Are you on the menu ? <| sep |> This was a derisive reference to the ultraleft demand for safe spaces which even the NYT picked up on . <| sep |> Thank you for sharing , it gives perspective on the what is happening for us not directly affected . I hope you stay safe . <| sep |> I was in line behind a lady at Walmart who offered to pay for a man ' s purchases . He politely thanked her , but declined her offer . She was FURIOUS . Started yelling at him for ruining her day and said he was a horrible person who would probably end up in hell . She ended up ruining everyone ' s day . <| sep |> It might be helpful to think of a waveform as just a way of thinking about or graphing the actual compressions rarefactions that hit our ears . For instance , you don ' t think about the transient pop from plugging in a lead in terms of a waveform or a sum of pure frequencies or superposition or harmonics even though all of those concepts still apply . You just think of it as a single strong compression of air travelling in a wave from the speaker to your ear . Waveforms are a conceptual tool to help us think about , visualise , and manipulate sound . The sound that hits your ear is a waveform . The voltage across a wire is a waveform . The movement of a speaker cone is a waveform . The audio signals that combine in a mixer are their own waveforms , and their combination is a waveform itself .
