FLUX:: Elixir

What FLUX:: Elixir is
FLUX:: Elixir is a true-peak limiter plug-in for immersive audio productions, including Dolby Atmos workflows. Its output conforms to ITU-R BS.1770 and EBU R128 norms, and it supports up to 32 channels at sample rates up to 384 kHz. Limiting can be divided across as many as 12 stages. With a compatible DAW or host, its 64-bit floating-point processing supports an end-to-end 64-bit audio path. Two parameter slots allow morphing, with the slider available for host automation. Presets include true-peak settings for YouTube, Spotify, Apple Music, and Netflix; input and output gain range from -12 to +12 dB, and true bypass is included. Listed host formats include VST3, Audio Units, AAX Native, AAX DSP, and AAX Venue; VS3 is available only from Merging Technologies. It supports Windows 10 or 11 (64-bit) and macOS 10.14.6 Mojave or later, including Apple Silicon universal binaries for M1, M2, and M3. Use requires an iLok.com account, though machine authorization means no USB Smart Key is required. A 30-day full-featured trial is available. The listed perpetual license costs $149, paid once.
