LCAST Surround

MeterPlugs LCAST Surround is a loudness and true-peak metering plugin for checking mixes, masters and broadcast audio. Rather than shaping your sound, it helps you assess playback levels, loudness variation and intersample peaks through numerical readouts, color-coded graphics and a zoomable loudness history display. Support for mono, stereo and surround makes it useful for music production, film mixes and television projects. Presets cover major broadcast standards, including ATSC A/85, ITU BS.1770 and EBU R128, while loudness targets help you prepare music for normalized streaming playback. In hosts that support offline processing, LCAST can calculate integrated loudness, loudness range and other measurements faster than real time. It suits home producers looking for clearer mastering feedback, as well as engineers who need to check longer programmes against delivery requirements.
