Since 1.4.2, the Enderman will make a sound upon being provoked. The sound sounds similar to a loud running engine and is a warning to brace for sudden attacks. Even if the sounds have stopped, it does not mean that the Enderman has disappeared.
WAV is capable of storing Linear PCM audio (the digital encoding format used on CDs) in uncompressed form. Ripping a CD and storing it as an uncompressed WAV results in a bit-perfect clone â identical to the original CD. WAV files can also store high-resolution music files at greater bit and sampling rates than CDs.
A DVD is physically different than a CD, so it will not play in a CD player. While a DVD-audio format exists, very few players will play it, especially in cars. So forget DVDs. A better solution is to convert the audio into MP3 format and burn the MP3 files on to a CD-R formatted as a DATA CD.
