• This example shows how to use read/write AuidoFile and get data from AudioFile

  // isip include files
  //
  #include <AudioFile.h>
         
  // main program starts here
  //
  int main() {
  
    // declare AudioFile objects for read
    //
    AudioFile src;
    
    src.setFileFormat(AudioFile::RAW);  // set file format
    src.setFileType(AudioFile::BINARY);  // set file type
  
    // open file, default is read only
    //
    src.open(L"$ISIP_DEVEL/doc/examples/data/audio/bg_119oo39a.raw");
  
    long N = 80; // defined the sample number for one process
    Long len;  // define local variable
    
    len = src.getNumSamples(); // get number of samples in this file
    len = (long)len / N;      // get how many frames we need to process
        
    // loop through N samples at a time
    //
    for (long i = 0; i < len; i++) {
  
      // define local variable to hold data
      //
      Vector<VectorFloat> data(1);
  
      // get sample data
      //
      src.getData(data(0), 0, i * N, N);
             
      // write these N samples to the output
      //
      data.debug(L"data");
    }
  
    // close file
    //
    src.close();
           
    // exit gracefully
    //
    Integral::exit();
  
  }

• AudioFile currently supports RAW and Sof audio files using internal code. It also supports other formats using two external libraries described above.
