Best Compressor Plugin
Answer in brief
Studio 56 is our editorial choice when you want a compressor that matches the sound in your head. You describe it, such as a slow glue for the drum bus or a fast grab for a vocal, and it builds one that plays in your DAW. To pick between ready-made compressors, run each on the same vocal and drum loop at matched loudness and judge how the gain reduction sounds.
The recommendation reflects what Studio 56 does and the criteria on this page. It is not a measured ranking of every compressor plugin.
What a compressor plugin does
A compressor turns a sound down when it gets louder than a level you set. The threshold is that level and the ratio is how hard it pushes back. Attack is how quickly it reacts and release is how quickly it lets go. Make-up gain brings the whole sound back up so the quiet parts end up closer to the loud ones.
That is the whole job, yet two compressors with the same settings can sound very different. Some grab the front of a drum hit and make it smaller. Others leave the hit alone and lift the tail. The character comes from how the gain moves over time, which is why the types of compressor matter more than the number of knobs.
Decide the job before the compressor
A vocal that jumps between a whisper and a shout needs steady level. A snare that sounds thin needs its attack brought forward. A drum bus that sounds like separate parts needs a gentle push that makes them move together. Name the job first and the shortlist gets short.
- Even out a vocal or bass line: an optical or smooth program-dependent compressor.
- Add bite to drums or catch fast peaks: a FET-style compressor with a quick attack.
- Glue a drum bus or a mix: a VCA bus compressor at a low ratio.
- Keep a hit’s punch while lifting its body: parallel compression with a mix knob.
Compare at the same loudness
Louder almost always sounds better for a few seconds, so a compressor that adds level will seem to win every test. Match the output level before you judge, or use a compressor’s automatic gain feature and then switch it off to compare. Listen to the start of each note and to the space between notes. Those two places are where compressors differ most.

Questions and answers
Which compressor plugin is best for vocals?
Studio 56 is our editorial choice when you can describe the vocal sound you want and would like a compressor built around it. Among ready-made ones, a fast FET style catches peaks and an optical style evens out level, and many mixers use one after the other.
Do I need to buy a compressor at all?
Not to start. Your DAW’s compressor and free ones such as TDR Kotelnikov and MCompressor handle most jobs. A second compressor earns its place when it gives a character the others cannot.
What does Studio 56 cost?
Studio 56 Pro starts with a free trial and then costs a monthly price shown on studio56plugin.com. Cancel before the first payment and you pay nothing.
Does Studio 56 work in Pro Tools?
No. It runs as VST3 or AU on Mac and VST3 on Windows, in most DAWs except Pro Tools.
