Hear BeatMaster before installing it

Four excerpts from Kidoku, a Yoruhazed project created with Suno and then mastered with the current BeatMaster build. Both sides are loudness-matched at −18 LUFS, with no artificial volume advantage.

02 / Why

Automatic mastering without sending tracks to the cloud

01

Serious local engine

BeatMaster runs on your computer: loudness, true peak, crest, stereo and tonal analysis, then a deterministic mastering chain designed for release-ready files.

02

Album and batch first

Master a single, EP or album with cross-track cohesion, streaming/CD/club targets and Clean, Warm, Punchy, Analog or Transparent modes.

03

Auditable delivery

The Studio tier highlights what SaaS tools hide: deterministic ZIP, SHA-256 manifest, Ed25519 signature and client QC report proving what was delivered.

03 / How

The new Spetrouchka path

  1. 01

    Download the trial

    Spetrouchka no longer processes audio online. The site exists to download BeatMaster, hear demos and manage your license.

  2. 02

    Master locally

    Open BeatMaster, drop files, choose a mode and loudness target. No upload, no server cost, no music file stored by us.

  3. 03

    Deliver cleanly

    Export WAV/MP3, album batch, QC report and signed bundle depending on your edition. The site only keeps your account, invoices and downloads.

04 / Pricing

Software, not a render counter

BeatMaster is sold as a desktop app: trial first, license after.

05 / FAQ

Questions

Does Spetrouchka still master online?

No. The pivot is intentional: Spetrouchka becomes BeatMaster's storefront and customer account. Mastering happens inside the desktop app.

Why sell a desktop app instead of a SaaS?

Because audio stays private, server cost per render drops to zero, and BeatMaster was already designed as a reliable local tool instead of a cloud worker.

Do my music files leave my computer?

No. BeatMaster works locally: the site only keeps what is needed for accounts, licensing, invoices and downloads.

How is this different from LANDR or a classic plugin?

LANDR sells a cloud render. BeatMaster targets a local workstation with album batch, QC measurements, reproducible exports and signed bundles for auditable delivery.

Windows or macOS?

Windows first, because the project is developed and verified on Windows. macOS matters commercially but needs a dedicated build/signing chain.

When will the trial be available?

After the first signed builds and A/B demos rendered with BeatMaster. Sign up to receive private access.
