SampledSoundList

SampledSoundList[{a₁, a₂, ...}, r]
is a sound primitive, which represents a sound whose amplitude has levels a_i sampled r times a second.

SampledSoundList[{list₁, list₂, ...}, r] 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:

ListPlay generates a SampledSoundList containing normalized amplitudes:

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