EQ plugins
15 plugins, sourced from developer spec pages and cross-checked where needed. This is a spec-based comparison, not a set of hands-on reviews.
1Pro-Q 4
FabFilter
Flagship digital EQ. Up to 24 bands, switchable dynamic and linear-phase modes, built to do almost anything.
- 24 bands plus dynamic EQ on every one of them, an unusually deep amount of control packed into a single plugin
- Switches between zero-latency, linear-phase, and Natural Phase modes on the fly, so you're not locked into one trade-off between speed and phase accuracy
- The spectrum analyzer and EQ Match tools make it fast to actually see what you're doing to a track as you work
- At $199, it's a serious investment for an EQ plugin, worth it mainly if you'll actually use its deeper modes and per-band dynamics
- So many modes and per-band options that newcomers often just use a fraction of what's here
2TDR Nova
Tokyo Dawn Records
Free parallel dynamic EQ. Four bands, each with its own compressor built in.
- Completely free, and still does real dynamic EQ, a feature plenty of paid plugins charge a premium for
- Each of the four bands has full compressor controls attached, so it can act as a tone shaper, not just a static filter
- Runs on basically anything, Windows 7 and OS X 10.9 are supported, unusually old system requirements for a modern plugin
- Four bands total is thin for detailed, surgical work, fine for general corrective moves but tight for anything more involved
- No mid/side mode confirmed, so mastering engineers reaching for stereo-image control will need a different tool alongside it
3Manley Massive Passive EQ
Universal Audio
Vari-mu tube EQ modeled on Manley's iconic hardware. Four bands, all character.
- Faithful passive tube modeling of a hardware unit that regularly shows up on world-class mix bus chains, harmonic richness most digital EQs don't attempt to model
- Runs natively on Windows or Mac with no UAD hardware required, unlike older Universal Audio plugins that were locked to their DSP cards
- Simple four-knob-per-band layout keeps big analog-style moves fast, no menu diving
- Four bands total is a broad-strokes tool, not built for narrow, surgical cuts
- No confirmed mid/side mode, so dedicated stereo-image work on a mix bus will need a separate tool
SplitEQ
Eventide
Splits transient from tonal content, then lets you EQ each separately.
- Structural Split technology separates transient (attacks, sibilance) from tonal (sustained harmonic) content, letting you cut harshness without dulling the note underneath it
- 8 bands with independent mid/side or left/right panning per band, on both the transient and tonal streams, effectively doubling your control points
- Solves problems that otherwise need two or three separate plugins stacked together
- No traditional dynamic EQ mode, the split-stream approach covers similar ground differently, which means the workflow doesn't map onto EQs you already know
- At $149 it's priced like a flagship tool but does one very specific job, not a general-purpose replacement for your everyday EQ
Kirchhoff-EQ
Three-Body Technology
Precision-obsessed digital EQ. 32 bands, 117-bit internal processing, 32 built-in vintage EQ models.
- 32 fully parametric bands plus 32 emulated vintage EQ curves in one plugin, a huge amount of raw firepower in one place
- 117-bit internal processing is a real outlier spec, built specifically to avoid the quantization noise that shows up under heavy cascaded EQ moves
- Dynamic processing and full mid/side routing on every band, not bolted on as an afterthought
- At $99, it's a meaningful spend, worth it mainly if you'll actually use the extra precision and 32-band depth
- That much precision and that many modes make it a slower plugin to learn than something simpler
SSL E-Channel
Waves
SSL 4000 E console channel strip. Four-band EQ bundled with the original compressor and gate.
- Licensed modeling of the actual SSL 4000 E console EQ, the sound behind a huge number of classic mix bus and channel chains
- You get the console's compressor and gate in the same plugin, so at $33 it's most of a channel strip, not just an EQ
- Waves' huge user base means presets, tutorials, and third-party guidance are easy to find
- It's bundled with dynamics processing whether you want them or not, if you only need the EQ section you're still loading the whole strip
- No VST2 support and no confirmed mid/side mode, limited format and routing flexibility
bx_digital V3
Brainworx
Dedicated mid/side mastering EQ. 11 bands per channel plus a full dynamic EQ module.
- Built specifically for M/S mastering work, with a dedicated M/S Recording decoder most mixing-focused EQs don't offer
- 11 fully parametric bands per channel plus a separate dynamic EQ module, a huge amount of total control surface
- Multi-mono, stereo, and M/S operation in one plugin covers mastering workflows that would otherwise need two or three separate tools
- At $299 list, it's a premium mastering tool, not an impulse buy for a single mix
- All that mastering-specific routing is overkill if you just need a channel EQ for a single track
Claro
Sonnox
EQ built around seeing frequency masking across your whole project, not just one track.
