Coming in Kadrack Capture · V2

Your records deserve better than Audacity.

Kadrack Capture is a companion tool that walks you through ripping a vinyl side from start to finish. Record live while the record plays, or import a file you already have. Automatic track splitting, audio fingerprinting, tags. No session files. Just your records, in your library.

Vinyl, CD, and cassette
Automatic silence detection and track splitting
Audio fingerprinting and metadata editing
Writes directly to your Kadrack library and your folder structure

The ecosystem

Built to grow with your collection.

Three stages that fit together. Buy the Player today; everything else slots in as it ships. Beta supporters get founder pricing on the whole family.

V1 Available in beta

Kadrack Player

Player, library, DAP sync. Everything a serious local music collection needs.
V2 In development

Physical Release: Capture + Mixtape

Capture brings your records into your library — vinyl, CD, and cassette, analog to digital. Mixtape writes real cassette mixtapes back out of it: Side A, Side B, automatic level matching. The full circle.
V3 Planned

Kadrack Home Server

Your library, always on. Autorip, mobile companion, whole-home access.

I built Kadrack for the people who never stopped buying records.

Who rip their CDs lossless. Who still look at every second-hand walkman. For everyone who loves to own their music and just want software that gets out of the way.

A new generation is rediscovering what it feels like to actually own the music they love. We're building the software that belongs in that world — and the three tools that go with it.

Frequently asked

Things people keep emailing us.

Will Kadrack ever go subscription?

No. One-time purchase. You own the version you buy forever. New major versions may be paid upgrades; minor updates and fixes are free.

Which platforms are supported?

macOS 13+ (Intel / Silicon), Windows 10/11, and modern Linux distributions (Ubuntu 22.04+, Fedora 38+, Arch). An mobile companion app (iOS / Android) is planned.

Can I import my existing iTunes / Apple Music / Plexamp library?

Yes. We import .xml, .m3u, .m3u8, and any folder of files with embedded tags. Play counts, ratings, and date-added preserved where present.

What about streaming?

Kadrack is a local-first player. We have no plans to integrate with any streaming services out of principle.

When can I actually use it?

Private beta begins Q3 2026 for the Player. Waitlist signups get access in cohorts, starting with DAP owners and vinyl rippers (we want your real libraries stress-testing the scanner). Public 1.0 targets early 2027. Capture follows.
