RX 6 Spectral De-noise
RX 6 Spectral De-noise is an Audio Unit (AU) plugin from iZotope that removes background noise, hum and unwanted audio artifacts from recordings. It is used by podcast producers, audio engineers, voice-over artists and music producers to clean up dialogue, acoustic recordings and field audio before mixing or mastering. The plugin integrates into Digital Audio Workstations and audio editing software that support AU plugin standards on macOS.
AI Recommendation
1 suggestionRX 6 Spectral De-noise is a plugin component, not a standalone application — it runs inside a host DAW or audio editor and is updated through iZotope's own update tools, not separately. iZotope released native Apple Silicon versions of RX plugins starting with RX 9 (released in 2021), but RX 6 is an older generation and does not have a native build. The Intel-only RX 6 plugin currently runs under Rosetta 2 but will stop working when Apple removes Rosetta in macOS 28 (September 2028). To future-proof your workflow, upgrade to RX 9 or later via the iZotope Product Portal — the current builds include native Apple Silicon support and run natively on M-series Macs with no performance hit. If you need to stay on RX 6 for compatibility reasons, contact iZotope Support to confirm whether a native build is planned before September 2028, since the Intel version will not launch on that macOS release.