- The Mix view shows every Claro instance across a project at once, built specifically to catch frequency masking between tracks that a single-track view can't show you
- Three distinct views (Produce, Tweak, Mix) separate broad tonal shaping from precise surgical work, rather than cramming both into one dense interface
- AAX Native, AU, and VST3 support covers every major modern host without needing legacy VST2 compatibility
- At $139.99, it's a meaningful spend for a single-purpose EQ, worth it mainly if the cross-track masking view is something you'll actually use
- No VST2 support at all, a problem if you're on an older host that hasn't moved to VST3
EQ4
Maag Audio
Musical, low-phase-shift EQ built around Maag's signature Air Band.
- The Air Band control is the reason people buy this over a surgical EQ, it adds high-frequency lift without the harshness a normal shelf boost introduces
- Exceptionally low phase shift across all six bands keeps transients intact through big analog-style moves
- At $49.99 it's an accessible price for an analog-modeled EQ with a genuine hardware pedigree
- No dynamic EQ and no confirmed mid/side mode, so it's a coloring tool to reach for alongside a more flexible EQ, not instead of one
- Six fixed-purpose bands is restrictive if you need narrow surgical cuts, this plugin is built for broad, musical moves, not precision repair
Marvel GEQ
Voxengo
Free 16-band linear-phase graphic EQ, mono, stereo, or mid/side.
- Completely free and linear-phase, avoiding the phase smearing a minimum-phase EQ can introduce on aggressive moves
- 16 fixed bands plus full mid/side support at no cost, hard to beat for a mixing or mastering utility EQ
- Straightforward graphic-EQ layout makes broad tonal balancing fast, no per-band menu hunting
- No dynamic EQ mode, and fixed graphic-EQ bands are less precise than a fully parametric EQ for narrow surgical cuts
- Being free and from a small developer, it gets less visibility and community troubleshooting than a major commercial release
Morph EQ
Minimal Audio
Draw-and-morph EQ. Animates filter movement instead of setting static curves.
- Lets you draw and morph filter paths over time instead of setting one static curve, a genuinely different workflow from a typical EQ
- Mid/side and single-channel routing per filter point at an accessible $49 price
- 100+ presets mean the animated movement is usable immediately, not just a blank canvas you have to design from scratch
- No dedicated dynamic EQ mode, and the motion-based approach doesn't map onto a typical corrective mixing workflow
- It's node/path-based rather than a fixed number of bands, which makes it harder to reason about total control points the way a fixed band count would
Pultec Passive EQ Collection
Universal Audio
Three classic Pultec tube EQs in one bundle: EQP-1A, MEQ-5, and HLF-3C.
- Component-level modeling of three distinct passive tube units, a lot of vintage EQ character in one purchase
- Runs natively on Windows or Mac, no UAD hardware required
- The classic Pultec trick of boosting and cutting the same frequency at once for that famous low-end lift is built in and ready to use
- It's three narrow-purpose units bundled together rather than one flexible EQ, you're often stacking two or three instances to cover what a single parametric EQ does in one
- At $149 list, it's a premium price for what amounts to three narrow, vintage-specific tools rather than one general-purpose EQ
Sie-Q
Soundtoys
Three-band EQ modeled on a vintage Siemens broadcast unit. Simple, opinionated, fast.
- Modeled on the Siemens W295b, a broadcast EQ with a reputation for adding air and smoothness rather than sounding clinical
- Just three bands and a built-in saturation character, one of the fastest ways to dial in tone by ear without menu diving
- Compact interface makes it a fast first reach for vocals or a mix bus, minimal setup time
- Three bands is a genuinely low count, it's not built for detailed corrective work, pair it with a more flexible EQ for that
- No dynamic EQ or confirmed mid/side mode, purely a tone-shaping tool rather than a problem-solving one
Slice EQ
Kilohearts
Cheap, unlimited-band digital EQ with steep up to 96 dB/oct filters.
- $79 gets you unlimited bands and filters as steep as 96 dB/octave, sharper slopes than most EQs typically offer
- Mid/side mode is included at this price point, not something every budget EQ bothers to include
- Plugs into Kilohearts' Snapin ecosystem, so it can sit inside Multipass or Snap Heap for modulation most standalone EQs can't do
- No dynamic EQ mode, so anything that needs frequency-dependent compression will need a separate tool
- The Snapin-first design means some of its more interesting tricks require pairing with other Kilohearts tools, not obvious from the standalone plugin alone
smart:EQ 4
sonible
AI-assisted EQ that matches your track to a target tonal profile.
- Smart:filter technology analyzes your audio and suggests tonal balance automatically, a genuinely different starting point than manually drawing a curve
- Multi-track cross-channel processing can address frequency masking between instruments at the same time, not just one track in isolation
- Dynamic EQ behavior and full mid/side processing are included, and it's often available below its $129 list price during sales
- Handing tonal decisions to an algorithm means less hands-on control than a fully manual parametric EQ, engineers who want to shape every curve by ear may find it gets in the way
- Profile-based matching depends on having a good reference or preset, results can vary more than with a hand-drawn curve
