Ten voices, ten windows, one clock — and each is a different cipher. Type a word into any box and it is enciphered in that voice's own way: the lyre turns letters into a pentatonic line; the dùndún reads it as gliding Yorùbá tones; the bàtá runs it through ẹ̀nà (the real vowel-echo cipher) and strikes it; the two-tone drum renders it as binary; the ultrasonic flings it past the hearing line as near-ultrasonic FSK; the keystroke leaks it as key-clicks at each char's acoustic fingerprint; the fan hums it off an air-gapped machine as blade-pass FSK; the adversarial rides it on a 20 kHz carrier only a machine hears; the numbers station reads it as five-digit groups; and the glowworm recovers it from a flickering LED. Give each its own word and its own speed, angle & volume — then play them together: a layered cipher, split by sound and style, all through the ternary echo. The whole cipher series, sounding at once.
