Waveform Characteristics

Amplitude: Represents the volume of a sound wave, indicating the strength or intensity of the sound being produced.
Frequency: Defines the rate at which oscillations occur in a sound wave, measured in Hertz (Hz), with cycles of positive and negative amplitude.
Velocity: Refers to the speed at which sound waves travel through a medium, influencing how quickly sound reaches an observer.
Wavelength: The distance between successive points in a wave cycle, crucial for determining the tone and pitch perceived.
Phase: Describes the relationship between two or more waveforms, affecting their interaction; can result in constructive interference (amplification) or destructive interference (cancellation).
Harmonic Content: Involves the presence of additional frequencies (partials) that accompany the fundamental frequency, shaping the timbre or quality of the sound.
Envelope: Characterizes the dynamic changes in sound levels over time, detailing how a note evolves from attack to sustain to release.
