- Description: Nectar 4 Standard at $199 is the right buy for most vocal and spoken-word mixing; Advanced earns its extra $100 through Auto-Level, Breath Control and component plug-ins. Review scores, CPU load, Audiolens' retirement, Sound Forge support and who should skip it.

**Nectar 4 is worth buying if you mix vocals or spoken word and want one plug-in that analyzes the voice and builds a full processing chain for it. Standard is the edition most people should buy, at $199 in iZotope's US store on October 29, 2026\. Advanced costs $299 and earns its extra $100 only through Auto-Level, Breath Control and 13 separate component plug-ins. Skip it if you already run a vocal chain you trust: the reviews agree that Nectar saves time, not that it beats careful manual processing.**

The published verdicts back that up. MusicTech scored Nectar 4 9/10, Bonedo gave it 4.5 out of 5, Sound On Sound listed no cons at all, and heavy CPU load is the one complaint that keeps coming back. I would buy Standard unless you build vocal chains plug-in by plug-in in a DAW template. Standard already has the full module set, Melodyne 5 essential, Relay and Vocal Unmask.

- **Buy Standard** for podcasts, voice-over, dialogue and most song vocals.
- **Pick Advanced** if you want Auto-Level evening out the level before compression, Breath Control, or each module as its own plug-in.
- **Take Elements** only if $55 is your ceiling and adjusting the Assistant's result is all you plan to do.
- **Skip it, or run the 10-day trial first,** if you already have a vocal chain you trust.

## What iZotope Nectar 4 is (and is there a Nectar 5?)

Nectar 4 is iZotope's vocal channel strip. One main plug-in, which iZotope's manual calls the mothership, listens to a voice and sets up a chain of modules for it: EQ, compression, de-essing, pitch correction, saturation, reverb, delay and more. Nectar is iZotope's vocal suite, next to RX for repair, Ozone for mastering and Neutron for the rest of the mix; the [iZotope guide hub](https://soundforgepro.com/izotope/) maps which one handles which job.

There is no Nectar 5\. Nectar 4 has been on sale since September 2023, and [iZotope's product downloads page](https://www.izotope.com/pages/product-downloads?ref=soundforgepro.com) lists 4.2.0 as the current version of all three editions; [iZotope's Nectar release notes](https://www.izotope.com/pages/release-notes/nectar?ref=soundforgepro.com) date that update August 18, 2026\. iZotope announced on July 2, 2026 that it is joining Boris FX, and [iZotope's post on joining Boris FX](https://www.izotope.com/community/blog/joining-boris-fx?ref=soundforgepro.com) says existing products, licenses and subscriptions stay active.

Against Nectar 3, the "What's new in Nectar 4" section of iZotope's product page names Voices for harmonies, Auto-Level for steady level and Backer for background singers, plus 13 component plug-ins in Advanced. [MusicTech's Nectar 4 review](https://musictech.com/reviews/plug-ins/izotope-nectar-4-brings-valuable-updates-alongside-some-unexpected-creative-tools/?ref=soundforgepro.com) read the update as "refinements and upgrades to specific modules rather than an overhaul" and called the upgrade cost "a little steep". I wouldn't pay for the Nectar 3 to 4 update unless Auto-Level, Voices or Backer is the reason. The update costs $99 to Standard or $149 to Advanced.

## Vocal Assistant: what it decides and what you still control

Vocal Assistant listens to the vocal and builds the whole chain for you. It's in all three editions, but it runs only in the main Nectar 4 plug-in, not in the component plug-ins. [The Vocal Assistant chapter of iZotope's Nectar 4 manual](https://docs.izotope.com/nectar4/en/assistant/index.html?ref=soundforgepro.com) says it needs audio playing while it listens, and that clips shorter than 20 seconds need loop playback turned on.

