alongside the primary recording (with the effect).

This behavior is controlled by the key InstaRecorder / Effects / SaveRawAudioWhenApplyingEffect which defaults to true.

Be aware that setting this key to false could incur data losses.

See more information below

An effect can be selected (through a dropdown) by the user, and can be switched on/off before the beginning of the recording.

This behavior is controlled by the key InstaRecorder / Effects / FreezeEffectWhileRecording which defaults to true.

If the parameter is set to true, the effect will be fixed when starting the recording, i.e. when click on the "Record" button.

If the parameter is set to false, the effect can be switched on/off while the recording is created, but the selected effect cannot be changed.
