Blue Cat's FreqAnalyst Multi is a multi-track spectrum analysis plugin. Using Blue Cat Audio's exclusive data sharing technology, it lets you visualize the spectral content of several audio tracks on the same screen with extreme smoothness and high resolution for both time and frequency. You can actually see which part of the spectrum every single instrument uses while doing your mix.
Just like with Blue Cat's FreqAnalyst Pro, the frequency analysis can be fine tuned in details, and three modes are offered for each channel: instant, peak or average response of several audio tracks can be displayed on the same graph (the plugin supports up to 16 curves). Zooming capabilities and coordinates display let you exactly measure the characteristics of the spectrum for each audio track. Thanks to the routing capabilities you can define different settings for each track and thus adapt the analysis for each audio signal you want to analyze. A tutorial shows you how to use this plugin for multiple tracks spectrum analysis.
