What is Deck
From digital files to cassette-ready WAV
Deck is a desktop app built for people who still love the ritual of recording to tape. Pick your formulation and tape length, drop in a track or a whole folder, and let Deck handle loudness, EQ, and headroom so your music survives the transfer to analog.

How is this different from normal mastering?
Deck targets cassette transfer: tape formulation profiles, HF headroom, true-peak limiting, and optional tape-aware saturation — so your digital master survives recording to analog and playback on a deck or walkman.
Can I build a full mixtape from a folder?
Yes. Import a folder, arrange tracks in the editor, check whether everything fits your tape length, then prepare and export.
