SpectrumAnalyzer is a spectrum analyzer plugin that offers a lot of opportunities to display the spectral content of your audio material, which helps you create a better mix. SpectrumAnalyzer comes in two editions, a free and a full version.

SpectrumAnalyzer has a FFT (Fast-Fourier-Transform) and an analog-style (parallel band-pass IIR filter) engine, both of which can run simultaneously. So you can benefit from the more accurate time resolution of the band-pass filters and the better frequency resolution of the FFT at the same time. Check out the intelligent peak-detection, which automatically detects resonant frequency peaks in the signal. Use the snapshot function to easily save the current state of your analyzer, so you can compare the spectral profile of your current project with other songs. SpectrumAnalyzer also includes a VU-Meter (with peak and RMS measurement) and a Stereo Correlation Meter.

SpectrumAnalyzer features an auxiliary feature that makes it possible to send audio from one SpectrumAnalyzer instance into other instances. This is a quite powerful tool, because you can set up as much aux-sends as you want, and then you can easily switch between them as input source. For example, you have different subgroups and want to see the spectrum of all of them in one SpectrumAnalyzer instance: put a single SpectrumAnalyzer instance on every track and activate the aux-send. Now you can comfortably switch between these aux-channels in your master SpectrumAnalyzer instance. In the full version, you can open up to 4 slots in one plugin instance.

SpectrumAnalyzer has nearly endless adjustment possibilities. To name a few: FFT-Size & Window. Number of Bands/Filter-Steepness and Bandwidth (analog style bandpass analyzer). Time Resolution & Release speed. Optional Peak Hold and intelligent Peak Detection. Spectral RMS with adjustable integration. Mid and Side Signal detection. Adjustable Colors, two different spectral smoothing algorithms. Display Range and Slope/dB. Adjustable GUI size and scaling. Optional gradient and shadow effects.
