Our verdict on FLUX:: Elixir
FLUX:: Elixir is a true-peak limiting plug-in for mastering, broadcast, post-production, and immersive audio work. It is designed for engineers working with stereo through multichannel sessions, including workflows that support Dolby Atmos. Processing extends to 32 channels, making Elixir a focused option for projects where channel count and loudness-standard compliance matter more than a broad suite of mastering tools.
The standout capability is its multistage true-peak processing. Elixir provides up to 12 processing stages, 64-bit floating-point audio processing, input and output gain control, and true bypass routing. Its limiting is compliant with ITU-R BS.1770 and EBU R128, while dedicated presets cover YouTube, Spotify, Apple Music, and Netflix. A/B preset and parameter slots, factory, user, and global preset banks, plus a parameter morphing slider with host automation, support comparative work and repeatable changes inside a host application.
Pricing is straightforward: the Elixir Perpetual plan costs $149 as a one-time purchase and includes a perpetual license. A separate 30-day trial is available, while the product is distributed through the FLUX:: Center installer for macOS and Windows. Documented plug-in formats include AU, VST2, VST3, and AAX, and licensing requires iLok. Elixir suits mastering, broadcast, post-production, and immersive-audio engineers who need multichannel true-peak control and platform-oriented presets. Those seeking a standalone application or a wider collection of mastering processors should choose a different type of tool.
