Pure tones |
only one pure sine wave |
Sine wave at 100 Hz is located in SoundSamples\TestSounds |
Harmonics tones |
several tones (sine waves) whose frequencies are multiples of a fundamental frequency |

Noise |
White |
uniform energy distribution over the whole frequency band |
White noise is located in SoundSamples\TestSounds |
Pink |
uniform energy distribution per octave over the whole frequency band |

Modulated sound |
Amplitude Modulation |
variation of the amplitude at a given frequency, with a certain depth (amplitude of the modulation) |
Sine 1000 Hz modulation 4 Hz is located in SoundSamples\TestSounds |
Frequency Modulation |
variation of the instantaneous frequency of the signal at a given frequency (of modulation) and at a given deviation (around the frequency of the original sine) |
Sine 1000 Hz modulation 70 Hz is is located in SoundSamples\TestSounds |
