A New Software Dolby-C & B Option — DDi Codec |
||||||||
| The arguments on pros and cons of Dolby-B/C system have been around for decades. There seems to be equal number of opinions to accept or reject
Dolby-B/C in Hi-Fi audio. The advocators suggest that Dolby-B/C can achieve high fidelity on a well calibrated system. The dissenters state that there is no guarantee to keep the analog encoder, the tape and the decoder perfectly aligned over decades of span. | ||||||||
| Since digital age, there seemed to be an easy solution — retooling Dolby B/C system in software. While the wish is fantastic, the fact is not as easy as it sounded. Dolby-B/C system has very unique non-linear characteristics of its own, which is not covered by the modern DSP theory in general. Attempting to simulate Dolby-B/C by customizing a linear EQ plugin is a simplistic, inaccurate and amateurish idea. | ||||||||
| DDI Codec is crafted based on extensive study of the original Dolby-B/C analog system, combined with revers-engineering a few reputable analog Dolby-B/C hardware units. The proprietary digital technologies developed for building the core engine are very dedicated to closely reproduce the specific non-linear sliding-band characteristics that only found in Dolby-B/C system. The software strives for the state-of-the-art digital solution of Dolby-C (with full backward compatibility with Dolby-B) which is not only sounding correct but also measured correct. | ||||||||
