2) Line PCM
（
LPCM
）
Line PCM (Pulse Code Modulation) is an uncompressed audio format which is
similar with CD audio, but with higher sampling frequency and quantization.
LPCM offers up to 8 channels of 48 kHz or 96kHz sampling frequency and 16,
20 or 24 bits per sample but not all at the same time. LPCM provides better
audio quality comparing to CD audio using 44.1 kHz and 16 bits. LPCM offers
high quality (similar with DVD-Audio) but its high data rate leaves little
bandwidth for video on a DVD video disc. The audio signal is converted to
digital data and recorded in two channels without compression. Due to the
larger capacity of DVD, more data with better accuracy could be stored implies
better quality audio DVD may have over CD's.
3) HDCD
High Definition Compatible Digital (HDCD) is a patented encode / decode
process for delivering the full richness and detail of the original microphone
feed on Compact Discs and DVD - Audio. HDCD-encoded CDs sound better
because they are encoded with 20 bits of real musical information while other
CDs are encoded with 16 bits. HDCD overcomes the limitation of the 16-bit CD
format by using a sophisticated system to encode the additional 4 bits onto the
CD while remaining completely compatible with the existing CD format. HDCD
provides more dynamic range, a more focused 3-D soundstage, and
extremely natural vocal and musical timbre. With HDCD, you get the body,
depth, and emotion of the original performance not a flat, digital imitation.
