Class AudioFileFormat

    java.lang.Object
      |
      +--javax.sound.sampled.AudioFileFormat

public class AudioFileFormat
extends Object

An instance of the `AudioFileFormat` class describes an audio file, including the file type, the file's length in bytes, the length in sample frames of the audio data contained in the file, and the format of the audio data.

The ``AudioSystem`` class includes methods for determining the format of an audio file, obtaining an audio input stream from an audio file, and writing an audio file from an audio input stream.

Since:
  1.3
See Also:
  `AudioInputStream`

Nested Class Summary
`static class` | `AudioFileFormat.Type` An instance of the `Type` class represents one of the standard types of audio file.

Constructor Summary
`` | `AudioFileFormat(AudioFileFormat.Type type, AudioFormat format, int frameLength)` Constructs an audio file format object.
`protected` | `AudioFileFormat(AudioFileFormat.Type type, int byteLength, AudioFormat format, int frameLength)` Constructs an audio file format object.

Method Summary
`int` | `getByteLength()` Obtains the size in bytes of the entire audio file (not just its audio data).
`AudioFormat` | `getFormat()` Obtains the format of the audio data contained in the audio file.
`int` | `getFrameLength()` Obtains the length of the audio data contained in the file, expressed in sample frames.
`AudioFileFormat.Type` | `getType()` Obtains the audio file type, such as `WAVE` or `AU`.
`String` | `toString()` Provides a string representation of the file format.

Constructor Detail

### AudioFileFormat

    protected AudioFileFormat(AudioFileFormat.Type type,
                              int byteLength,
                              AudioFormat format,
                              int frameLength)

  Constructs an audio file format object. This protected constructor is intended for use by providers of file-reading services when returning information about an audio file or about supported audio file formats.

Parameters:
  `type` - the type of the audio file
  `byteLength` - the length of the file in bytes, or `AudioSystem.NOT_SPECIFIED`
  `format` - the format of the audio data contained in the file
  `frameLength` - the audio data length in sample frames, or `AudioSystem.NOT_SPECIFIED`
See Also:
  `getType()`

### AudioFileFormat

    public AudioFileFormat(AudioFileFormat.Type type,
                           AudioFormat format,
                           int frameLength)

  Constructs an audio file format object. This public constructor may be used by applications to describe the properties of a requested audio file.

Parameters:
  `type` - the type of the audio file
  `format` - the format of the audio data contained in the file
  `frameLength` - the audio data length in sample frames, or `AudioSystem.NOT_SPECIFIED`

Method Detail

### getType

    public AudioFileFormat.Type getType()

  Obtains the audio file type, such as `WAVE` or `AU`.

  Returns:
    the audio file type
  See Also:
    `AudioFileFormat.Type.WAVE`, `AudioFileFormat.Type.AU`, `AudioFileFormat.Type.AIFF`, `AudioFileFormat.Type.AIFC`, `AudioFileFormat.Type.SND`

### getByteLength

    public int getByteLength()

  Obtains the size in bytes of the entire audio file (not just its audio data).

  Returns:
    the audio file length in bytes
  See Also:
    `AudioSystem.NOT_SPECIFIED`

### getFormat

    public AudioFormat getFormat()

  Obtains the format of the audio data contained in the audio file.

  Returns:
    the audio data format

### getFrameLength

    public int getFrameLength()

  Obtains the length of the audio data contained in the file, expressed in sample frames.

  Returns:
    the number of sample frames of audio data in the file
  See Also:
    `AudioSystem.NOT_SPECIFIED`

### toString

    public String toString()

  Provides a string representation of the file format.

  Overrides:
    `toString` in class `Object`
  Returns:
    the file format as a string
