Sound qualities supporting distinctions between sources beyond overall level, duration and pitch. Spectral shape, temporal envelopes and their changes contribute; no single scalar need describe every timbral difference.
Timbre, often referred to as the "color" or "quality" of sound, is the characteristic that allows us to differentiate between different sources of sound, even if they are producing the same pitch and loudness. It encompasses the unique differences in sound quality that distinguish one instrument or voice from another. Several factors contribute to timbre, including: 1. **Harmonics**: The presence and amplitude of overtones (harmonics) produced along with the fundamental frequency.
