Hello All, My laserdisc journey began some six years ago (2009) in a local antique shop in PA. I was wading through some old records when I picked up what appeared to be LP soundtrack of the movie First Knight. I stared for a moment... It was not a record. It was some kind of ancient movie format. Why had I never seen one before? What's the history behind this format? How clear are they? Are they still being made? I did not buy First Knight, but seeing it sent me on a journey to learn more about laserdiscs. At some point a few weeks later I haphazardly purchased my first player. A Sony 650MDP and a few LDs. The picture wasn't very good, but I was surprised by the sound on a few LDs. Especially the AC3, THX, discs. The sound was so loud and clear. Superior to many DVDs and even Blu-ray. I purchased another player, a Pioneer CLD2090 and a few more LDs. Soon I wanted to get the best picture I could. I purchased a Pioneer CLD99, two CLD79s, and a CLD95. As well as an RF demodulator. My LD collection continued to grow. After about a year some things happened financially as well as personally and I got out of LDs. Currently I have a Pioneer CLD604 and a Denon LA3200. I enjoy LDs for the collectability, historical value, and the uncompressed sound. Thanks for reading! -Jon |

Jon, I'm afraid you're mistaken about LD audio being uncompressed - at least on the analog tracks. Nearly all analog noise reduction techniques (e.g., Dolby B & C, dbx, and the CX noise reduction used on LaserDisc) use a device called a compander (compressor/expander) to achieve noise reduction. The technique compresses part of the audio spectrum (usually high frequencies) during encoding, and expands or decompresses them during playback. The digital tracks, on the other hand, are identical to compact disc, i.e., the digital information is not compressed as with MP3. That said, I too prefer the analog tracks for the musical portions of movie soundtracks. I'm not sure the difference is worth mentioning as far as dialog and sound effects are concerned though. |
