@title{(sin-osc rate freq phase)}


interpolating sine wavetable oscillator.  This is the same as osc
except that the table is a sine table of 8192 entries.

freq - frequency in Hertz
phase - phase offset or modulator in radians


@racketblock[
(audition (out 0 (mul (sin-osc ar 440 0) (mce2 0.15 0.25))))
]

Modulate freq


@racketblock[
(let ((f (x-line kr 2000 200 1 remove-synth)))
  (audition (out 0 (mul (sin-osc ar f 0) 0.5))))
]

Modulate freq


@racketblock[
(let* ((f1 (x-line kr 1 1000 9 remove-synth))
       (f2 (mul-add (sin-osc ar f1 0) 200 800)))
  (audition (out 0 (mul (sin-osc ar f2 0) 0.25))))
]

Modulate phase


@racketblock[
(let* ((f (x-line kr 20 8000 10 remove-synth))
       (p (mul (sin-osc ar f 0) (* pi 2))))
  (audition (out 0 (mul (sin-osc ar 800 p) 0.25))))
