UPDATE - Now for Pro Tools!

When you purchase LCAST, a Pro Tools version is now included! It runs on Mac & Windows with Pro Tools 10.3.6+ or 11 and is 32/64-bit compatible. Many of you have been patiently waiting for this... Now it's here :) Enjoy!

Simple loudness metering

LCAST makes it easy to take loudness and true-peak measurements. It supports all the major loudness standards and has easy-to-use presets for the most popular ones: ATSC A/85 (CALM Act), ITU BS.1770-3 and EBU R128. Mono, stereo and surround formats are all compatible (surround only available in LCAST Surround). Use LCAST with Logic, Final Cut Pro X, Soundtrack Pro, Cubase, Nuendo, Reaper and more. LCAST has everything you need to create broadcast-ready audio.

The LCAST advantage

LCAST is the perfect blend of precision loudness metering, ease-of-use and beautiful graphics. It passes all EBU compliance tests, measuring well within required tolerances. Quite simply, LCAST gives you absolute confidence that your audio meets broadcast requirements. The interface is a simple, uncluttered design with tool-tips that get you acclimated quickly--the LCAST Guide and our online tutorial videos fill in all the details. The graphical displays are so crisp and readable that you'll want to have LCAST open all the time.

Broadcast and beyond

LCAST is the ideal choice for making your audio broadcast-ready, but its usefulness extends beyond broadcast. Whether you're creating audio for video games or the web, movie trailers or commercials, LCAST will help you achieve consistent loudness levels that your listeners will appreciate.

A history of loudness

LCAST's primary display, the history plot, shows you a timeline of your programme's loudness and allows you to quickly spot loudness peaks and valleys. It acts like a personal video recorder (PVR) for your audio, recording up to 24 hours of loudness history. The visual display makes it trivial to identify portions of your programme that need adjustments. This solves the problem of identifying loud commercials, quiet dialogue and much more.

The history plot displays all standard loudness measurements: momentary, short-term and integrated loudness. In addition to that, LCAST features a custom variance measurement that gives you an idea of how dynamic your audio is. Each measurement can be toggled on and off so that you can focus on what is most important to you.

True-peak metering

LCAST's true-peak meters accurately detect inter-sample peaks and warn you of potential clipping. It does this by quadrupling the signal frequency (internally) and interpolating between audio samples. This process catches overloads that other meters miss.

Logging loudness

LCAST Surround gives you the option of exporting loudness data to a CSV file, which can be opened in a 3rd party app like Microsoft Excel. All loudness and (per-channel) peak measurements can be exported. This gives you the flexibility to create custom reports, perform additional processing and integrate LCAST into your workflow.
