    • load

      public Sampler load(byte[] buffer)
      load the sample data from *raw* byte data. the method assumes a raw format with 32bit float in a value range from -1.0 to 1.0.
      Parameters:
      buffer - raw byte data ( assuming 4 bytes per sample, 32-bit float aka WAVE_FORMAT_IEEE_FLOAT_32BIT )
      Returns:
      instance with buffer loaded

    • load

      public Sampler load(byte[] buffer, boolean little_endian)
      load the sample data from *raw* byte data. the method assumes a raw format with 32bit float in a value range from -1.0 to 1.0.
      Parameters:
      buffer - raw byte data ( assuming 4 bytes per sample, 32-bit float aka WAVE_FORMAT_IEEE_FLOAT_32BIT )
      little_endian - true if byte data is arranged in little endian order
      Returns:
      instance with buffer loaded
