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.
Audio CDs are generally limited to 74 minutes playing time on a 650 MB disc (Red Book Standard) or 80 minutes on a 700 MB disc. When buying blank CDs for burning, it is strongly recommended that you purchase good quality CD-Rs (that can be burnt just once) and not the rewritable CD-RWs.
