Sub-bass is the frequency range below human hearing, typically defined as 20Hz to 60Hz. It is responsible for the deep rumble and thump that is characteristic of many genres of music, including EDM, hip hop, and rock.
While sub-bass is often felt more than heard, it is an important part of the mix, as it can add depth and power to the music. However, too much sub-bass can make the mix sound muddy and boomy.
One way to avoid this is to cut certain frequencies from the sub-bass range. Here are some tips:
- Cut frequencies below 20Hz. These frequencies are inaudible to humans, but they can still consume headroom and make the mix sound muddy.
- Cut frequencies that clash with other instruments. For example, if your kick drum has a fundamental frequency of 40Hz, you may want to cut some frequencies around 40Hz from your sub-bass to avoid them clashing.
- Cut frequencies that are not contributing to the desired sound. For example, if you are going for a dark and ominous sound, you may want to cut some of the higher frequencies from your sub-bass.
You can use an equalizer to cut frequencies from the sub-bass range. Be careful not to cut too much, as this can make the sub-bass sound weak and lifeless.
Here are some additional tips for working with sub-bass:
- Use a high-pass filter to remove any low-end frequencies from your other instruments. This will give your sub-bass more room to breathe and make it sound more powerful.
- Use a compressor to control the dynamics of your sub-bass. This will help to keep it from overpowering the rest of the mix.
- Use an equalizer to adjust the frequency and level of your sub-bass. This will help you to achieve the desired sound.
- Be careful not to overuse sub-bass. Too much sub-bass can make your mix sound muddy and boomy.
By following these tips, you can use sub-bass to add depth, power, and excitement to your music without making it sound muddy or boomy.
