REAPER Multiband Compressor (In-Depth Guide)

REAPER has a multiband compression plugin called ‘ReaXcomp.’ You can use this multiband compressor to compress different frequency ranges at different levels and amounts. To use ReaXcomp, click the ‘Show Track FX Window’ button on the desired track, search for ReaXcomp, and double click to insert it onto your track.

Does REAPER Have A Multiband Compressor?

Sometimes using a standard compression plugin does not give you enough control over the entire frequency range of certain parts of your mix.

In these cases, I count my lucky stars that REAPER has a multiband compressor called ‘ReaXcomp.’

What Is The Function Of A Multiband Compressor?

The function of a multiband compressor is to compress different parts of a track’s frequency range at different amounts.

Multiband compressors are a beneficial tool to compress only a specific part of a track’s frequency range and leave the rest untouched.

How Does a Multiband Compressor Work?

A multiband compressor works by applying compression only to the parts of a track’s frequency range that you want to compress.

You can do this by setting your number of frequency bands, the desired frequency range of each band, and the compression settings of each band, such as thresholdratiokneeattackrelease, etc. 

Should I Use Multiband Compression?

You should not use multiband compression in every instance. 

Here are some situations where I like to use multiband compression:

  • Having more dynamic control over your vocals than a regular compressor can offer
  • Controlling kick drum and bass guitar
  • Adding life to your entire mix or master track

Remember that you can use multiband compression in any instance you feel will benefit your mix; you can even get creative with it. This list is just a few common uses of a multiband compressor.

Does REAPER Have a Compressor?

Yes, REAPER has several compressor plugins under the Cockos and JS plugin collections that come with REAPER. 

If you are looking for a regular compression plugin, I recommend using ReaComp

How Do You Use Compression In REAPER?

To use compression in REAPER, click the ‘Show Track FX Window‘ button on the desired track, find the compression plugin you want to use (I recommend ReaComp), and either select a preset from the preset menu or tweak your own settings.

Keep in mind that there are several other compression plugins in REAPER. 

I recommend ReaComp because it is simple and has a few presets, which can be helpful for music production beginners.

How Do You Use A Multiband Compressor On Guitar?

To use a multiband compressor to clean up muddiness on a guitar, start by loading up your desired multiband plugin on your desired guitar track. 

Set up a frequency band in the lows and low mids. 

I recommend using a low shelf up to around 250-300 Hz

This will make it so your multiband compressor compresses only this low-frequency range. 

Using Multiband Compression On Guitar

Remember that attack and release play a significant role in multiband compression. 

Tweak these settings until the track sounds compressed but also natural.

You can use this multiband compression technique to clean up the low-frequency range on your guitars.

How Do You Use A Multiband Compressor For Vocals?

To use a multiband compressor to clean up low mids on a vocal track, start by loading up your desired multiband compressor on your vocal track.

Next, set up a frequency band between 250-500 Hz, depending on where the issues are in your track. 

Once you have located the issues in your vocal track and applied multiband compression to this area, you will notice that your vocal track sounds much cleaner now.

Take your time setting the attack and release on your compressor. 

Attack and release play a significant role in using multiband compression.

How To Use A Multiband Compressor For Mastering

To breathe new life and energy into your track, you can use multiband compression on your master fader/master track. 

To do this, insert a multiband compressor onto your master track and set up a band in the mids and higher mids. These are the two frequency ranges that we want to control. 

Depending on your track, I recommend setting it somewhere between 250-1,000 Hz for the first band.

I recommend setting the second band between 5,000-10,000 Hz.

Keep in mind that we are working on the master fader now, so we want to be very light-handed with this technique. 

We only want to compress each of these frequency ranges a bit.

What Parts of Your Mix Do You Use Multiband Compression On?

Are REAPER stock plugins good?

Yes, REAPER stock plugins are pretty good. If you are a music producer who knows what they are doing, you can use REAPER stock plugins to achieve professional results.

Does EQ Come Before Compression?

For the most part, yes. EQ is almost always the first or maybe second plugin on my FX chain when I am mixing or mastering with compression following right after.

Typically this is my order of EQ and compression; subtractive/clean up EQ using dynamic EQ>compression>additive EQ using dynamic EQ.

Keep in mind that there are no right or wrong answers in music production, but it is wise to stick to the guidelines laid out for us by the professionals.
