Seven Phase Spectrum Analyzer Port: Free Mac ARM Utility
Deeplab Music has released an Apple Silicon port of the classic Seven Phases Spectrum Analyzer, offering a free spectrum analyzer Mac ARM utility for modern DAWs. Rebuilt from the ground up using the original open-source codebase, the plugin delivers native ARM64 execution across modern macOS setups without Rosetta 2 emulation. You can grab the release directly from Deeplab Music on GitHub.
Filter-Bank Analysis for Modern Macs
Unlike standard FFT-based metering tools that introduce latency and FFT windowing artifacts, Seven Phase Spectrum Analyzer utilizes a fractional-octave filter bank architecture. This design closely resembles vintage analog hardware spectrum analyzers, offering smooth ballistic decay curves and musical separation across critical low frequencies.
Key features include:
- Filter-bank processing based on fractional-octave frequency bands
- Native Apple Silicon ARM64 performance with near-zero CPU usage
- Configurable peak hold, attack, and release ballistics
- Stereo, mid, side, and combined monitoring configurations
- Resizable vector user interface scaled for Retina displays
Formats and Licensing
The ported Seven Phase Spectrum Analyzer is distributed in 64-bit VST3 and Audio Unit (AU) formats for macOS 11 Big Sur and newer. Because the original source code is governed by the permissive MIT license, the ported software is 100% royalty-free for both personal production and commercial mixing workflows.
The Seven Phase Spectrum Analyzer Mac ARM port is available as an open-source download without copy protection or registration requirements. It provides macOS engineers with a responsive, hardware-style spectral display tailored specifically for modern Apple Silicon processors.

FAQ
Is Seven Phase Spectrum Analyzer really free?
The plugin is completely free and open source under the MIT license, requiring no registration, dongles, or activation codes.
What DAWs does the Mac port support?
It works in any macOS host that supports 64-bit VST3 or Audio Unit plugins natively on Apple Silicon, including Logic Pro, Ableton Live, Reaper, and Studio One.
How does a filter-bank analyzer differ from an FFT analyzer?
Filter-bank analyzers use dedicated bandpass filters to mimic physical analog meters, resulting in musical frequency spacing and natural ballistic decay without FFT block delays.
