NuGen Audio VisLM – Loudness Meter AAX | RTAS | VST

Practical Applications - Loudness normalisation for the whole production & broadcast chain

Loudness normalization introduces a common reference point for all stages of audio production, allowing audio professionals to remain in control of audio quality and meet current & proposed legislation.

Post production

Objectively measure constituent loudness values
Achieve average loudness harmonization from differing sources
Balance music/dialog/special effects

VisLM simplifies the process of harmonizing dialog, music and sound effects by allowing objective comparison of both loudness and loudness range (a measure of the consistency of signal loudness), making the process of loudness harmonization more rapid and reliable than ever before. As well as assisting in the balancing of different aspects of the soundscape, VisLM can be used to quickly match recordings in different settings (eg. documentary production, film soundtrack work) creating a more consistent, harmonious listening experience.

Mixing | Mastering

Take control of audio quality at source
Avoid 'level shifting' further down the broadcast stream
Produce consistent masters
Match average loudness across compilation productions
Preserve audio fidelity using True Peak level meters

With the introduction of recent legislation and the adoption of new international standards loudness metering has become a requirement for broadcasters the world over. To comply with technical requirements, audio that does not meet target loudness requirements will be 'level shifted' to maintain the channel average loudness profile, which with current leveling practice will mean that the audio is will probably be 'turned down'. To avoid this, loudness control and normalization should be adopted.

Broadcast | Transmission

Harmonize program content
Achieve loudness consistency within channel
Maintain loudness consistency across channels
Meet recent legislation and adopted standards
Manage live broadcast levels rapidly and objectively
Consistently balance music/dialog/special effects
Perform station monitoring and historical diagnostic

Loudness metering finally allows broadcasters to achieve consistent levels of average loudness within and between channels. It is possible to measure and harmonize the relative average levels of all types of program material, be it music, live broadcast, dialog, advertising or effects leading to a better listening experience and complying with recent legislation (CALM Act etc.). VisLM is also capable of providing detailed historical log files to allow station postmortems (eg. checking the consistency of shared services, locally inserted content etc.)
