the class WavHeaderReader method skipToSampleData.

/**
 * Skips to the data in the given WAV input stream, and returns its start position and size. After
 * calling, the input stream's position will point to the start of sample data in the WAV. If an
 * exception is thrown, the input position will be left pointing to a chunk header (that may not
 * be the data chunk header).

 * @param input The input stream, whose read position must be pointing to a valid chunk header.
 * @return The byte positions at which the data starts (inclusive) and the size of the data, in
 *     bytes.
 * @throws ParserException If an error occurs parsing chunks.
 * @throws IOException If reading from the input fails.
