Elementary Sounds

This section references the elementary sounds and their representations.

Basic sounds

Features

Playback

Sine wave

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

No sample available

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

Pink noise is located in SoundSamples\TestSounds

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
