The record

Purpose: SpectrumAnalyzer is an audio spectrum analyzer plugin for viewing spectral content and assessing a mix’s frequency balance.
Analyzer engines: It includes FFT and analog style parallel band-pass IIR filter engines, which can be used at the same time.
Mid/side analysis: The plugin can display the spectral content of the mid/side signal in a separate analyzer slot.
Auxiliary audio: Its auxiliary feature can send audio between SpectrumAnalyzer instances, subject to the DAW using the same process and memory space for those instances.
Display and analysis: Features include multiple analyzer slots, snapshots, freeze, peak detection, RMS display for the analog band analyzer, a VU meter and stereo correlation meter.
Plugin formats: The product page lists VST, VST3, AU and AAX formats.
Host requirement: SpectrumAnalyzer is a plugin rather than a standalone program and must be used with a DAW; the maker names Logic, Ableton Live, Cubase and Pro Tools as examples.
Operating systems: Downloads are offered for Windows and Mac; the listed requirements are Windows 11 or newer and Mac OS 10.13 or newer.
System requirements: The maker lists 200 MB disk space and 8 GB RAM for both Mac and Windows.
License use: A license owner may install the product on multiple devices belonging to them for their own use; simultaneous use by multiple users is expected to require additional license keys.
Apple Silicon: The support page says SpectrumAnalyzer runs natively on Apple Silicon M-series devices.
Support: The maker provides product manuals, downloads, license key recovery and email support at [email protected].
Privacy and checkout: The maker says purchases are processed by Cleverbridge AG and that checkout data is governed by Cleverbridge’s privacy policy.
Privacy controls: The privacy policy says analytics and advertising cookies are set only after consent, and describes GDPR rights including access, correction, deletion and portability.
