49 is the ASCII value of 1. I'm not sure what you are doing.

hi, you can hide an image with audio file. Since I don't know matlab coding, I want to know more details about your problem. what kind of audio file matlab supports. The general thing is convert your image in to color bytes and embed those bytes in to audio data bytes. The code I have used in java is as follows,
int audioByteCount=0;
for(int i=0;i<colorBytes.length;i++){
int colorByte = colorBytes[i];
for(int bit=7; bit>=0; --bit){
int b = (colorByte >>> bit) & 1;
audioBytes[audioByteCount] = ((audioBytes[audioByteCount] & 0xFE) | b );
colorByteCount++;
}
}

Attached is my LSB watermarking code. I think it should work with some minor modifications to handle 1D audio signal.
