Simple Question. I was watching a video and I can't seem to find it anymore on how to calculate Quaternary Frequency Colors. Can someone break down the rules to calculating them? My best guess is: • Adding any two primary frequencies. • Adding a primary frequency to a secondary frequency. • Adding a primary frequency to a tertiary frequency. Am I missing any other combination or are my assumptions wrong?

Hi Everyone I'm a music producer who's uses COS Pro alot, and I must say, it's significantly improved the quality of my music. However, I've encountered a recurring issue related to dynamic range, especially while working on mixing tracks with dynamic elements like pianos and bass. Here’s my process: 1. I start by checking the Peak to Loudness Ratio (PLR) and peak of the sound using a LUFs Loudness Meter. 2. My first step is to EQ using COS at 100% to fine-tune the tone. 3. Then, I apply COS again at 50% to find an average, generate a ceiling, then make minor adjustments to follow the noise guides like 4.5, 6, etc. I adhere to the ceilings at 50% 4. I then switch to 0% based on the 50% ceilings and fine tune the sound at 0% because I've come to like the tone and tightness of 0% on most sounds. 5. Next, I compress the sound to the desired PLR, for example, reducing a bass from 18 PLR to 12. 6. I open another instance of COS, using the same ceilings from the 50% setting but reverting the view back to 0%. 7. I line up 20 hertz to the bottom of the sound and I make my adjustments to parts that exceed the ceiling. My COS will typically have a “wave” pattern after I have done the adjustments to restore the sound post-compression. However, I've noticed a problem, particularly with bass tracks. Even minor EQ adjustments post-compression tend to reduce my compression, increasing the dynamic range by 1-2 dB. While other sounds seem more resilient, maintaining their PLR, I'm wondering if I'm handling the post-EQ incorrectly. The only workaround I’ve found is using a limiter on the track to bring the dynamic range back to the desired level, but I understand this can alter the equalization, similar to a compressor. Any insights or advice on managing this issue would be greatly appreciated!
