Blue Cat's FreqAnalyst Multi - Real Time Multi Tracks Spectrum Analyzer (AU, VST, AAX and VST3 Plug-in)

Blue Cat's FreqAnalyst Multi is a unique multiple tracks real time spectrum analyzer: 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.

FreqAnalyst Multi is the ideal solution for mixing: you can use it as a frequency overlap detector and actually see which part of the spectrum every single instrument uses. It is now also possible to easily compare the spectrum of several instances (for EQ matching or response curve measurement) thanks to the new 'Diff' view which displays the difference between several curves.

Just like with Blue Cat's FreqAnalyst Pro plug-in, 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 advanced routing capabilities you can define different settings for each track and thus adapt the analysis for each audio signal you want to analyze. Our multiple tracks tutorial shows you how simple multiple tracks spectrum analysis can be.

The four memory slots let you store any curve in memory: it helps you make comparisons between several setups or portions of your audio project very easily.

Thanks to included window opacity management feature and advanced layout customization capabilities, you can adapt the plug-in user interface to your personal needs and enhance your workflow. It is also possible to create a completely custom user interface using Blue Cat's skinning language.

If you are looking for a single track spectrum analyzer with a spectrogram view and audio to MIDI capabilities, check our Blue Cat's FreqAnalyst Pro plug-in.

User Comments & Reviews

"If you are serious about mixing, (and who isn't!), then this piece is a must have! - Glen Heffner, CakewalkNet

"You could use it in a mix, to find out which of your tracks are stepping on each other's frequencies, but the obvious application is for mastering, and I quickly found it very useful for comparing my own mixes with reference material. Four memories are available to capture curves, but it's the ability to see multiple analyses together in real time that really makes this an unusual plug-in." - Sound On Sound Magazine - May 2008
