Drop in EAS audio — it demodulates the SAME AFSK bursts, decodes the header to plain English, gives you the tone audio + a spoken voice message, and can re-encode what it decoded. Add your own custom audio before/after the announcement.

3 · Audio outputs
Tones are re-encoded from the decoded data (decode → encode). The voice plays live through your speakers via browser TTS — it can't be baked into a download.
4 · Custom pre / post announcement
Full sequence: your pre-audio → silence → SAME headers ×3 → attention signal → spoken voice → EOM ×3 → your post-audio. The .wav has everything except the live voice.
5 · Decode → Encode
Re-encoded straight from the decoded data — bit-identical SAME, ready to transmit or archive.
