OptoRed
OptoRed is an Audio Units (AU) plugin from ToneEmpire, a vintage optical compressor effect designed for use in Digital Audio Workstations and audio production software. It emulates the characteristics of classic optical compression used in professional studios, providing smooth, transparent compression suitable for mastering, mixing and tracking across vocals, instruments and full mixes. Like all ToneEmpire plugins, OptoRed integrates with any AU-compatible host application on macOS.
AI Recommendation
1 suggestionOptoRed is an audio plugin (AU format), not a standalone app, so it is updated through your DAW or plugin host, not directly from ToneEmpire's download page. To check whether a native Apple Silicon build exists, visit ToneEmpire's website and download or re-install the plugin using their official installer — do not rely on your DAW's built-in plugin browser to fetch it. If ToneEmpire has released a native version, the installer will place the native build on your system. Once installed, your DAW will automatically detect and use the native AU. If ToneEmpire has not yet shipped a native build of OptoRed, the current Intel-only version will continue to work under Rosetta 2 until Apple removes Rosetta in macOS 28 (late 2027), at which point the plugin will stop loading. Check ToneEmpire's release notes or contact their support to confirm whether a native Apple Silicon build is planned before that deadline.
