🚨 per a lovely chat with
npub15d4j4hsae4n3f6qhztzwq5hnertdzq80zjtl77ujqh7e6l9gx75qtpfwp5 (npub15d4…fwp5), i've learned something that i didn't previously know: 24-bit audio data is signed! meaning: it doesn't have 24 bits of audio data, it has 23. the leftmost bit is a "sign bit," indicating whether the data word's value is positive or negative (0 if positive, 1 if negative)
this is weirdly hard to confirm by googling ... i finally found it in The Scientist and Engineer's Guide to
Digital Signal Processing
