Hi,

I'm trying to use Manipulate[] with AudioGenerator to generate a Sine wave for a range of audio frequencies, and for a given span of time. I must not be understanding this correctly because I can control frequency and audio volume, but cannot seem to pick a specific length of time if I am also selecting frequency. All of this is for generating short sine waves between 100 and 3000 Hz, and wanting to pick a duration of between 0.25 seconds and 2 seconds.

Here is an example where I cannot get length of time to change:

Manipulate[
 AudioGenerator[
  {"Sin", freq, length}, SoundVolume -> volume],
 {freq, 100, 3000},
 {length, 0.7, 100.0},
 {volume, 0.01, 0.08}
 ]

What am I missing? How do I manipulate time plus frequency plus volume?

If it matters, I'm using Mathematica 11.3.
