The Reflex Spectrum Analyzer includes the standard features you'd expect from this category of plugin—such as stereo comparison and the ability to tilt and smooth the display.
Where this plugin stands out is its ability to show responsive and granular bass information. Technically speaking, the device uses four 512-element FFT analyses in a multiband configuration with distinct sample rates, chosen to optimize the distribution of the resulting 1,024 frequency bins across the audible range. The design achieves low-end bin spacing of just 0.7Hz, equivalent to that of a single 65,536-element FFT.
The combined frequency amplitude spectrum is displayed in a streamlined fashion on a semitone log scale covering 11 octaves from 10Hz to 20kHz. While the laws of information theory prevent us from viewing low-frequency information at high resolution in both the time and frequency domains simultaneously, Reflex brings you closer to what's possible.
