Introduction
Your DAW ships with plugins. These are software tools that process audio: EQ adjusts frequency balance, compression controls dynamics, reverb adds space, delay creates echoes.
This lesson covers plugin categories and what they do, why the order you load them matters, CPU management as sessions grow, stock versus third-party plugins, and why presets are useful learning tools but rarely final solutions.
Frequently-Used Plugins
Everyone has their favorite and most often-used plugins that they accumulate over the years. Watch the video below to learn about some of our favorites and also for a quick discussion on:
Do you need additional plugins?

What is Gear Acquisition Syndrome and why should you care?
How can limitations be good for creativity?
1. What Plugins Actually Do
Plugins process audio or generate sound. Processing plugins (like EQ and compression) take incoming audio and modify it. Instrument plugins (like synthesizers and samplers) generate audio when triggered by MIDI.
-
You load plugins onto tracks, busses, or the master channel. Audio flows through plugins in the order they're loaded—top to bottom in most DAWs (left to right in Ableton Live). Each plugin in the chain receives the output of the previous plugin, processes it, and passes it to the next.
This serial processing means order matters. An EQ before a compressor produces different results than a compressor before an EQ. A reverb at the beginning of the chain sounds completely different than reverb at the end. The signal flow determines the final sound.
-
Processing plugins work on existing audio. You record a vocal, load an EQ plugin, and shape the frequency balance. The vocal is the source, the EQ is the tool. Without source audio, processing plugins do nothing.
Instrument plugins generate audio when they receive MIDI input. A synthesizer plugin creates sound when triggered by MIDI notes. No audio input required, the plugin is the source.
This distinction affects workflow. Processing plugins go on audio tracks that already have content. Instrument plugins go on MIDI tracks that contain note data.
2. Plugin Categories: What Each Type Does
Understanding Functional Categories
Plugins fall into functional categories based on what aspect of sound they affect. Each category serves a distinct purpose in shaping your mix, from controlling volume dynamics to sculpting frequency content, adding spatial depth, creating movement, or altering tonal character.
Dynamics Processors
Compressors, limiters, expanders, and gates control amplitude over time.
What They Do
Compressors reduce dynamic range by typically lowering loud peaks. Limiters prevent signal from exceeding a ceiling. Gates silence signal below a threshold.
What They Shape
These tools shape how loud or quiet elements are, how much variation exists between the loudest and quietest parts, and whether low-level noise gets through or gets silenced.
Frequency Processors
EQs and filters adjust frequency balance.
What They Do
An EQ lets you boost or cut specific frequency ranges. A high-pass filter removes low frequencies. In other words, it allows only frequencies above a certain cutoff point to pass. Hence the name high-pass. A low-pass filter removes high frequencies.
What They Shape
These tools shape tonal character: making something brighter or darker, removing muddiness, creating space between competing elements, emphasizing or de-emphasizing specific frequency ranges.
Time-Based Effects
Reverb and delay create spatial and temporal effects.
What They Do
Reverb simulates acoustic space by generating diffuse reflections. Delay creates distinct echoes by repeating the signal at specific intervals.
What They Shape
These tools add depth, dimension, and placement cues that help elements feel like they exist in space rather than sitting flat on a two-dimensional plane.
Modulation Effects
Chorus, flanger, phaser, and tremolo create movement through periodic variation.
What They Do
Chorus thickens sound by creating slightly detuned copies. Flangers create sweeping tonal shifts. Phasers create similar sweeps through phase cancellation. Tremolo creates rhythmic volume changes.
What They Shape
These tools add motion and texture, making static sounds feel more dynamic or evolving.
Distortion and Saturation
Add harmonic content through various forms of nonlinear processing.
What They Do
Light saturation adds warmth and richness. Heavy distortion creates aggressive tonal coloration.
What They Shape
These tools change timbre by adding frequencies that weren't in the original signal, often making digital recordings feel warmer or more analog.
3. Plugin Order: Why Sequence Matters
The order plugins appear in the signal chain changes the final sound because each plugin processes the output of the previous plugin. Probably the easiest way to demonstrate this is to add a distortion plugin to a sound, then a reverb. The reverb tail will be clean and free of distortion. However, flip the order so that the reverb comes first and then it goes into the distortion, and you’ll notice a very different result. How different? Try it out when you open your DAW next!
-
Place an EQ before a compressor: the EQ shapes the frequency content, then the compressor responds to that shaped signal. If you cut low frequencies with the EQ, the compressor doesn't react to those frequencies because they're already gone.
Place the compressor before the EQ: the compressor reacts to the full frequency range, including frequencies you might not want compressed. Then the EQ shapes the compressed signal. The compressor's behavior changes because it's processing different source material.
