LCAST Loudness Meter

LCAST makes it easy to take loudness measurements and supports the latest loudness standards, ATSC A/85, EBU R128 and ITU BS.1770-2, which aim to eliminate loud commercials and improve audio quality in broadcast. Two versions are available: LCAST Stereo for $199 and LCAST Surround for $399.

If you are working with mono and stereo programmes, LCAST Stereo gives you everything you need to ensure your programmes meet broadcast requirements:

- support for ATSC A/85, EBU R128 and ITU BS.1770-2;
- loudness history plot, which shows you how loudness loudness-- momentary, short-term and integrated--changes over time (up to 24 hours);
- loudness range display;
- custom loudness variance measurement, which shows you how dynamic your audio is;
- True-peak metering for each channel;
- overload indicators with adjustable threshold;
- gated and un-gated loudness;
- custom color regions in the history plot.

LCAST Surround includes all the same features but gives you surround sound, up to 5.1 channels. It also includes loudness logging, a powerful feature that allows you to export all loudness data recorded by LCAST into a CSV file, which can be opened in a 3rd party app like Microsoft Excel. This gives you the flexibility to create custom reports, perform additional processing and integrate LCAST into your workflow.
