Class AudioFormat.Encoding
- Enclosing class:
- AudioFormat
Encoding class names the specific type of data representation
 used for an audio stream. The encoding includes aspects of the sound
 format other than the number of channels, sample rate, sample size, frame
 rate, frame size, and byte order.
 One ubiquitous type of audio encoding is pulse-code modulation (PCM), which is simply a linear (proportional) representation of the sound waveform. With PCM, the number stored in each sample is proportional to the instantaneous amplitude of the sound pressure at that point in time. The numbers may be signed or unsigned integers or floats. Besides PCM, other encodings include mu-law and a-law, which are nonlinear mappings of the sound amplitude that are often used for recording speech.
 You can use a predefined encoding by referring to one of the static
 objects created by this class, such as PCM_SIGNED or
 PCM_UNSIGNED. Service providers can create new encodings, such as
 compressed audio formats, and make these available through the
 AudioSystem class.
 
 The Encoding class is static, so that all AudioFormat
 objects that have the same encoding will refer to the same object (rather
 than different instances of the same class). This allows matches to be
 made by checking that two format's encodings are equal.