Neither order is correct or incorrect. They produce different results, and the appropriate choice depends on what you're trying to achieve.
-
Many producers use patterns like:
EQ → Compression → Reverb/Delay
Saturation → EQ → Compression
Gate → EQ → Compression
These patterns work often enough to be useful starting points. But they're not rules. Some situations benefit from completely different orders. Compression before EQ can work. Reverb early in the chain creates specific effects. Experimentation reveals what serves the track.
-
Think about what you want each plugin to respond to. If you want a compressor to respond only to midrange energy, place a high-pass and low-pass filter before it—or a bandpass. If you want EQ to shape the compressed character rather than the source, place EQ after compression.
This cause-and-effect thinking helps you make intentional decisions about order rather than following formulas.
4. CPU Management: Why It Matters
Plugins consume CPU. Every plugin you load uses processing power. Simple plugins (basic EQs, simple delays) use minimal CPU. Complex plugins (convolution reverbs, analog hardware emulations, synthesizers with many oscillators) can use significant CPU.
-
When your CPU can't keep up with the processing demands, you hear audio dropouts, pops, clicks, or stuttering. Playback becomes unreliable. In extreme cases, the DAW freezes or crashes.
This typically happens as sessions grow: you start with a few tracks and plugins, everything runs smoothly. You add more tracks, more plugins, layer processing, and eventually hit the limit.
-
Most DAWs show CPU usage in a meter or performance indicator. Watch it periodically as you add plugins. If it consistently runs above 70-80%, you're approaching problems. Different DAWs handle CPU load differently, but most start struggling as usage approaches maximum capacity.
-
Freeze tracks: most DAWs can temporarily render MIDI tracks or heavily processed audio tracks to audio files, disabling the plugins and virtual instruments. This frees CPU while maintaining the sound. You can unfreeze later to make changes.
Bounce to audio: convert MIDI tracks to audio permanently, or print processed audio tracks as new audio files with the processing baked in. This is permanent but frees maximum CPU.
Increase buffer size in your audio settings: larger buffers reduce CPU load but increase latency. During mixing (when you don't need low latency), raising buffer size can prevent CPU issues.
Use plugins selectively: not every track needs heavy processing. Focus processing on the most important elements. Background elements often work fine with minimal or no processing.
5. Stock vs. Third-Party Plugins
Your DAW includes stock plugins such as EQs, compressors, reverbs, delays, and more. These cover all fundamental processing needs. Most stock plugin sets are comprehensive and capable of professional results.
-
Stock plugins handle the core tasks: frequency shaping, dynamic control, spatial effects. Learning to use stock plugins well teaches you how these processes work. The skills transfer to any other plugin. A compressor is a compressor—threshold, ratio, attack, release work the same whether you're using stock or third-party.
Many professional productions use primarily stock plugins. The tools matter less than understanding what you're doing and why.
-
Third-party plugins typically offer:
Specific hardware emulations (vintage compressors, classic EQs)
Specialized workflows (different interface designs, faster operation for specific tasks)
Unique algorithms (different reverb characters, specialized processing)
These additions can be valuable once you understand what you need. If you know stock compressors well and you want a specific vintage character, a hardware emulation makes sense. If you understand EQ thoroughly and want a different workflow, a third-party EQ might speed up your work.
-
Gear Acquisition Syndrome (G.A.S.) is something we can all relate to. It is a form of procrastination. It is also the assumption that buying new tools will solve production problems or improve results. It manifests as constantly researching, buying, and collecting plugins while actual production stalls.
But new plugins don't teach you to hear better or make better decisions. They give you more options, which often creates more confusion rather than better results.
It’s easier said than done, but: learn stock plugins thoroughly before buying third-party options. When you understand a tool deeply, you'll know precisely what a different tool would provide. That clarity prevents wasteful purchases.
6. Presets: Starting Points, Not Solutions
Most plugins ship with presets, which are saved settings designed for specific applications. "Vocal Compression," "Bright EQ," "Large Hall Reverb."
-
Presets demonstrate what the plugin can do. They teach you which parameters matter for specific tasks. They provide starting points when you don't know where to begin.
Loading a "Vocal Compression" preset shows you typical threshold, ratio, attack, and release settings for vocals. You learn that vocals often benefit from moderate ratios (3:1 to 6:1) and medium attack times. This knowledge transfers to manual settings.
-
Presets are generic. They're designed for an imagined average scenario, not your specific recording. Your vocal was recorded with a different microphone, in a different room, with a different performance dynamic than whatever the preset designer used.
This means presets almost never sound optimal on your material. They might be close, but close isn't finished. Adjusting presets to fit your audio is necessary, not optional.
