Bundled third-party audio recordings
------------------------------------

The following recordings ship with Okul Zili and were supplied by the
project owner, who has confirmed permission to redistribute them with the
application (see SES-KAYNAKLARI.md for sources and details):

- The student, teacher, and recess school-bell recordings from the prior
  school installation (since 0.6.0: the announced student and teacher bells
  and the unannounced bell; the short block-transition bell is derived from
  the unannounced bell recording).
- The Ministry of National Education (MEB) İstiklâl Marşı recordings
  (vocal and band versions), added in 0.6.0.
- The Presidency of the Republic of Türkiye İstiklâl Marşı recordings
  ("for untrained voices" and "original composition, vocal"), added in 0.6.0.
- The combined moment-of-silence + İstiklâl Marşı sequence and the
  moment-of-silence "Ti" tone, added in 0.6.0.
- The 10 November two-minute siren + İstiklâl Marşı sequence, added in 0.6.0.
- The three AFAD civil-defence alert recordings (yellow warning, red alarm,
  black/CBRN alarm), added in 0.6.0.

The original source files these WAV recordings were converted from (MP3/WMA/
M4A files under src/zilsesleri/ in the source repository) are kept only for
regeneration, are not shipped in installation packages, and are covered by
the same permission confirmation.

Responsibility for the redistribution confirmation of these recordings rests
with the project owner. The application's PolyForm Noncommercial license
covers the application code only and does not extend to these recordings.

All other sounds (drill sirens, the general emergency tone, the announcement
chime, the fallback beep, the two-minute 10 November siren slot, and the
recess-music arrangements synthesized from public-domain compositions by
J.S. Bach and L. van Beethoven) are generated by the application itself and
are not copies of third-party recordings.