The analysis sets the input level, a character EQ and dynamics, the vocal register for Voices and Backer, subtractive EQ for clarity, the De-esser for sibilance, a compressor for output level and a subtle reverb. After that you steer the result with six Intent Controls instead of dozens of module parameters:

- **Shape** moves the character EQ (EQ 2) toward the target curve on the tonal balance display.
- **Intensity** sets the threshold, ratio, attack and release of the first compressor.
- **Width** sets the output width of the vocal.
- **FX** controls the Reverb, Delay and Dimension modules.
- **Voices** and **Backer** blend in harmonies or background singers.

Relearn runs the analysis again, which is what you want after swapping in a different take.

![Nectar 4 Vocal Assistant controls: a Shape knob marked EQ toward the target, an Intensity knob marked first compressor, a Balanced target menu over a display with the vocal curve and the target curve, an FX pad, a Width slider, a Voices and Backer switch and Relearn marked analyze again](https://soundforgepro.com/content/images/2026/10/nectar-4-assistant-target.webp)

Shape pushes the character EQ toward the target curve, Intensity drives the first compressor, and Relearn runs the analysis again on a new take.

Reviewers rate the Assistant as a starting point, which is the right way to use it. Sound On Sound called it "a very easy and effective point of entry". Bonedo found it reliable at telling singing, rap and speech apart, and advised experienced users to go straight to the individual modules. My rule is simple: let the Assistant pick the chain, then open each module and judge it by ear before you trust it on a final mix.

## Reference matching after Audiolens

Every edition can steer the Assistant toward a reference vocal. Custom Referencing and the Target Library are part of Vocal Assistant in Elements, Standard and Advanced, and the "+" button in the Target Library uploads your own reference to guide Nectar's character EQ. Matching is narrower than the word suggests. MusicTech's reviewer points out that it won't copy saturation, reverb or delay from the reference; it only makes tonal changes to one EQ module.

[Audiolens](https://soundforgepro.com/izotope-audiolens/), the separate iZotope app that Nectar 4 was designed to pair with for references, is on its way out. [iZotope's Audiolens support notice](https://support.izotope.com/hc/en-us/articles/47669983352333-Support-Notice-for-Audiolens?ref=soundforgepro.com) says it has been sunset from the catalog. Existing owners can keep using it, it gets critical maintenance updates until March 18, 2027, and its referencing and target-library features stay compatible with all three Nectar 4 editions. The online Nectar 4 manual is still the 4.0.0 edition from 2023 and describes Audiolens as fully compatible, so read its Audiolens pages as history.

For new reference work I'd use [Tonal Balance Control 3](https://soundforgepro.com/tonal-balance-control-3/), because that's where iZotope moved the Audiolens referencing workflow; iZotope Pro includes it and iZotope Plus doesn't. When a vocal only needs to lean toward a reference's tone, Nectar's own "+" upload does that in every edition without another app.

## The modules that matter: Auto-Level, Voices, Backer and the rest

Most edition decisions come down to a handful of modules and two bundled extras. Here's what each one does.

**Auto-Level** sits at the start of the chain and evens out vocal level before the compressor sees it. Its Learn button runs a short analysis pass to set an RMS target. MusicTech and Bonedo both singled it out for evening out vocal dynamics, and it's the module I'd miss most on speakers or singers who swing between quiet and loud passages.

**Voices** builds harmonies from pitch-shifted copies of the vocal, in 11 styles. Elements gets those styles through the Assistant; the full module, with up to eight voices, a MIDI mode for playing harmonies in real time and custom styles, is in Standard and Advanced. Set the song's key first: with "No Key" selected, only the Octave and Unison styles work. For a simple doubled lead rather than harmonies, iZotope's free [Vocal Doubler plug-in](https://soundforgepro.com/izotope-vocal-doubler/) does that single job.

**Backer** turns the lead into background singers with singing voice conversion. It has eight personas, each trained on a different person's voice. The eight personas are in every edition, while the full module, with your own uploaded a cappella, pitch and formant shift and tone control, is Standard and Advanced. iZotope notes that Backer was trained only on English-language singing. Reviewers split on its sound, as the test results below show.

