Een buitenaards bericht van aardse makelij

About this episode

Op 24 mei vorig jaar werd een testbericht uitgezonden vanuit een baan rond de planeet Mars. Een en ander gebeurde ter voorbereiding op de dag dat we daadwerkelijk een buitenaards signaal ontvangen. Eerder dit jaar werd de boodschap eindelijk ontcijferd.

Python script om de boodschap hoorbaar te maken op een enigszins wetenschappelijk verantwoorde wijze:

# Sonification of the TGO message.

# Hens Zimmerman, 18-11-2024.

# There exist two equal length wav files:

# 1.wav is a short beep

# 0.wav is silent


import wave


# Open and read original text version of the TGO message.

# https://github.com/BatchDrake/ASignInSpace/blob/master/Candidates/artifacts/data17.txt


with open('data17.txt') as f:

    msg = f.read()


# The whole beepy sonification will be constructed here.


data = []


# Read the two sound files into buffers.


w = wave.open('0.wav', 'rb')

zero = [w.getparams(), w.readframes(w.getnframes())]

w.close()


w = wave.open('1.wav', 'rb')

one = [w.getparams(), w.readframes(w.getnframes())]

w.close()


# Append a beep for every '1' and silence for every '0'.


for c in list(msg):

    if c == '1':

        data.append(one)

    elif c == '0':

        data.append(zero)


# Write the output file to disk.


output = wave.open('sonification.wav', 'wb')

output.setparams(data[0][0])

for idx in range(len(data)):

    output.writeframes(data[idx][1])

output.close()
