Compression is such a big topic; and today I want to show you a really great technique to create your own multiband compressor for mastering applications.
So what is a multiband compressor and how do you create one?
Here’s the science part:
1. A single band compressor processes the entire frequency range of the audio signal.
2. A multi-band compressor separates the spectrum of the audio signal into several frequency bands, each of which can then be compressed individually.
Step 1. Take your original stereo mix and duplicate it onto 3 new audio tracks.
Step 2. Insert a compressor onto the 1st duplicated track.
Step 3. Copy that same compressor onto the other two duplicates.
Step 4. Bypass the compressors
Step 5. Now, on the first duplicate track, add a low pass filter at 100Hz.
Step 6. Name the track ‘low’
Step 7. On the last duplicate track, add a high pass filter at 10KHZ
Step 8. Name the track ‘high’
Step 9. On the second duplicate track, set up band pass filtering with low pass at 10KHz and High Pass at 100Hz
Step 10. Name the track ‘mid’
So, what I have done is create the low, mid and high range bands for the track.
When you play all three tracks together, they will sound identical to the original.
But, play each track separately and you will hear which frequencies will be processed by the individual compressors set up on each track.
You now have the power to control the dynamics of each frequency band independently! And shape the sound dynamically. This is really powerful as a dynamic EQ option.
If you want to learn more about compression have a look at the Quick Dial Series on Compression which you can find in our course offerings here
Give it a try, & have some fun!
I’ll catch you again next time!
