A body of work

Seven seasons of scripted fiction, told one episode at a time.

Each season stands as a self-contained novel for the ears — but together they form a single, decade-long conversation about place, memory, and the people who refuse to be mapped. Browse the catalogue below, or start with the latest.

How an episode is made

Built like a short film for the ears.

Each episode passes through four overlapping stages, each averaging around eleven weeks. The same writers' room methodology has been taught at nine universities since 2019.

  1. I

    The writers' room

    A six-week scripted development cycle with a rotating ensemble of playwrights, dramaturgs and the show's lead writer. Every script is read aloud, in full, three times before any recording begins.

    Avg. 6 weeks · 4 — 6 writers per room

  2. II

    Field recording

    Sound design begins on location. Our senior team travels with a curated library of 1,200+ original ambiences recorded across nineteen countries, and returns with new material for almost every episode.

    Avg. 2 weeks · 19 countries on file

  3. III

    Ensemble recording

    Cast sessions are run as live, in-room performances — never voice-isolated, never stitched from solo reads. A single episode may carry fifteen to thirty speaking voices plus a foley bed.

    2 — 3 days · up to 30 voices per ep.

  4. IV

    Hand editing

    Every cut is made by hand by senior sound designer Inês Faro in our -68 dB Lisbon studio, working from a hand-drawn cue sheet and a printed script. The room is silent for the final mix.

    Avg. 3 weeks · 1 supervisor per episode

A note from the studio

We make fiction for listeners, not for advertisers. Every episode is paid for by the people who'll press play — so it answers to them, and to no one else. No mid-roll interruptions. No host-read swaps. No “brought to you by.” Just the story, the sound, and the time it takes to tell them properly.

— Tomás Reis, founding director · written for the spring 2026 season
