How To Use Compressor In FL Studio: A Complete Guide

When it comes to mixing music, compression is one of the most powerful tools you’ll ever use. If your track feels uneven, vocals sound too loud at one point and too quiet at another, or drums lack punch, then a compressor can fix it.

FL Studio comes with built-in compressor plugins, such as Fruity Compressor and Fruity Limiter, which are suitable for both beginners and advanced producers. In this guide, you’ll learn step by step how to use a compressor in FL Studio for vocals, drums, and instruments.

What is a Compressor in FL Studio?

A compressor is an audio effect that controls the dynamic range of a sound. In simple words, it reduces the difference between the loudest and quietest parts of your track.

• Without compression → vocals jump all over the place.

• With compression → everything sounds smoother, balanced, and professional.

Producers use compressors in FL Studio to:

• Make vocals clear and consistent

• Add punch to drums

• Balance instruments in the mix

How To Add a Compressor in FL Studio

Adding a compressor in FL Studio is super easy. Here’s how:

1. Open the Mixer (press F9).

2. Select the channel you want to compress (vocals, kick, snare, etc.).

3. In the Effects Slot, click on an empty slot.

4. Choose Fruity Compressor or Fruity Limiter.

That’s it—you’ve added a compressor to your channel.

Key Compressor Settings Explained

Before you start turning knobs randomly, you need to understand what each setting does:

• Threshold – Sets the level at which compression starts. (Lower threshold = more compression.)

• Ratio – Determines how much the sound is reduced once it crosses the threshold. (e.g., 4:1 ratio = strong compression.)

• Attack – How quickly the compressor reacts when sound goes above the threshold.

• Release – How quickly the compressor stops working after the sound goes back below threshold.

• Gain/Makeup – Boosts the compressed signal back to normal loudness.

Think of it like this: Threshold decides when to compress, Ratio decides how much, and Attack/Release decides how fast.

How To Use a Compressor on Vocals in FL Studio

Vocals are often the most important part of a song, so they need clear and consistent volume.

Step-by-step vocal compression in FL Studio:

1. Insert Fruity Compressor on your vocal track.

2. Set Threshold around -20 dB (adjust depending on recording).

3. Use a Ratio between 3:1 and 4:1 for natural vocals.

4. Set Attack between 5–10 ms to keep transients.

5. Use a Release of around 50–100 ms for smoothness.

6. Adjust Gain until vocals sit nicely in the mix.

Tip: Always listen carefully—if vocals sound too squashed, reduce the ratio or raise the threshold.

How To Use a Compressor on Drums in FL Studio

Drums need punch, and compression can make them hit harder.

Kick Drum Compression:

• Threshold: -15 dB

• Ratio: 4:1

• Attack: 10 ms

• Release: 100 ms

Snare Compression:

• Threshold: -18 dB

• Ratio: 5:1

• Attack: 5 ms

• Release: 120 ms

For extra punch, try parallel compression: duplicate your drum channel, add heavy compression on one, and blend it with the original.

Using Fruity Limiter as a Compressor

Not everyone realizes this, but the Fruity Limiter in FL Studio can also act as a compressor.

Here’s how:

1. Add Fruity Limiter to your track.

2. Switch to COMP mode.

3. Adjust Threshold, Ratio, Attack, and Release just like a normal compressor.

Many producers prefer Fruity Limiter because it shows a visual waveform, making it easier to see how compression affects your audio.

Common Compression Mistakes to Avoid

Even experienced producers make mistakes with compression. Avoid these:

• Over-compressing → Makes sound lifeless and flat.

• Too fast attack → Kills the natural punch of vocals/drums.

• Not adjusting gain → Track sounds quieter after compression.

• Compressing everything → Not every sound needs compression.

Best Practices for Compression in FL Studio

• Use your ears first, not just the visuals.

• Always compare with and without compression (A/B testing).

• Save your favorite presets for faster workflow.

• Combine light compression on multiple channels instead of heavy compression on one.

Conclusion

Learning how to use a compressor in FL Studio might feel tricky at first, but once you understand Threshold, Ratio, Attack, and Release, it becomes second nature. Whether you’re mixing vocals, drums, or instruments, compression helps balance your mix and make it sound professional.

Don’t be afraid to experiment—every track is different, and the best settings always depend on the music you’re creating.
