Pick the role
Double Tight, Choir Natural, Rap Stack, and ADR Loose set the starting feel before manual tuning. Some stereo controls are still preview shaping while deeper DSP lands.
Buffle Audio / macOS developer preview
Buffle Audio Align
Preview timing moves for doubles, ADR, and backing vocals against a guide while keeping the small imperfections that make a stack feel human.
Public download is v0.3.0. Current main has post-v0.3 V1 polish pending fresh artifacts and host validation.

one job, done clearly
Line up the stack while keeping the performance alive.
Align watches the Guide and Dub, estimates a signed timing offset, scores phrase confidence, and lets you audition full preview changes or only the consonants reduced by the tamer.
studio flow
Four controls that match the way vocal stacks are made.
Trust the read
The Trust Meter names the reason: route the Guide, raise a quiet lane, keep listening for confidence, or apply a safe Delay/Advance Dub move.
A/B the change
Original, Aligned, All Diff, and Tamer modes split the full timing change from consonant-only cleanup so the preview does not hide what changed.
Keep it human
Naturalness Guardrail flags risky cleanup before print, while Consonant Tamer Lite softens unmatched Dub attacks without flattening the vowel body.
engine state
A transparent preview engine, not a black-box warper.
v0.3.0 is a developer preview, but the core path is real: CMake builds, DSP unit tests, standalone, AU, VST3, bundle archive, rough installer package, and release assets are all part of the current workflow.

release
Get the current macOS preview.
Download the macOS developer preview from GitHub Releases. The bundle zip is the cleanest testing path today; the installer package is available for local preview only and is not Developer ID notarized yet.
support
Fund the boring parts that make plugins shippable.
Signing, host compatibility passes, audio examples, and V1 polish all take time. Support helps move Align from preview to a serious daily tool.
