An -actually functional- Dolby B/C encoder/decoder, -hell, even just a Dolby B decoder that's actually complete and easy to use, without too many buts and ifs- has been the Holy Grail of tapeheads for a long time, as a simple search in the forums will reveal. Just think about the most obvious application -digitizing tapes encoded with Dolby B.

The Dolby A, B, C, SR, and S noise reduction (NR) systems are non-linear level-dependent companders (compressors/expanders). They offer various amounts of noise reduction, as shown in the table below.

Dolby B is the earliest, weakest, and by far most common type. It provides about 10 dB of noise reduction in the high frequencies. Dolby B tapes generally sound OK played back without Dolby, sometimes a little bright, which is why it became ubiquitous on prerecorded cassettes. Played back with Dolby engaged, you get noise reduction.

Next 2-minutes, Dolby NR B was used. Next 2 minutes, Dolby NR C was used. This was on Aiwa F990 (it has HX Pro, what it's worth for this experiment). Of course, I used the DATA system for auto tape calibration and Auto NR was set to manual. When I played back the tape, I noticed a subtle change when Dolby B kicked in; when C kicked in, it was.

Dolby B is the most common NR system in the world and many pre-recorded cassettes use it. Some pre-recorded tapes sound better with the NR off. Dolby and dbx are encode/decode noise reduction systems. dbx needed a decoder for playback so was seldom used for pre-recorded tapes. dbx tapes played back without a decoder sounded very muffled.

Given that in the early '70's, all Dolby B NR systems, including those built into cassette decks like the TEAC A450 / A360, were all constructed with discrete components and, I presume, said components would still be available 50-odd years later. Given that's correct, I presume it should be possible to construct a fairly simple Dolby B.

While Dolby B-type, C-type, and S-type noise reduction systems all operate as companders, there are many differences in the amount of noise reduction, the methods used to achieve it, and the level. (2 dB shown) at the dominant frequency, the NR band of a sliding-band system slides up, reducing NR at frequencies below the signal. In all Dolby.

I do know that Dolby B was the best choice if you were going to play back a tape in your car which had no noise reduction; the increased treble would not be noticeable, or might even be welcome in the noise of the car.

#1 I was just wondering if there is a consensus about which is the better NR system for general use, Dolby B or Dolby C? Back in the day I always though that newer had to be better, so when I got my first deck with Dolby C back in the early '80's I started recording most of my tapes using it.
