Reflex Acoustics Spectrum Analyzer v1.0.6 VST3 AU AAX WiN MAC

Reflex Acoustics Spectrum Analyzer is a free VST3, AU, and AAX plugin for Windows and macOS that focuses on delivering detailed low-end frequency information. Unlike conventional analyzers that use a single FFT window, it runs multiple FFT analyses with different sample rates and window sizes, ranging from about 12 ms in the highs to 340 ms in the lows. The result is a clear, semitone-spaced display covering 11 octaves from 10 Hz to 20 kHz, with 132 bands and a 90 dB range. You can adjust smoothing across frequency and time, switch between Left-Right and Mid-Side stereo modes, and view short-term LUFS. Other features include spectrum tilt options, peak frequency display on a chromatic scale, adjustable GUI size, and an optional dark mode. You can also audition specific frequencies by clicking or dragging on the display, and compare two signals via sidechain input. This tool is ideal for hobby producers working in FL Studio, Ableton, or Logic who want better insight into bass and sub-bass content when mixing or mastering.
