LITBackmasking is deliberately recording sound backwards onto a track (the Beatles used reversed tapes in 1966). The 1980s claim that hidden reversed messages are unconsciously perceived and influence listeners did not hold up: controlled studies (e.g., Vokey & Read, 1985, cited from memory) found no such effect. Listeners "hear" words mainly when told what to expect (priming, pareidolia).

COMPUTEDA short synthesised chirp-and-tone phrase is generated, reversed sample by sample, and reversed again. Reversing twice gives back the identical buffer, and the reversed spectrum's magnitude equals the original's. Play forward or backward (Web Audio, quiet). The spectrogram is drawn in q.d colours.
