Let S be an endless string which is a concatenation of every binary counting in succession, starting from zero all the way to infinity (without left zero-padding):

S = 01101110010111011110001001101010111100110111101111...
(from concatenating 0, 1, 10, 11, 100, 101, 110, 111, 1000, 1001, and so far)

Let S' be a set of every sequential group of octets (8 bits) from string S, which can be represented as a base-10 number (between 0 and 255), like so:

S'_2 = [01101110, 01011101, 11100010, 01101010, 11110011, 01111011, ...]
S'_10 = [110, 93, 226, 106, 243, 123, ...]

I'd create an audio wave file whose samples are each octet from S'_10 as 8-bit audio samples, using a really low sampling rate (such as 8000 Hz or even 4000 Hz).
That sound, that particular sound, is what I'd transmit to the cosmos: the binary counting, something with a detectable pattern (although it'd be not so easily recognizable, but something that one could readily distinguish from randomness noise).

Hommarju feat latte masterpiece

Jellyfish Jam of course.

Y'all are way too nice. I'm pumping a 60Hz square wave right into that thing at max volume.

free bird solo 🤙

Cheri Cheri lady, living in devotion!

Really gonna hit that 16hz pipe right!

Id freak out about having to make a choice and then just blurt out souvlaki space station because it seems like a safe bet of sm i like at high volumes.
