Thanks for the quick reply. Here's the code

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

TMRpcm audio;
int audiofile = 0;
unsigned long i = 0;
bool recmode = 0;

void setup() {
  Serial.begin(9600);
  pinMode(A0, INPUT);
  pinMode(6, OUTPUT);
  pinMode(2, INPUT_PULLUP);
  attachInterrupt(0, button, LOW);
  SD.begin(SD_ChipSelectPin);
  audio.CSPin = SD_ChipSelectPin;

}

void loop() {
}

void button() {
  while (i < 300000) {
    i++;
  }
  i = 0;
  Serial.println(recmode);
  if (recmode == 0) {
    recmode = 1;
    Serial.println(recmode);
    audiofile++;
    Serial.println(audiofile);
    digitalWrite(9, HIGH);
    switch (audiofile) {
      case 1: audio.startRecording("1.wav", 16000, A0); break;
      case 2: audio.startRecording("2.wav", 16000, A0); break;
      case 3: audio.startRecording("3.wav", 16000, A0); break;
      case 4: audio.startRecording("4.wav", 16000, A0); break;
      case 5: audio.startRecording("5.wav", 16000, A0); break;
      case 6: audio.startRecording("6.wav", 16000, A0); break;
      case 7: audio.startRecording("7.wav", 16000, A0); break;
      case 8: audio.startRecording("8.wav", 16000, A0); break;
      case 9: audio.startRecording("9.wav", 16000, A0); break;
      case 10: audio.startRecording("10.wav", 16000, A0); break;
    }
  }
  else {
    recmode = 0;
    digitalWrite(9, LOW);
   switch (audiofile) {
      case 1: audio.stopRecording("1.wav"); break;
      case 2: audio.stopRecording("2.wav"); break;

      case 8: audio.stopRecording("8.wav"); break;
      case 9: audio.stopRecording("9.wav"); break;
      case 10: audio.stopRecording("10.wav"); break;
    }
  }
