Ghost Note Audio has released Spectrum Thief, a free EQ-matching plugin designed for precise frequency analysis and tone-matching tasks. The plugin is available in VST format for Windows and macOS, and as an Audio Unit for macOS. No registration or activation is required.
Spectrum Thief excels at capturing and matching the frequency response of any audio signal. It can be used to analyze and replicate the tonal characteristics of speaker cabinets, guitar tones, or even entire mixes by comparing them to a reference track.
EQ Matching with Impulse Response Export
The plugin not only matches EQ curves, but also allows users to export impulse responses. This makes it a useful tool for sound designers, mix engineers, and guitarists looking to apply consistent tonal shaping across different tracks or sessions.
By sampling a reference and target signal, Spectrum Thief creates an accurate EQ adjustment curve, helping users achieve the desired tonal match quickly and transparently.

Spectrum Thief is lightweight, easy to use, and completely free. There’s no account signup or license activation, just download and start using it immediately.
