Public functions
`java-static Int`	`@C.PcmEncoding getPcmEncodingForType(type: Int, bitsPerSample: Int)` Returns the `C.PcmEncoding` for the given WAVE format type value, or `ENCODING_INVALID` if the type is not a known PCM type.
`java-static Int`	`getTypeForPcmEncoding(@C.PcmEncoding pcmEncoding: Int)` Returns the WAVE format type value for the given `C.PcmEncoding`.

@C.PcmEncoding
java-static fun getPcmEncodingForType(type: Int, bitsPerSample: Int): Int

Returns the C.PcmEncoding for the given WAVE format type value, or ENCODING_INVALID if the type is not a known PCM type.

java-static fun getTypeForPcmEncoding(@C.PcmEncoding pcmEncoding: Int): Int

Returns the WAVE format type value for the given C.PcmEncoding.

Parameters
`@C.PcmEncoding pcmEncoding: Int`	The `C.PcmEncoding` value.

Returns
`Int`	The corresponding WAVE format type.

Throws
`java.lang.IllegalArgumentException`	If `pcmEncoding` is not a `C.PcmEncoding`, or if it's `ENCODING_INVALID` or `NO_VALUE`.
