What is better? Dolby Pro Logic II or Dolby Digital for movies and music?

Answer 1

Dolby Digital is better for Movies on DVDs and Music on SACD or DVDA.

Dolby Pro Logic is the domestic equivalent. It takes the four channels of surround sound (left, centre front, right and a mono surround channel) from a VHS tape or television broadcast, properly processes the sound and reproduces that sound in your home.

Dolby Digital has many advantages over the older Pro Logic. DD offers six discrete (fully separated) channels of sound. There are five full range channels of sound (front left, front centre, front right, surround left and surround right) plus a special sixth channel known as the Low Frequency Effects channel.

What's the difference between Pro Logic, Pro Logic II, and Dolby Digital 5.1 Decoding?

Dolby Pro Logic is a matrix decoder that decodes the four channels of surround sound from a Dolby Matrix encoded stereo track, such as VHS HiFi tapes, Stereo CDs, and some TV shows. Dolby Surround is a matrix encoding process that in essence combines the Left, Center, Right, and Surround channels onto a single stereo track. A Pro Logic decoder then extracts the four channels on playback. If you listen to a Dolby Encoded soundtrack on a normal stereo system you may notice some sounds appearing to come from beyond the speakers or even from behind you.

Dolby Pro Logic II is an advanced matrix decoder that derives five-channel surround (Left, Center, Right, Left Surround, and Right Surround) from any stereo track. It works on any file even if it hasn't been encoded in the Pro Logic II format. On encoded material such as movie soundtracks, the sound is more like Dolby Digital 5.1 (see below), while on unencoded stereo material such as music CDs the effect is a wider, more involving soundfield. Among other improvements over Pro Logic, Pro Logic II provides two full-range surround channels, as opposed to Pro Logic’s single, limited-bandwidth surround channel. This is very similar to Circle Surround.

Dolby Digital 5.1 is the latest in multi-channel delivery. 5.1-channel soundtracks can be heard on most movies either on DVDs or in theatres. Dolby Digital 5.1 is also being offered through Window Media 9, digital cable, digital broadcast TV (DTV), and satellite transmissions. Dolby Digital is just that: Digital. It needs to be decoded by a Dolby Digital Decoder. It does not use the same Dolby Surround encode/Pro Logic decode process. Though you can listen to Dolby Digital 5.1 Encoded soundtracks in Dolby Pro Logic via the analog outputs on most DVD Players. Dolby Digital 5.1 is a discrete system that keeps the multiple channels fully separated throughout the encoding and decoding processes. In addition to having full-range Left, Center, Right, Left Surround, and Right Surround channels, Dolby Digital 5.1 soundtracks carry a sixth (“.1”) channel recorded with low-frequency effects (those bass rumbles and booms you feel as well as hear in a well-equipped cinema).
They all have different uses.