![Eight Backer persona cards named Raquel, Alex, Una, Kate, Myth, Johnny, Stacey and Carter, with Raquel selected, beside notes that all editions get the personas and Standard and Advanced add vocal upload, pitch and formant shift and tone control](https://soundforgepro.com/content/images/2026/10/nectar-4-backer-personas.webp)

All eight personas are in every edition; your own upload, pitch and formant shift and tone control need Standard or Advanced.

**Melodyne 5 essential** comes with Standard and Advanced, not Elements, for note-by-note pitch and timing edits alongside Nectar's own Pitch module. Whether essential is enough for a lead vocal is answered in [Melodyne essential vs assistant](https://soundforgepro.com/melodyne-essential-vs-assistant/).

**Breath Control** is a separate plug-in for breath noise, and it's Advanced only. Sound Forge users can also [edit breaths by hand on the waveform](https://soundforgepro.com/edit-breaths-sound-forge/), which costs nothing extra.

**Vocal Unmask** reduces the masking between the vocal and other tracks, and it needs Relay, Nectar or Neutron inserted on the masking track. iZotope's comparison table disagrees with itself on its edition: its detailed rows for Unmask mode, Unmask with Relay and Neutron, Dynamic mode and Sidechain mode tick Standard and Advanced, while the table's short feature summary ticks Advanced alone. The Standard product page also promises vocal unmasking, so I'd count on it in Standard. Relay, also included with Standard and Advanced, lets Nectar talk to other iZotope plug-ins in the session. Standard and Advanced also end the chain in a brickwall, zero-latency limiter and let you reorder modules; Elements can't reorder them.

**Component plug-ins** are the biggest practical difference in Advanced: 13 modules as separate plug-ins (EQ, Auto-Level, Breath Control, Backer, Pitch, Compressor, Voices, De-Esser, Saturation, Reverb, Gate, Delay and Dimension), in VST3, AUv2 and AAX only. They let you save a fixed vocal chain in a DAW template. The Intent Controls don't come along, because they exist only in the main plug-in's Assistant view.

## Test results: what published reviews and measurements show

The composite result is positive, and it has two limits worth knowing before you lean on it. It counts six sources: three named editorial reviews, a plug-in database entry, a November 2024 r/audioengineering thread and Thomann customer reviews. Only two publish a named reviewer's score, and both work out to 9 out of 10, so each appears below as that source's own result rather than as an average. Every review covered Nectar 4.0 in 2023 or 2024.

| Review                       | Published         | Version and setup                         | Result                                                                                                                                                                                        |

| Sound On Sound (John Walden) | April 2024 issue  | Advanced                                  | [No score; cons listed as "None"](https://www.soundonsound.com/reviews/izotope-nectar-4-advanced?ref=soundforgepro.com)                                                                       |

MusicTech's 9/10 came with a verdict of strong value for new buyers, and Sound On Sound said you get "great bang for that buck" while calling the Advanced component plug-ins "a most welcome development". Bonedo's 4.5 is the editorial score; the reader average on the same page isn't. A Dubspot plug-in database entry also shows a 7.8/10 site score, but with no named reviewer, date or method it counts here only as a reading on workflow and CPU, not as a score.

Backer gets the sharpest split. Sound On Sound found that it "works remarkably well". MusicTech ran a batch of vocals through it, heard robotic-sounding results with artifacts and glitches, and listed "can sound quite artificial" as a con. Bonedo's reviewer wasn't impressed by the sound either and called it essentially an ordinary formant and pitch-shifting tool. MusicTech's other cons are smaller but practical: "uninspiring reverb sounds" and no ducking on the reverb and delay.

User opinion points the same way as the experienced reviewers. In a [November 2024 r/audioengineering thread on Nectar 4 Advanced](https://www.reddit.com/r/audioengineering/comments/1gz8up2/what%5Fare%5Fyall%5Fopinions%5Fof%5Fnectar%5F4%5Fadvanced/?ref=soundforgepro.com), several commenters framed Nectar as a fast-turnaround starting point rather than a precision tool, although two of the eight people visible in the thread said they hadn't used it.

