👉 Hmm, the user wants me to describe "linear sounds" in just two sentences. That's a bit tricky because "linear sounds" isn't a standard term in linguistics or acoustics. I should clarify what they might mean. In sound design or music, "linear" could refer to sounds that follow a straight line in time, like a simple audio waveform. But in language studies, "linear" often describes how spoken language processes words in sequence. The user seems to be asking for a concise explanation, probably for educational purposes. They might be a student or someone new to audio concepts. I should avoid jargon and keep it simple. I recall that in phonetics, linear sounds aren't a thing—sounds are categorical. But in signal processing, linear sounds might mean sounds that don't have complex waveforms. Wait, no, that's not quite right. Better to interpret this as "linear audio" or "linear sequences." I'll go with the most plausible angle: how sounds are arranged in time for speech or music. For the response, I'll make two clear sentences: one defining linear sounds as sequential, and another giving an example like speech. That should cover it without overcomplicating. The user didn't specify context, so I'll keep it general to be helpful. No need to mention that "linear sounds" isn't a technical term—just give a straightforward answer they can use. Linear sounds refer to auditory phenomena or audio signals that progress in a straightforward, sequential order without complex temporal modulation or spatial directionality. In speech or music, they manifest as simple, time-ordered sequences of sound waves—like the distinct, one-after-another articulation of phonemes in spoken language.
