Visibility kit
Shareable angles
Different audiences need different entry points. The catalog can act as the master hub, while each outreach route links directly to the most relevant product, service or repository.
Lead with the free premaster checklist when the topic is release delivery, then share a relevant public audio pack only when it solves the discussion at hand.
Lead with the free theme plugin, then point technical users to the repository-backed release and delivery tools. This fits directories and developer forums better than the sample packs.
Use the free premaster checklist as a practical release-delivery resource. Use the catalog and mixing preview only when they are relevant to the artist or label.
Build status
The evidence chain
A repository, tested artifact, deployment, storefront and delivered purchase are separate milestones. This index reports the strongest confirmed state without collapsing the steps between them.
Project files or repository exist.
A bounded build has been checked.
A remote version may still be private.
A public listing and checkout are visible.
The customer receives the correct artifact.
Context matters
Engineering, software, services and independent product development.
Gabriel’s solo music and live-performance identity. Audio products carry it only when explicitly developed under that name.
The duo project shared with Gabriel’s brother. Its work is not presented as Gabriel’s solo output.
The independent label and curatorial platform, with its own catalogue and lifecycle controls.
About the work
Gabriel García Alonso is a Berlin-based sound engineer, music producer and live performer. This site documents the products, utilities and repositories he develops around production, release readiness, artwork, metadata and reliable handoff.
Human listening and professional judgement stay central. Technical tools remain local, private and non-destructive where their purpose allows. Claude and Codex are used as development collaborators; authorship, artistic direction and release decisions remain with Gabriel and the relevant project.
