Fruity Compressor is the stock compressor that ships with every edition of FL Studio. It is simple, fast and more capable than its plain interface suggests. This guide explains what each control does, then gives you starting settings for vocals, drums and bass so you can stop guessing and start mixing.
What a compressor actually does
A compressor turns down the loud parts of a signal so the level stays more consistent. Quiet parts stay where they are, loud parts get reduced, and you then raise the overall gain to make the whole thing feel denser and more controlled.
Before you compress anything, make sure your levels are healthy. Our guide to gain staging covers why a compressor reacts very differently to a signal that is too hot or too quiet.
Opening Fruity Compressor
- Select a mixer track (for example your vocal or kick).
- Click an empty effect slot on the right of the mixer.
- Choose Fruity Compressor from the list.
You will see a small window with a few knobs and a gain reduction meter. Everything you need is there.
The controls explained
| Control | What it does | Typical range |
|---|---|---|
| Threshold | The level above which compression begins | -15 to -30 dB |
| Ratio | How strongly the signal above the threshold is reduced | 2:1 to 6:1 |
| Gain | Makeup gain to restore level after compression | Set by ear |
| Attack | How quickly compression kicks in after the threshold is crossed | Fast: 1-10 ms, slow: 20-50 ms |
| Release | How quickly compression lets go | 50-300 ms |
| Type | Switches between a hard-knee and a softer character | Try both |
Threshold and ratio
Lower the threshold until the gain reduction meter shows the amount you want. Then choose the ratio: low ratios (2:1) are gentle and transparent, higher ratios (6:1 and up) clamp harder and start to sound obviously compressed.
Attack and release
A slower attack lets the initial punch of a drum or pluck through before the compressor grabs it. A faster attack softens transients. Release should ideally return to zero just before the next note or hit, so the compressor breathes with the groove instead of pumping against it.
Gain (makeup)
After compressing, the signal is quieter. Raise gain until the compressed sound matches the bypassed one in loudness. Compare fairly: louder almost always sounds better, so match levels before you decide.
Starter settings you can try
These are starting points, not rules. Every recording is different, so adjust the threshold first and trust your ears.
Vocals
- Ratio: 3:1 to 4:1
- Attack: medium (10-20 ms) to keep consonants clear
- Release: 100-200 ms
- Aim for 3-6 dB of gain reduction on the loudest phrases
Drums (kick and snare)
- Ratio: 4:1
- Attack: slower to preserve the punch
- Release: fast, so it recovers before the next hit
- Aim for 2-4 dB of gain reduction
Bass
- Ratio: 4:1 to 6:1
- Attack: medium
- Release: 100-250 ms
- Aim for steady level so the bass sits evenly under the mix
Common mistakes
- Over-compressing. If the meter is pinned and the sound feels flat, back the threshold off.
- Ignoring makeup gain. Compression that only makes things quieter is not helping.
- Setting and forgetting. Re-check compression after you change EQ or arrangement.
- Compressing before fixing the source. Bad recordings need better takes, not more compression.
A simple workflow
- Set ratio to 3:1 and attack and release to medium values.
- Lower the threshold until you see 3-4 dB of reduction on peaks.
- Adjust attack until the transients sound the way you want.
- Adjust release so the meter bounces back with the rhythm.
- Raise gain to match the original loudness and A/B against bypass.
When to reach for another plugin
Fruity Compressor is great for learning and for quick jobs. If you want more character, look at dedicated compressors; our collection of free VST plugins is a good place to find alternatives to try alongside it.
FAQ
Is Fruity Compressor good enough for a professional mix?
Yes for many jobs. The tool matters less than knowing why you are compressing and listening carefully.
Where do I put the compressor in the chain?
Commonly after corrective EQ and before creative effects like reverb, but it depends on the source.
How much gain reduction is right?
Usually 2-6 dB for most sources. Use more only when you want an obvious effect.
Should I use it on the master?
Very gentle compression (1-2 dB) can glue a mix, but it is optional and should never replace fixing the balance.
Key takeaways
Set the threshold first, choose a ratio that suits the sound, shape attack and release to the rhythm, then match loudness with makeup gain. Practise on one instrument at a time and compare with the plugin bypassed.
