It supports CLAP, VST3, VST2, Audio Unit v2, AAX, LV2, and FLP formats on Windows 7 or later, macOS 10.15 or later, and Ubuntu 22.04 or later.

The maker states there is no subscription or update fee. Session compatibility may be broken across major version changes.

Graillon 3 offers vocal-focused pitch tools and effects, with extra capabilities in its Full Edition. Check operating system and plug-in format requirements, and consider the stated risk to sessions across major version changes.

It suits vocalists and audio producers seeking pitch correction, shifting, and vocal effects in a plug-in. The Full Edition may suit users who want its additional modulation, tuning, doubling, and presets.

Overview

Auburn Sounds Graillon 3 is a vocal-processing plug-in for pitch correction and vocal shaping. It is best suited to producers who want correction, pitch and formant shifting, and vocal-oriented effects in one plug-in. The free edition covers the core tools; the Full Edition adds modulation, tuning, and doubling.

Its appeal is the combination of pitch control and built-in effects across Linux, macOS, and Windows. The main trade-off is that sessions may not remain compatible across major version changes, a concern for projects that must stay usable through upgrades.

Key features

Graillon 3 offers pitch shifting, formant shifting, and pitch correction, with three pitch engines: G2, G3, and I1. Real-time correction and MIDI pitch control give producers options for steering or shaping a vocal, while the pitch-shift range is 12 semitones. That defined range suits vocal work but is not an unlimited transformation span.

The built-in compressor, gate, chorus, preamp, and bitcrusher are described by Auburn Sounds as tuned for vocals and adding no latency. Keeping these effects alongside pitch tools can make Graillon 3 a practical vocal insert; the set is aimed at vocals rather than broad, general-purpose processing.

The Full Edition adds Pitch-Tracking Modulation (PTM), keyboard tuning, and a vocal doubler. It also includes 20 additional presets, among them Maqam scales, robotic voices, and vocal effects. Those extras make the paid edition more compelling for producers who need modulation or doubling, while the free edition remains more complete than a basic correction-only option.

Pricing

Graillon Free Edition costs nothing. It includes pitch shifting, formant shifting, pitch correction, all three pitch engines, and the built-in effects. It omits PTM, vocal doubling, and keyboard tuning, so it suits users who want the core vocal tools without paying for those additions.

Graillon Full Edition costs $29, paid once, billed $$29 or more; it is shown on sale from $38.67. This is a one-time purchase, not a subscription, and adds PTM, vocal doubler, microtonal tuning, and 20 additional presets. It is the better fit when those features matter, but the free edition already includes the main pitch tools and effects.

Auburn Sounds says the Full Edition has no subscription, phone-home behavior, or update fee. Purchases go through resellers acting as merchant of record, which handle payment and billing data; Auburn Sounds says it keeps no order database.

Platforms

The user guide lists CLAP, VST3, VST2, Audio Unit v2, AAX, LV2, and FLP formats for Windows 7 or newer, macOS 10.15 or newer, and Ubuntu 22.04 or newer. The Full Edition page names Pro Tools, Cubase, Logic, Live, and FL Studio among supported host software. Check the required operating system and plug-in format against your setup before buying or moving a project.

The guide says sessions remain compatible across minor version changes, but compatibility may break across major ones. That makes version changes a material consideration for long-lived or shared sessions.

Who it's for

Graillon 3 is a strong fit for vocal producers seeking correction, pitch and formant shaping, and a compact set of vocal effects, especially if they want to begin with a free edition. The Full Edition makes more sense for users who specifically need PTM, keyboard tuning, or a vocal doubler. It is less suitable for anyone who needs confidence that sessions will remain compatible across major version changes.

Pros and cons

• Pros: The free edition includes pitch correction, shifting, formant control, three engines, and built-in effects, so the core vocal workflow does not require an upgrade.
• Pros: Full Edition adds PTM, keyboard tuning, doubling, and 20 extra presets for a one-time purchase rather than a subscription.
• Pros: The maker says it runs no analytics, advertising, tracking pixels, or profiling, and its website stores nothing about visitors.
• Cons: Full-only features include PTM, vocal doubling, and keyboard tuning, so users who need them must pay for the upgrade.
• Cons: Session compatibility may break across major version changes, which can complicate upgrades to established projects.
• Cons: Format and minimum operating-system requirements vary by setup, so compatibility should be checked before committing to a workflow.

Verdict

Choose Graillon 3 if you want vocal-focused pitch and formant tools with useful built-in effects, and value a free edition that includes the core processing. Upgrade when PTM, keyboard tuning, doubling, or the added presets justify a one-time purchase. Look elsewhere if major-version session compatibility is essential to your workflow.
