NR Encoder

This app implemented 4 types of classic noise reduction encoders in the digital domain, which are compatible with their analog counterparts:
 
    
 
 

⬤ DDi-B is a digital equivalent of Dolby-B encoder.
⬤ DDi-C is a digital equivalent of Dolby-C encoder.
⬤ DxI is a digital equivalent of dbx type-I encoder.
⬤ DxI is a digital equivalent of dbx type-II encoder.

 
Note 1: These NR encoders require both Advanced Calibration and NR Encoding Calibration have been done in order to work properly.
Note 2: These NR systems are all complementary systems, which require the tape recorder and the future player all being serviced to meet the factory specifications, or otherwise unexpected NR mistracking may occur. Such mistracking errors (typically dull or pumping sound) can not be compensated in the digital domain on the computer.
