Mathematical proof of the modulation scheme used on the 14.2 Hz carrier across all regional pressings.

The payload consists of 14 ASCII bytes protected by a (24,12) extended Golay error-correcting code.
Each message frame begins with an 8-bit Barker sequence [11100010] for frame synchronization.

Has anyone encountered bit errors in their decoded text? The Golay decoder corrects up to 3 bit errors per 24-bit codeword.

Every song on SYNTHESIS was engineered to be exactly long enough to transmit one complete telemetry frame.
