How to Play (3 sec drum loop .wav loaded into PSRAM) using Granular instead of call play any Player??

[charnjit]

if we loaded a drum loop .wav to psram teensy 4.1 . Addres SMP_addr[0] size sizes[0].
can i play it in seamless loop by granular functions (not call any player , playMemory etc) ????
if yes (how to play it with specific Speed [Time stretching] without affect Pitch from begining of file.......with code example )
if no .... How to call it other way from begining of file.
i am complicated with use of granular.beginFreeze(); and its parameter according to my 3sec drum loop.
Please Reply..........................Thank you

after calling in void setup()

  granular1.begin(SMP_addr[0], sizes[0] / 2);
  granular1.setSpeed(1.0); // Normal speed
  granular1.beginPitchShift(1.0); // Normal pitch
  granular1.beginFreeze(200);

my drum loop not start playing . but it is started by caling by :

playArray[0]->playWav(SMP_addr[0]);

And after playing following code does not make changes in playback speed

   granular1.setSpeed(1.5);
   granular1.beginFreeze(200);

if Developer or expert of Granular teensy reading this post , please reply .. correct way to use of it to stretching time without pitch.
thank you..

@charnjit: Have you tried the granular example (Files > Examples > Audio > Effects > Granular) ?? Does it work for you, as expected ??

Yes tried but not working... I have tried in this thread/post#5

https://forum.pjrc.com/index.php?threads/how-to-add-granular-to-audio-playback-to-control-speed-in-realtime-without-affect-pitch-of-sample.77749/

I want to get code used below, read and try myself . i hope, i will get better result
, please open below link by Nic N

yes ...Mark J Culross ..in example (Files > Examples > Audio > Effects > Granular) example only affect Pitch of running Audio file ,but not PLayback speed (time stretching).
above video you are seeing in post#4 by Nic N. this is what i am searching for. In video Playback speed being changed without affect pitch. i am curious to see code what is running on his teensy. it will help me a lot. but in description of video , there is no link openable for code. plaese help me to get running code in teensy ask him.
changing Playback Speed
thank you.....
