Perceptual quality corresponding to waveform?

Perceptual quality corresponding to waveform?

• A. Timbre
• B. Pitch
• C. Loudness
• D. Duration

Answer: (A)

Timbre is the perceptual quality that lets you tell sounds apart by their color or tone, beyond pitch and loudness. This quality comes from the waveform’s harmonic content and how the sound starts and ends over time. Different waveforms carry different overtones and envelope shapes, so even when two tones share the same pitch and are played at similar loudness, they sound distinct—one might be pure and mellow, another bright or buzzy. Pitch is about how high or low the sound is (the fundamental frequency), loudness is about how strong the sound is (amplitude), and duration is how long the sound lasts. So the waveform itself primarily shapes timbre.
