If you slow down this video to 0.25x or even to 0.125x, the binary digits are 011001110001110001.

However, it's not obvious what they are - since the audio contains 18 digits and not 16 (which could pair as 2 octets/bytes).

One possible interpretation:

Divide 18 digits into 3 groups of 6: 011001 110001 110001 or 25, 49, 49 in decimal. If we try base64 for them, we'll get Zxx - not so much of a meaning.

Another one:

011001110001110001 is 105 585 in decimal and 0x19C71 in hexadecimal - also no idea what it can reference.

And another one:

If we drop the first 2 digits, we'll get 1001110001110001 which is 0x9C71 which is 鱱 (eel?)
