During the Loudness capture, you may now toggle the capture between ‘Start’ and ‘Pause’. The

overall resulting loudness readings will express the summarized capture of all audio above -

70dBFS from the last Reset.

Hitting ‘Reset’ will clear the loudness Capture and measurements.

Overall, the Start-Pause mode allows you to manually start and stop the capture during breaks

or audio that you do not wish to consider in the overall loudness readings.

Auto-Start Mode

The Auto-Start mode, has controls and options similar to those of the Start-Pause Mode, with

the addition of an automatic start/reset facility triggered by the audio level.

More specifically, if the audio is higher than -70dBFS, the Loudness Capture is automatically

started, as well as being automatically stopped and Reset when the audio drops below -70dBFS

again for more than 2 seconds.

This mode is particularly handy when working with smaller bits of audio, and frees you from

having to manually reset the loudness capture every time you want a new reading.

Auto-LTC – Loudness Automation

The Auto-LTC mode automates the Loudness capturing based on incoming LTC / SMPTE

timecode.

This is an extremely efficient audio production mode, as it features instant recalculation of all

Loudness capture results when editing even tiny bits of the audio clip.

Imagine wanting to measure and adjust loudness for an audio clip of 5 minutes, but really only

altering the audio in a section of 30 seconds. This would normally mean that you would have to

allow the Loudness measurement to go over the entire 5 minutes after every edit.

With the Loudness Automation feature, the PAM PICO TOUCH automatically identifies what

section of the audio is being altered based on the incoming timecode and instantly recalculates

the complete loudness result.

Please see the ‘Loudness Automation’ section for further details on how set this up.

Loudness Display

The Loudness parameters available for display are the following:

 Momntry – ‘Momentary Loudness’

 Shorttrm– ‘Short-term Loudness’

 Integrt – ‘Integrated Loudness’

 None – Meaning no Loudness Bar graph displayed

 Momentry+Shortterm – both readings alongside each other

Note: As per the BS1770 standards, audio below -70dBFS is not included in the overall

loudness capture. This is to avoid that breaks or silence in the audio undermines the

loudness readings.
