Spectrum is a VST, AU and AAX multi channel spectrum analyzer plugin that allows you to inspect the frequency content of your mixes. It's ideal to find clashing frequencies and to cleanup your mix. It supports input from multiple channels: just drop an instance at each point in your signal chain you want to measure.

Coming from the creators of Oszillos Mega Scope, one of the best oscilloscope plugins on the market, Spectrum is a very promising release.

Definitely a good idea for an analyzer.

The interesting thing about this plugin is that you can analyze several tracks of your track with a single effect, since you only have to insert it into the master channel to see how different instruments are working. This way it is easy to realize if there is any problem of frequency collision between your different tracks. All this you can do in a simple way thanks to its color graphics that inform you about the frequency, the level in dB and the musical note of each channel. You can even switch to the mid / side function, if you want to create a mix type this way. A good detail is that this helps you to keep a low CPU consumption, since it is not necessary to use one analyzer per channel.

Zero Routing

Starting with version 1.0.50 no routing is required. Just create an instance of Spectrum anywhere in your signal chain where you want to measure. This not only makes routing less cumbersome, it also adds support for DAWs that have limited routing capabilities. And more importantly, you can now create an instance of Spectrum before and one after your EQs or other processors to visualize the effect.