### CPU load and latency

The only CPU number in the composite is a single 2023 reading. In Bonedo's review, one Nectar 4 instance with a few modules active pushed one Logic CPU thread to 25% on a MacBook with a 2.4 GHz 8-core Intel i9 and 64 GB of RAM, and the fan became audible. That's one Intel machine, one host and version 4.0.x; it gives no figure for Apple silicon or for any other host. MusicTech lists "CPU hungry with multiple modules running" among its cons, and the Dubspot entry flags CPU load with several instances in a session.

Bonedo also reported a sync problem. Toggling bypass, or switching the tuning module off and on, caused high latency and pushed the vocal out of sync with the track until playback was stopped and restarted. None of the release notes for 4.0.1, 4.1.0 or 4.2.0 lists a CPU or performance change, so the 2023 CPU findings have no documented fix. Plan on one Nectar instance per vocal, and render finished vocals in a heavy session instead of stacking live instances.

### Store ratings

Store ratings sit apart from the reviews because nobody controls who rates, when, or on which version.

| Store            | Product                                 | Rating       | Ratings |
| ---------------- | --------------------------------------- | ------------ | ------- |
| iZotope US store | Standard and Advanced (one shared pool) | 4.6 out of 5 | 621     |
| iZotope US store | Elements                                | 4.0 out of 5 | 60      |
| Thomann          | Advanced                                | 4.0 out of 5 | 6       |
| Plugin Boutique  | Advanced                                | 4.4 out of 5 | 8       |

iZotope's pool is vendor-hosted, shared between the Standard and Advanced pages and undated, so it may include reviews of earlier Nectar versions. The [Thomann reviews of Nectar 4 Advanced](https://www.thomann.de/intl/izotope%5Fnectar%5F4%5Fadvanced.htm?ref=soundforgepro.com) break down as three five-star, two four-star and one one-star; that one-star review, from January 2025, calls it useless for people who already mix well.

Taken together, the composite says Nectar 4 buys speed and a consistent starting point for a voice. Reviewers trust the Assistant and Auto-Level more than Backer, and the weak spots are CPU load and the price of updating from Nectar 3\. Nothing in it shows Nectar beating a carefully built manual chain.

## Editions and prices: which Nectar 4 to buy

Standard at $199 fits most buyers, Advanced at $299 fits template builders and anyone fighting uneven levels, and Elements at $55 fits a strict budget. Three differences decide most purchases; upgrade paths, education pricing, sale history and the rent-versus-buy math are in the [Nectar 4 Elements vs Standard vs Advanced comparison](https://soundforgepro.com/nectar-4-elements-vs-standard-vs-advanced/).

| Edition  | US store price | Who it fits                                    |
| -------- | -------------- | ---------------------------------------------- |
| Elements | $55            | Beginners who only want the Assistant's result |
| Standard | $199           | Podcasts, voice-over and most song vocals      |
| Advanced | $299           | Engineers building vocal chains in a template  |

- **Elements to Standard** buys the full editable modules, module reordering, Melodyne 5 essential, Relay and Vocal Unmask. Elements stops at adjusting what the Assistant built.
- **Auto-Level** is Advanced only on iZotope's comparison table, on [iZotope's Nectar 4 Advanced page](https://www.izotope.com/products/nectar-advanced?ref=soundforgepro.com) and in the manual. The "Key features" lines on the Standard and Elements pages also name Auto Level, which contradicts iZotope's comparison table, so I wouldn't count on it below Advanced.
- **Breath Control and the 13 component plug-ins** are Advanced only as well, and they're what template builders pay the extra $100 for.

Buy the edition you'll need in a year: every later step up, from Elements or from Standard, costs more than buying that edition outright.

Renting is the other route, at US prices from the same day: [iZotope's subscriptions page](https://www.izotope.com/pages/subscriptions?ref=soundforgepro.com) lists iZotope Plus at $15 a month or $150 a year with Nectar 4 Standard, and iZotope Pro at $25 a month or $250 a year with Advanced and Tonal Balance Control 3, each with a 7-day free trial. The plug-ins turn read-only when a subscription ends, so for a vocal tool you'll keep using I'd buy rather than rent.

