It’s officially summer now because the internet is being torn apart.

A viral audio clip posted on Twitter Tuesday sent everyone into a tizzy trying to determine whether the robotic voice is saying “Yanny” or “Laurel.”

Much like the black and blue (or white and gold) dress of February 2015, the difference seemed aribitrary, but one expert told the Daily News that it all depends on the frequency levels; both words are actually in the recording.

Cory Choy, a sound engineer at Silver Sound in New York, isolated two separate aspects of the audio, which only includes levels below about 6,000 hertz; the human ear can hear between about 20 hertz and 20,000 hertz. Anywhere below 1,300 hertz plays “Laurel,” while anything above that plays “Yanny.”

The source of the audio can change the voice too, he said. Using headphones or better speakers is more likely to include bass, which would result in “Laurel” over “Yanny.”

While altering frequencies is mostly just fun, Choy said it’s been used in cryptography to hide messages in a certain part of the audio spectrum.
