SampledSoundList

is a sound primitive that represents a sound whose amplitude has levels

sampled r times a second.

SampledSoundList yields sound on several channels. If the lists are of different lengths, silence is inserted at the ends of shorter lists.

Generate a sampled sound signal, sampling twice per period of a 1000 Hz signal:

Out[1]=

ListPlay generates a SampledSoundList containing normalized amplitudes:

Sampling a signal less than twice the largest frequency leads to aliasing:
