How to slow down audio with minim?

Hi, I’m using a song and I want it to slow down but continue playing slower from the same point when clicked when I click on an alcohol bottle (which will imply that the character is drunk) Any help?

did you check on the MINIM examples?
/Synthesis / tickRateExample
/Synthesis / flangerExample

both might be usable

It sounds like TickRate is the kind of “slow down” that you want.

The TickRate UGen can be used to control the generation rate of the UGen that is patched to it. It is equivalent to slowing down or speeding up a record player. With a rate of 1, the patched UGen will come through normally, but 0.5 will half as fast and sound an octave lower, whereas 2 will be twice as fast and sound an octave higher. Minim : : TickRate

As @kll suggested, here is the example:

github.com

ddf/Minim/blob/main/examples/Synthesis/tickRateExample/tickRateExample.pde

/**
  This is an example of how to use a TickRate UGen to control 
  the tick rate of another UGen, in this case a FilePlayer. <br/>
  A TickRate will tick the UGen patched to it at a rate relative 
  to the normal tick rate. So a TickRate with a value of 1 
  will simply pass the audio. A TickRate with a value of 2 
  will tick the incoming UGen twice as fast as normal. 
  If the value of TickRate is ever set to 0 or lower, 
  it will simply generate silence and not tick its incoming UGen at all. 
  This is because there isn't a way to tell a UGen to tick backwards.
  <p>
  Slide the mouse left and right in the window 
  to control the playback rate of the loop.
  <br/>
  Hold 'i' to make TickRate interpolate between actual sample values 
  (this will remove the "crunch" when at rates less than 1).

Can this work for samples? While this works with filePlayer and looping I’m not understanding how to patch it in with loadSample and Trigger.
