Hello,
can anybody help mew with this please?:
I need play a very special function: Play[f(t) Sin[440 2 Pi t], {t, 0, 1}]
where f(t) is defined as:
InterpolatingPolynomial[
{{0.05, 0.1099}, {0.1, 0.1099}, {0.15, 0.1099}, {2, 0.1099}, {2.5,
0.2404}, {3, 0.2404}, {3.5, 0.2404}, {4, 0.2404}}, x]
i used too set sample rate in play on 20 and I have a suspicion that mathematica is not samping in 0.05,0.1 .... becouse:
Play[(0.1099` + (-0.05` +
t) (0.` + (-0.1` + t) (0.`/
+ (-0.15` + t) (0.`/
^2 + (-2 + t) (0.018888406426400346`/
^3 + (-2.5` +
t) (-(0.027072084931302032`/
^4) + (-3 + t) (0.020795344947353474`/^5 - (
0.011164174391133095` (-3.5` + t))/
^6))))))) Sin[440 2 Pi t], {t, 0, 0.4},
SampleRate -> 20]
gives error:
Sound::ssnf:sample points did not evaluate to real numbers.
please try it in your mathematica: i only want a different intensity for different time in my synthetis as you can see. THANK YOU
