Schulz Audio ‘Spectrum 2’: A Multichannel Spectrum Analyzer ideal for handling Clashing Frequencies in your Mix

 

The Easiest and Fastest way ever to keep your track clean and vivid from dulness of overlapping frequency collisions 

 

 

 

 

 

Schulz Audio's 'Spectrum 2' is a multi-channel spectrum analyzer plug-in that allows you to inspect the frequency content of your mixes. It is ideal to find clashing frequencies and clean up your mix. 

 

Spectrum 2 analyzes multiple tracks in real-time providing users with a variety of data such as frequency contents, dB levels, musical notes of the signal, and peak information, so you can easily notice any problem of clashing frequencies between different tracks. 

 

Spectrum 2 adopted the multichannel technology of 'Oszillos Mega Scope', a Schulz Audio’s another acclaimed ‘Beat-Synced Multi-Channel VST Oscilloscope’ plug-in, so Spectrum 2 supports input from multiple channels. This technology, so called ‘Zero Routing’, allows you to drop an instance at each point in your signal chain where you want to measure the frequency contents. So you can simply insert Spectrum 2 anywhere on the signal chain without routing and the instances will find each other. This is super-fast way to set up the instances. 

 

Spectrum 2 also features a low CPU consumption since it covers all the channels simultaneously by inserting it into your master channel. So it is not necessary to use one analyzer per channel. 

 

Spectrum 2 is available as VST, AudioUnits, and AAX for macOS and Windows system. 

 

 

 

 

 

Main Structure and Functions  

Spectrum 2 is a very useful tool especially when you need to constantly sort or check between different sounds and you are struggling with a mix element having conflicts with one another in its frequency range. Spectrum 2 is super easy to use and allows you to deep dive into how the different sounds in your tracks are interacting together. Definitely, Spectrum 2 is a must-have multi-channel spectrum analyzer plug-in which aims to facilitate your mixing works. Let’s take a look at the major features of the interface to quickly catch up the use of Spectrum 2

 

 

 

▲ Settings panel (1)


The controls in ‘Settings’ panel are used to define all the settings and UI (User Interface) elements of Spectrum 2. ‘Block Size’ allows users to select FFT size. This FFT size defines the frequency resolution of the window. If the knob turns into the very left, then 2048 samples are used. Contrary, if the knob turns into the very right, then 16,384 samples are used. Less samples give a faster response, but more samples render a better frequency resolution. ‘Refresh’ defines how often to compute a new spectrum in the window. ‘Average’ is used to decide how many FFT frames to average before they are displayed on the window. If you want to know the overall frequency shape of your mix, set this to a high value. If you need higher resolution, set this to a lower value. ‘Max dB / Min dB’ defines the dynamic range of the signal to be shown in the window. Once you touch one of those knobs, the range will switch to manual mode. If the range switch is set to auto, those knobs will display the auto-selected values. 

 

 

 

▲ Settings panel (2)


‘Graph (Fill/Line)’ decides whether the graph to be filled or just the outline to be displayed on the window. ‘Range (Manual/Auto)’ defines whether the dynamic range of the signal to be displayed is manually set or automatically generated. ‘Channels’ provides Stereo and M/S options. If you want to display both the left and right input channels then select Stereo. If you want the left and right input channels to be converted into Mid/Side mode then select M/S before any other processing is performed. The Mid channel is basically the sum of the left and right channel and the Side channel is the difference of the left and right channel. If your input is mono, the side channel will be silent, and contrary if the input is a very wide stereo signal then the side channel will be very prominent. ‘Spectro (Graph/Gram)’ decides whether you display Spectrograph or Spectrogram of the input audio. 

 

 

 

▲ Spectrograph mode

 

▲ Spectrogram mode


When Spectrum 2 is running under spectrogram mode, setting lower dynamic range is better because only the changing part of the spectrum is tightly displayed. The resulting spectrogram is much easier to read and have better contrast since the colors of the different input channels make discernible when analyzing the frequencies.
