Quick Answer

Vocal Box (also branded VxBx) is Maciel Audio’s free one-plugin vocal mixing suite—not the KVRDC 2026 roundup, and not an Auto-Tune tutorial. KVR’s 11 August 2026 winners post: Vocal Box placed 2nd of a record 56 entries and takes 20% of the prize fund; Windows and macOS; VST3, AU, and AAX.[1] The KVR product card lists it as Free, version 1.0.11, copy protection none, and points downloads at AudioLoom, which prices VxBx at $0.[2][3] KVR user reviews on that product page flag high CPU; test in your host before you rebuild a session around it.

This Page Is Vocal Box. It Is Not the KVRDC 2026 Roundup.

Stay here for Vocal Box (VxBx) by Maciel Audio: what the free vocal suite actually contains, which formats KVR lists, where the $0 download lives, and the 2nd-place KVRDC 2026 result. Do not use this file as a 56-plugin contest shortlist.

The related KVR Developer Challenge 2026 article covers the field, voting, and other keepers. This article is the dedicated Vocal Box review those related slugs exist to avoid duplicating.

It is also not pitch-correction school (use the related Auto-Tune / Melodyne pages), and not a replacement chart for discontinued Accusonus ERA voice-repair tools. As of September 2026, the primaries are KVR’s winners post, the Vocal Box product card, and Maciel’s AudioLoom page.[1][2][3]

KVRDC 2026: 2nd Place, 20% of the Prize Fund

KVR’s 11 August 2026 winners announcement: Vocal Box by Maciel Audio is a “Vocal Mixing Suite,” available for Windows and macOS in VST3, AU, and AAX, and takes 2nd as the next-highest placed entry after Scintillate. It receives 20% of the prize fund.[1]

The same post: KVRDC 2026 is the tenth free-for-all, with a record 56 entries. The quoted product line: Vocal Box combines essential vocal processing into one streamlined tool so you can clean up, push forward, and finish vocals without rebuilding the same plugin chain every session.[1]

Contest hub dates (as listed on the 2026 challenge page): submission deadline 6 July; download and voting 7 July; winners announced 11 August. Use that hub for the live entry list; this page does not re-rank the other 55 titles.[4]

Fact on the cited KVR pagesWhat it isWhat you should not assume
Placement2nd of 56; 20% of the prize fund[1]Not 1st (Scintillate). Not a paid “pro” SKU because it placed.
LicenceKVR product card: Free. AudioLoom: $0[2][3]Not a time-limited demo on those two pages.
FormatsVST3, AU, AAX on Windows and macOS[1]Not CLAP/LV2/Linux on the winners post.
Copy protection (KVR card)None[2]Not an iLok-required Antares-class tuner.

One Insert: Noise, Spank, Aggro, Then Built-in FX

Maciel’s AudioLoom page frames VxBx as the shortcut to bigger, more upfront vocals: clean, control, and push home-recorded vocals without a complicated plugin chain. The KVR blurb matches that “everything your vocal needs before you start mixing” pitch.[3][2]

AudioLoom’s own module copy, in order: an intelligent Noise Suppressor first, so room noise, computer hum, and headphone bleed do not snowball through the rest of the chain; Spank, a custom vocal processor that blends aggressive compression with analog-inspired saturation and tonal shaping on a single control; Aggro, harmonic bite aimed at screams, shouts, and dense rock/metal stacks; then a creative block with two classic Radio effects plus Spooky modulation.[3]

Time-based FX on the same page: Slap (tight mono slapback); Delay A (1/8-note); Delay B (wider 1/4-note, pairable with Shifter for pitch modulation and stereo width); Plate or larger Room reverb. Each effect has dedicated high-pass and low-pass filters. That is vocal prep and polish in one GUI—not graph-mode retune, and not spectral repair.[3]

  • Noise Suppressor AudioLoom: clean the noise floor before compression and saturation so home-studio hiss does not get louder with every stage.[3]
  • Spank The centre control: aggressive compression + analog-inspired saturation + tonal shaping. Presence, not a published Auto-Tune algorithm.[3]
  • Aggro + Radio / Spooky Harmonic grit for dense productions; Radio filters and Spooky for intro/breakdown textures without leaving the plugin.[3]
  • Slap / Delay / Plate-Room Built-in slapback, 1/8 and 1/4 delays (Shifter on Delay B), plate or room, each with HPF/LPF. KVR reviewers still asked for deeper delay/reverb edits—treat these as starter sends, not a dedicated space designer.[3][2]

VST3 / AU / AAX. Confirm the Live Card Before You Install.

