-/**
- * This class defines a collection of audio codecs to be used with
- * {@link AudioStream}s. 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.
- *
- * <p>Few simple configurations are defined as public static instances for the
- * convenience of direct uses. More complicated ones could be obtained using
- * {@link #getCodec(int, String, String)}. For example, one can use the
- * following snippet to create a mode-1-only AMR codec.</p>
- * <pre>
- * AudioCodec codec = AudioCodec.getCodec(100, "AMR/8000", "mode-set=1");
