Does Processing only load audio files at 44.1KHz? I have an mp3 at 48KHz loaded to my sketch. I set the Sound object to 48KHz. My sound card is at 48KHz. But the file is loading at 44.1 and the slow playback confirms.

```auto
import processing.sound.*;

Sound sound;
SoundFile file;

void setup()
{
  sound = new Sound(this);
  sound.sampleRate(48000);
  
  file = new SoundFile(this, "Feel My Body feat. Xav A.mp3");
  file.play();
  println(file.sampleRate());
}

void draw()
{
}

```

Printed to the console:

```auto
44100

```

I guess that you set sound.sampleRate(48000) because you have other sounds at 48 KHz.  
A solution is to open your 44.1 KHz file with [Audacity](https://www.audacityteam.org/) (or other similar programs), to change the “Project Rate (Hz)” to 48000 Hz in the bottom left of the window, and finally to save it by exporting in your wanted format.