KVR winners + product card: Virtual Effect for macOS and Windows; Audio Units, VST 3, and AAX; 64-bit only. Windows card on KVR: Windows 10 or higher, AAX and VST3, at least 8 GB RAM (16 GB recommended), at least 200 MB free on the OS drive. macOS card: Mac OS X 10.15 or higher, Intel and Apple silicon, AAX/VST3/AU, at least 8 GB RAM (16 GB recommended), at least 400 MB free.[1][2]

AudioLoom’s system block is slightly different: AAX/VST3/AU, 64-bit Mac/PC, Mac OS X 10.15+ (Intel native | ARM native), Windows 10, at least 4 GB RAM (16 GB recommended), at least 200 MB free. Cite both pages; do not invent a third RAM figure. Product version on the KVR card at fetch: 1.0.11. Copy protection: none.[3][2]

AudioLoom’s DAW list (host versions they name): Ableton Live 11+ (AU, VST3); Bitwig 4+; Cubase 13+ (VST3); Digital Performer 11+; FL Studio 23+ (VST3); GarageBand 10+ (AU); Logic Pro 10+ (AU); Pro Tools 12+ (AAX); Studio One 5+ / Fender Studio; Reaper 6+ (VST3); Cakewalk Next by BandLab (PC VST3). Recheck that list on the live page if your host is older.[3]

KVR Users Flag CPU. This Is Not Auto-Tune or ERA.

The KVR product page showed an average user rating of 2.57 from 7 reviews when fetched. Several of those reviews (July–August 2026) call out high CPU even when the vocal “gets there instantly,” and one notes a failed 1.0.11 installer on that user’s Windows machine. Those are user reports on KVR, not a lab benchmark on this page—load one instance in a disposable session and watch your meter before you commit a mix template.[2]

Placement is not a CPU warranty. 2nd of 56 means KVR voters ranked it there; it does not mean the plugin is light, or that it replaces a split chain of denoise + compressor + de-esser + tuner + send FX.

Out of scope here: Auto-Tune Pro X 10.1 ARA2, Auto-Tune vs Melodyne for rap, Accusonus ERA legacy replacements, and the rest of the KVRDC 2026 field. Use the related slugs. This file stops at Vocal Box as free one-plugin vocal prep.

Install from AudioLoom. Test CPU. Then Mix.

This checklist is only how to get a legal free instance running. It is not a vocal-mix course. Confirm version and host notes on the live KVR card before you change a session template.[2][3]

  1. Download from AudioLoom or the KVR product/downloads tab
     KVR lists the product as Free and links audioloom.com/maciel-audio/vxbx. AudioLoom shows $0. Prefer those two over random mirrors.[2][3]
  2. Match format to host: VST3, AU, or AAX
     64-bit only. Windows 10+; macOS 10.15+ Intel and Apple silicon on the cited cards. AudioLoom names Live 11+, Logic 10+, Pro Tools 12+, FL 23+, Cubase 13+, Reaper 6+, Studio One 5+ among others.[2][3]
  3. Insert one instance on a dry vocal in a disposable project
     Start with Noise Suppressor, then Spank, then only the FX you can hear. AudioLoom’s pitch is “before you start mixing,” not “replace the mix bus.”[3]
  4. Watch CPU before you stack doubles
     KVR user reviews repeatedly flag load. If one insert spikes the buffer, keep Vocal Box as a print/prep stage or skip it—do not assume 2nd place means realtime-cheap.[2]
  5. Do not treat this page as tuning or contest coverage
     Pitch tools live on the related Auto-Tune pages. The 56-entry field lives on the related KVRDC 2026 shortlist. This file stops at Vocal Box.

If you need a free vocal prep plugin you can quote, start from verified software rather than treating a KVR contest rank as mix school. Plugg Supply free processing is 0; the free tier is ready non-premium archives only, and paid plans add processing and Telegram delivery.

Frequently Asked Questions

Is Vocal Box by Maciel Audio free?
Yes on the cited pages. KVR’s product card lists Vocal Box as Free with no copy protection. AudioLoom prices VxBx at $0. It was a KVR Developer Challenge 2026 entry.[2][3]
Is VxBx the same plugin as Vocal Box?
Yes. KVR’s product title is Vocal Box - Vocal Processor; the same card and winners post also use VxBx. AudioLoom sells it as VxBx by Maciel Audio. Same developer, same suite.[2][3][1]
What place did Vocal Box take in KVRDC 2026?
2nd. KVR’s 11 August 2026 winners post: Scintillate 1st, Vocal Box 2nd (20% of the prize fund), among a record 56 entries. That is contest rank, not a CPU or mix-quality warranty.[1]
Which plugin formats does Vocal Box support?
VST3, Audio Units, and AAX, 64-bit, on Windows and macOS, per KVR’s winners post and product card. Those pages do not list CLAP, LV2, or Linux for this entry.[1][2]
Does Vocal Box tune pitch like Auto-Tune or Melodyne?
No on the cited Maciel/KVR copy. AudioLoom describes noise suppression, Spank dynamics/saturation, Aggro harmonics, Radio/Spooky, slap/delay/reverb—not graph-mode pitch. Use the related Auto-Tune pages for tuners.
Why do KVR reviews mention high CPU?
Because several user reviews on the KVR product page (July–August 2026) report heavy CPU, even when they like the sound. The page average at fetch was 2.57 from 7 reviews. Treat that as user report: test one instance in your host.[2]
Where should I download Vocal Box?
From Maciel’s AudioLoom product page (kvraudio.com also links it) or the KVR product downloads tab. Contest files also lived on the KVRDC 2026 hub. Prefer those over third-party mirrors.[3][2][4]
Is this article the KVR Developer Challenge 2026 best-free-plugins roundup?
No. This is a dedicated Vocal Box review. The 56-entry shortlist, voting rules, and other keepers live on the related KVRDC 2026 article.
