Wav audio problem

Projects General Guidance
1

Hello,
I am trying to add a speaker in my project and play a MP3 audio. I transformed it into a WAV. At the bottom of void setup, where there are two question marks, what do I write? I've tried looking for different tutorials, and I don't know if it's the file number or title, etc.

#include <SD.h>
#define SD_ChipSelectPin 10
#include <TMRpcm.h>
#include <SPI.h>
int SD_ChipSelectPin;
TMRpcm tmrpcm;

void setup ()
{
  tmrpcm.speakerPin=9;
  pinMode(11,OUTPUT);
  Serial.begin(9600);

  if(!SD.begin(SD_ChipSelectPin)) {
    Serial.println("SD fail");
    return;
  }
  tmrpcm.setVolume(30);
  tmrpcm.play("??");
}

void loop() {
}

Thank you

Take a look at the TMRpcm reference page, and Github site.
