AudioCodec

public class AudioCodec
extends Object

java.lang.Object
↳	android.net.rtp.AudioCodec

This class defines a collection of audio codecs to be used with AudioStreams. Their parameters are designed to be exchanged using Session Description Protocol (SDP). Most of the values listed here can be found in RFC 3551, while others are described in separated standards.

Few simple configurations are defined as public static instances for the convenience of direct uses. More complicated ones could be obtained using getCodec(int, String, String). For example, one can use the following snippet to create a mode-1-only AMR codec.

 AudioCodec codec = AudioCodec.getCodec(100, "AMR/8000", "mode-set=1");

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
