Arduino Uno: Synchronous playback of .wav files from SD Card

Using Arduino Audio
1

Hi, was wondering if there is a library for synchronous playback of .wav files from a microSD card, am currently using the TMRpcm library, which works great, but does not support asynchronous playback.

Hardware I am currently using:

Arduino Uno

microSD Card Reader:
Sparkfun breakout board for microSD transflash

3.5mm jack connected to earphones

and that is basically it. Attached below is my code for reference

#include <SD.h>
#define SD_ChipSelectPin 4
#include <TMRpcm.h>
#include <SPI.h>

TMRpcm tmrpcm;

int debounceDelay = 50;

int leftPedal      = 7;
int iLeftPedal     = 0;
long leftPedalDebounce;

int rightPedal     = 8;
int iRightPedal    = 0;
long rightPedalDebounce;

void setup() 
{
  
  tmrpcm.speakerPin = 9;
  Serial.begin(9600);
  if (!SD.begin(SD_ChipSelectPin)) 
  {
    Serial.println("SD fail");  
    return;
  }
  else
  {
    Serial.println("SD ok");
  }
  tmrpcm.setVolume(6);

  pinMode(leftPedal, INPUT_PULLUP);
  
  pinMode(rightPedal, INPUT_PULLUP);
  
}

void loop() 
{
  if (digitalRead(leftPedal) != iLeftPedal)
  {
    leftPedalDebounce = millis();
  }
  // Right Pedal Control Code
  if (digitalRead(leftPedal) == 0 && iLeftPedal == 0 && (millis() - leftPedalDebounce) > debounceDelay)
  {
    tmrpcm.play("Crash.wav");
    iLeftPedal++;
    //Serial.println("A");
  }
  else if (digitalRead(leftPedal) == 1 && iLeftPedal == 1 && (millis() - leftPedalDebounce) > debounceDelay)
  {
    iLeftPedal--;
    //Serial.println("a");
  }



  // Right Pedal Control Code
  if (digitalRead(rightPedal) != iRightPedal)
  {
    rightPedalDebounce = millis();
  }
  // Right Pedal Control Code
  if (digitalRead(rightPedal) == 0 && iRightPedal == 0 && (millis() - rightPedalDebounce) > debounceDelay)
  {
    tmrpcm.play("Ride.wav");
    iRightPedal++;
    //Serial.println("B");
  }
  else if (digitalRead(rightPedal) == 1 && iRightPedal == 1 && (millis() - rightPedalDebounce) > debounceDelay)
  {
    iRightPedal--;
    //Serial.println("b");
  }
}
