Dolby TruHD Review

Since people started watching movies at home, there has been a drive to improve the sound quality. In a cinema, the sound comes from all around the room and produces a deeply involving experience. Home video players started off in mono, stereo was added later, and after that the clever people at Dolby worked out a way to create a surround-sound movie experience using just a regular stereo soundtrack. This system was called Dolby Pro Logic — it used an external decoder that reconstructed surround sound from plain old stereo sound.

Pro Logic was the first generation, and is, by modern standards, pretty crude. You only get a mono rear-effects channel, a centre channel for dialogue, and the regular left and right stereo speakers. Despite its crudeness it’s surprisingly effective, and the centre channel alone makes it worth the trouble.
