How to Use Blue Cat’s FreqAnalyst Pro for Mixing Visual analysis tools are essential for creating professional mixes. Blue Cat’s FreqAnalyst Pro is a powerful, real-time spectrum analyzer that helps you see what you cannot hear. It reveals hidden frequency conflicts, uncontrolled low end, and tonal imbalances.
This guide covers how to set up and use FreqAnalyst Pro to improve your mixing workflow. 1. Setting Up the Analyzer
Proper placement of the plugin ensures you get accurate visual feedback.
Master Bus Placement: Insert the plugin at the very end of your master chain. Place it after your final limiter to analyze the exact output of your mix.
Channel Routing: Insert instances on individual problem tracks, like the kick drum and bass guitar.
Sidechain Configuration: Route a secondary track into the plugin’s sidechain input. This allows you to view two different signals simultaneously on a single graph. 2. Choosing the Right Display Modes
FreqAnalyst Pro offers multiple visualization modes to suit different mixing tasks. Spectrum View
The standard graph displays frequency on the horizontal axis and amplitude on the vertical axis. Use this to find specific frequency build-ups or resonant peaks in individual tracks. Spectrogram (Waterfall) View
This mode displays frequency activity over time using color intensity. It is highly effective for spotting intermittent background noise, harsh vocal sibilance, or muddy rings that linger too long. Left/Right and Mid/Side Modes
Switching to stereo analysis helps you manage your spatial image. Use Mid/Side mode to ensure your low frequencies stay mono in the center, and to verify that your high-end stereo widening does not create phase cancellation. 3. Optimizing the Graph Settings
Standard plugin presets rarely match the specific needs of a mix. Adjust these parameters for better accuracy.
FFT Size: Increase the FFT size (e.g., to 4096 or 8192 samples) for precise low-end analysis. Lower the FFT size for faster response times when mixing fast transients like drums.
Speed and Decay: Slow down the response times to view the average tonal balance of your song. Fast decay settings are better for catching sudden, short volume spikes.
Slope (Tilt): Set the graph tilt to 3 dB or 4.5 dB per octave. This compensates for the human ear’s natural sensitivity and makes a balanced mix look flat on the screen. 4. Solving Common Mix Problems
Visual analysis speeds up troubleshooting in crowded arrangements. Uncovering Low-End Mud
Insert the plugin on your master bus and solo the kick and bass together. Look for a massive energy peak between 20 Hz and 60 Hz. If the graph shows a bloated curve, apply a high-pass filter to clean up unnecessary sub-bass frequencies. Fixing Frequency Masking
Use the dual-curve or sidechain view to compare competing instruments, such as vocals and electric guitars. Look for the areas where the two curves overlap heavily. Apply a subtle EQ cut on the guitar track at the exact frequency where the vocal needs to cut through. Matching a Reference Track
Load a professionally mixed commercial song into your session. Route it through FreqAnalyst Pro and save its average frequency curve. Overlay your own mix curve on top of it to immediately see if your track needs more brightness, warmth, or midrange presence. 5. Utilizing Automation and MIDI Outputs
A unique feature of FreqAnalyst Pro is its ability to transform audio curves into control data.
Envelope Generation: The plugin can extract the volume envelope of a frequency band and turn it into MIDI CC data.
Dynamic EQing: Route this generated MIDI data to control an EQ plugin on another track. For example, every time the kick drum hits, the plugin can automatically pull down the matching frequency on the bass guitar. To help tailor this guide to your specific setup, tell me: What genre of music are you currently mixing? Which DAW (Digital Audio Workstation) do you use?
Are you having trouble with a specific instrument conflict (like kick and bass)?
