A waveform refers to

• a plot of a signal over the [time domain]
• a graphical depiction of pressure changes at a point in space over time
  • depicts pressure / time
  • regular pattern of pressure variations, exhibiting a loss of energy over time

Example: a digital [sine] waveform

Types

Within audio, the term "waveform" refers to several fundamental types of waves that are usually depicted within the time domain:

• [sine waves]
• [square waves]
• [triangle waves]
• [sawtooth waves]
