Mathematica Code[edit]

time = 30;
norm = 1/Sqrt[2];

Table[
 
 tone = Play[
   norm*Sin[f*2*Pi*t],
   {t, 0, time},
   PlayRange -> {-1, 1}
   ];
 
 str = "Sine Wave " <> ToString[f] <> "Hz " <> ToString[time] <> "s" <>
    ".wav";(*Constructs a name for the tone*)
 
 Export[str, tone],
 
 {f, 10, 100, 10}
