Plugins and effects shape a sound after it exists, whether that sound was just recorded or just programmed. EQ carves frequencies out or pushes them forward. Compression evens out a performance that’s too dynamic to sit in a mix. Reverb and delay add space that was never physically there.
It’s for anyone shaping tone and character past the initial recording or programming stage, mixing engineers balancing a full session, and producers using processing as a creative tool rather than just a corrective one.
Some of the effects producers now reach for as plugins started as physical accidents nobody could easily repeat. When Led Zeppelin recorded “When the Levee Breaks,” engineer Andy Johns set John Bonham’s drum kit up at the bottom of a stairwell at Headley Grange and mic’d it from several floors up, capturing the natural reverb of the space itself rather than adding anything artificial. The resulting drum sound became one of the most sampled breaks in hip-hop history, chased by engineers for decades afterward. Modern reverb plugins that model specific rooms and halls exist largely because almost nobody has a usable stairwell on hand.
Browse this category if a sound is technically finished but doesn’t yet have the character, space, or polish the material actually calls for.

What to look for in a Plugins & Effects
- Corrective or creative
- Some processing fixes a problem, an uneven level, a harsh frequency. Other processing exists purely to add character that wasn't there to begin with. Knowing which job you're doing changes how aggressively you should use it.
- CPU cost at scale
- One instance of a demanding plugin is nothing. Twenty instances across a full mix can bring a session to a crawl. Check how a plugin performs under real project load, not just in isolation.
- Format compatibility
- VST3, AU, and AAX aren't universal. A plugin that works perfectly in one DAW may not exist in a format your specific setup can even load.
- Whether it's trying to sound like something real
- A lot of processing emulates physical hardware, tape, tube amps, real rooms. How convincing that emulation is, and whether it matters for your material, varies a lot between tools claiming to do the same thing.
Frequently asked questions
- Do I need expensive plugins to get a professional sound?
- Not necessarily. A lot of processing decisions come down to how well you understand what a tool is doing to the sound, not how much the tool cost. Free and stock plugins handle plenty of professional work.
- What's the difference between an effect and a virtual instrument?
- An effect processes an existing sound, changing what's already there. A virtual instrument generates sound from nothing, a synth or sampled piano triggered by a MIDI note. Plugins can be either.
- Why do so many reverb plugins model real rooms and halls?
- Because some of the most famous sounds in recorded music came from a specific physical space. Led Zeppelin's "When the Levee Breaks" drums were recorded through room ambience in a stairwell at Headley Grange, and that sound has been chased, and sampled, by producers ever since. Digital reverb exists partly to make spaces like that reachable without finding your own stairwell.
- Should I use plugins during recording or only afterward?
- Both happen in practice. Some effects are printed during recording as part of the performance, others are added entirely afterward during mixing, where they're easier to undo or adjust if something isn't working.