-
Load a preset as a starting point. Listen to what it does. Then adjust parameters to fit your material. Too much compression? Lower the ratio or raise the threshold. Too bright? Adjust the EQ. Not enough reverb? Increase the wet/dry mix.
This adjustment process teaches you how parameters interact and what changes produce what results. Over time, you'll load presets less often because you'll know how to dial in settings manually faster than auditioning presets.
Your Turn: Plugin Order Experiment
Open your workbook on page 84
***
This exercise helps you hear how plugin order affects the final sound. It demonstrates why "Signal Flow" isn't just a technical term—it’s a creative decision. Set aside 20 minutes.
Step 1: Prepare Material
Create a project with one track containing audio—a vocal, instrument, or drum loop works best. You need source material to process.
Step 2: Load Two Plugins
Load a Distortion (or Overdrive) plugin and a Reverb plugin on that track in this "Standard" order: Distortion first, Reverb second.
Distortion: Crank the "Drive" or "Gain" until the sound is noticeably crunchy or aggressive.
Reverb: Set the "Mix" or "Dry/Wet" knob to roughly 50% so you can clearly hear the echo tail.
Step 3: Listen and Document
Play the audio and listen specifically to the tail (the echo) when the sound stops. Notice that while the hit itself is distorted, the reverb tail fades out cleanly and naturally.
Write down one sentence describing the sound (e.g., "Crunchy drum hit with a smooth fade out").
Step 4: Reverse the Order
Swap the plugin positions so the Reverb comes first, then the Distortion. (Most DAWs let you simply drag plugins to reorder them in the chain).
Play the audio again. Warning: It might be significantly louder!
Step 5: Compare and Explain
Write down: Does it sound different? If yes, how?
The difference comes from what the distortion is processing. In the first order, the reverb adds space to the distorted sound. In the second order, the distortion is crushing the reverb tail itself, raising the noise floor and turning the fading echo into a "wall of noise."
Expected Outcome
Direct experience with how plugin order changes the physics of your sound. You understand that "Reverb into Distortion" creates a messy, shoegaze-style wall of sound, while "Distortion into Reverb" keeps the space clean. You can now make this choice intentionally.
Producer FAQs
-
Presets are designed for generic scenarios, not your specific recordings. Your vocal was captured with different equipment, in a different space, with different performance dynamics than whatever the preset designer used. Presets rarely fit perfectly. They provide starting points that demonstrate what's possible. Adjusting them to your material teaches you how each parameter works and trains your ear to hear what needs changing. Stopping at presets means accepting someone else's generic solution instead of optimizing for your specific situation.
-
No. Stock plugins are sufficient for professional production. Many commercially released tracks use primarily stock processing. Third-party plugins offer specialized workflows, specific hardware emulations, or unique algorithms, but these are enhancements, not requirements. Learn stock plugins thoroughly first. Once you understand them deeply, you'll know exactly what third-party tools would add. Most producers with G.A.S. own hundreds of plugins but still reach for stock tools because they never learned the expensive purchases properly.
-
Yes. Each plugin processes the output of the previous plugin. EQ before compression means the compressor responds to the EQ'd signal. Compression before EQ means you're shaping the compressed character. The difference is audible. There's no universally correct order—different sequences serve different purposes. Understanding what you want each plugin to respond to helps you choose appropriate order rather than following formulas blindly.
-
Watch your CPU meter. If it's consistently above 70-80%, you're approaching problems. More importantly, listen critically. If you can't identify what each plugin is contributing, you probably have unnecessary processing. Professionals typically use fewer plugins than beginners expect. Every plugin should have a clear purpose. If you can't articulate why a plugin is loaded, disable it and see if you miss it. Often, you won't. Heavy processing doesn't equal quality—purposeful processing does.
Quick Reference
Plugin Categories
Dynamics (compression, limiting), Frequency (EQ, filters), Time-Based (reverb, delay), Modulation (chorus, phaser), Distortion (saturation, overdrive).
Plugin Order
Sequence matters. Each plugin processes the previous plugin's output. Common starting point: EQ → Compression → Reverb/Delay. Break patterns intentionally, not randomly.
Stock vs. Third-Party
Stock plugins are sufficient for professional work. Learn them thoroughly before buying third-party options. G.A.S. (Gear Acquisition Syndrome) wastes money and delays learning.
Next Steps
Everything covered so far happens inside your computer—virtual instruments, software effects, digital mixing. This is called working "in the box." But you've probably seen studios with racks of physical gear: hardware compressors, analog EQs, outboard reverbs. Does that hardware matter, or is software sufficient?
The next lesson addresses working in the box versus using hardware. It covers what hardware actually provides, when software is genuinely limiting, and why most producers work primarily or entirely in software regardless of budget.
