A Dolby noise-reduction system, or Dolby NR, is one of a series of noise reduction systems developed by Dolby Laboratories for use in analog audio tape recording. [1] #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.

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 C was a much more aggressive multi-band version originally intended for small-format professional video-tape systems and narrow-gauge semi-professional studio multitrack recorders. It was very sensitive to mistracking, but was unfortunately designed without any line-up tone facility to calibrate playback levels. 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. 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.

It is the world's first dedicated software for decoding or encoding Dolby-C formatted audio in digital domain, along with full backward compatibility with Dolby-B. Powered by the proprietary DSP engine, the decoding/encoding can be performed in realtime, which allows for instant processing, monitoring and fine-tuning. View on Mac App Store 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. In this video, we'll learn how Dolby B and C work, as well as do live comparisons with and without Dolby on Type I, Type.more.more It's cable reimagined No DVR space limits. No. The Nakamichi NR-200 incorporates the revolutionary Dolby-C noise reduction system (C-Type NR) developed by Dolby Laboratories, as well as the Dolby-B noise reduction system (B-Type NR) which has been featured in many cassette decks so far. As against the 10dB of high frequency S/N improvement afforded by the B-Type NR, the C-Type NR achieves.

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. A comparison between a cassette tape recording made with no Dolby noise reduction, Dolby B NR, and Dolby C NR on a 1995 Pioneer CT-W504R cassette deck on Son.
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.

DDi Codec is a stand-alone GUI app without relying on any DAW host. It allows the computer to perform as a outboard Dolby-B/C NR unit in one of the following four scenarios: • Audio-In to File (a digitizer/recorder). • File to Audio-Out (a player). • File to File (an off-line processor, with batch capability).
