# Audio recordings: sources and licences

Pitch Riot's music and most of its sounds are synthesized in the browser (src/audio). The stadium crowd uses the field recordings
below. They load after the page has loaded (src/audio/sfx.js `loadRecordings`), never as part of the initial bundle.

Every file in `crowd/` was cut, faded, level-matched and encoded to 96 kbps MP3 (48 kHz) for Pitch Riot on 22 Oct 2026 with FFmpeg 7.0.2;
the ambience bed also got a broad -6 dB cut around 2.8 kHz and -4 dB from 5 kHz and the applause a broad -8 dB cut around 3 kHz, a 7.5 kHz low-pass and a gentle peak compressor (a close-miked hall made a little more outdoor). Those edits are ours; the
recordings belong to their authors under the licences below. The attribution is shown on the imprint page (`impressum.html`).
