This week's featured free plug-in from our free plug-ins database is SpectrumAnalyzer from SIR Audio Tools. SpectrumAnalyzer is described as "a state-of-the-art spectrum analyser plugin", designed to offer a lot of opportunities to display the spectral content of your audio material and helps you create a better mix this way and comes in two editions, a free and a full version.

SpectrumAnalyzer has an FFT (Fast-Fourier-Transform) and an analog-style (parallel bandpass 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 analyser, 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.
