Multi-format loudness metering

The most fundamental question in audio production, how loud is it? Simple and yet elusive, with loudness inconsistency and incompatibilities present every day in broadcasts across the world.

With detailed, objective loudness measurement, history and logging facilities, VisLM provides a simple, ITU, ATSC and EBU standard compliant way to measure, compare and contrast loudness during production, broadcast and post production, on the fly or for entire sections of audio.

VisLM introduces several essential parameters for audio measurement.

True-Peak level metering (inter-sample accurate level monitoring)

Loudness Range (to help decide if and how much dynamic compression to apply)

Momentary 'instantaneous loudness' for mixing by ear

Short term loudness (3 second time window)

Program Loudness (long term integrated loudness measurement)

Practical Applications

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.)
