Play¶

Builds a sound object whose amplitude is the given function of the time variable (in seconds). The result is a Sound object, so it reports Head -> Sound and — in the visual hosts (the Woxi Playground and Woxi Studio) — renders a playable audio widget.

$ wo 'Head[Play[Sin[2 Pi 440 t], {t, 0, 1}]]'
Sound

Options follow the time iterator. SampleRate sets how many samples per second the amplitude function is synthesized at (8000 by default):

$ wo 'Head[Play[Sin[2 Pi 440 t], {t, 0, 1}, SampleRate -> 2^13]]'
Sound

An argument after the iterator that is not an option leaves the expression unevaluated:

$ wo 'Play[Sin[t], {t, 0, 1}, 5]'

Play::nonopt: Options expected (instead of 5) beyond position 2 in Play[Sin[t], {t, 0, 1}, 5]. An option must be a rule or a list of rules.
Play[Sin[t], {t, 0, 1}, 5]