## System requirements, hosts and the free trial

Nectar 4.2.0 needs macOS Sonoma 14.7 or later on Intel or Apple silicon, or Windows 10 (22H2) or Windows 11 (24H2), and iZotope ships it only as 64-bit AU, AAX and VST3, with no VST2 build. [iZotope's Nectar Advanced download page](https://www.izotope.com/pages/product-downloads/nectar-advanced?ref=soundforgepro.com) gives the trial 10 days without restriction; after that, Demo mode inserts silence at regular intervals.

Sound Forge isn't on iZotope's supported host list. Both editions on the [Sound Forge pricing page](https://www.vegascreativesoftware.com/sound-forge/pricing/?ref=soundforgepro.com) support third-party VST2, VST3 and ARA plug-ins, so Nectar 4's VST3 build can load there, but iZotope makes no promise about how Vocal Assistant or any other Nectar feature behaves inside Sound Forge. I'd treat Nectar in Sound Forge as a bonus on a license you bought for a supported DAW, not as the reason to buy it. If Nectar doesn't show up in your host or won't authorize after installing, start with the [iZotope Product Portal and authorization fixes](https://soundforgepro.com/izotope-product-portal-authorization-install-fixes/).

## Who should buy Nectar 4, and who should skip it

Your kind of work decides the edition, so here are the common cases in order.

**Podcasts, voice-over and dialogue for video:** buy Standard. It has the full EQ, Compressor, De-Esser and Gate modules, module reordering and the zero-latency limiter, which covers a spoken-word chain. Voices and Backer don't matter for this work. Only a talker who keeps drifting between quiet and loud makes Auto-Level worth the step up.

**Singer-songwriters finishing demos:** Standard again, for the full Voices module with up to eight voices and MIDI mode, the full Backer module and Melodyne 5 essential. The reviews split on Backer's sound, so hear it in the trial before it sways the purchase.

**Engineers who build chains in a template:** Advanced, for the component plug-ins that drop single Nectar modules into a saved template, with the Intent Controls left behind in the main plug-in.

**Experienced mixers with a chain they trust:** skip it, or trial it first. That's where the Reddit thread, Bonedo's advice to go straight to the modules and the one-star Thomann review all land.

![Five rows matching work to a Nectar 4 edition: podcasts, voice-over and dialogue to Standard, song vocals and harmonies to Standard, template chains and Auto-Level to Advanced, a $55 budget to Elements, and a trusted vocal chain to skip or trial first](https://soundforgepro.com/content/images/2026/10/nectar-4-buy-or-skip.webp)

Find the row that matches your work; the 10-day trial settles the rest.

When the choice is between a vocal suite and a mix suite, [Nectar vs Neutron](https://soundforgepro.com/nectar-vs-neutron/) explains which modules overlap and when you need both. For vocals that need repair before polish, the guide to the [best iZotope plug-ins for vocals](https://soundforgepro.com/best-izotope-plugins-for-vocals/) puts RX, Nectar and the free tools in order by job. Sound Forge users who only need to tame harsh esses can do it in the editor itself, as shown in [reducing sibilance in Sound Forge](https://soundforgepro.com/reduce-sibilance-sound-forge/).

## Verdict: is Nectar 4 worth it?

My verdict: Nectar 4 Standard at $199 is the right buy for most people who mix vocals or spoken word. It gives you the Assistant, the full modules, Melodyne 5 essential and Vocal Unmask without paying for extras you may never open. Advanced at $299 is worth it if you build vocal chains in a template or want Auto-Level evening out level before compression. Elements makes sense only as a $55 Assistant-only entry, and an experienced mixer with a trusted chain can keep the money. Before you pay, run the 10-day trial on one of your own vocals in your own host and keep an eye on the CPU meter while you do.
