An Audio Noise Reduction System

Document Thumbnail

A noise reduction system which is suitable for use with high quality audio recording or transmission channels is described. A special signal component, derived from four band splitting filters and low level compressors, is combined with the incoming signal during recording or sending. During reproduction, the additional component is removed in a complementary way; any noises acquired in the channel are attenuated in the process. Practical features of the system include: 10 dB (unweighted) noise reduction; imperceptibility of signal modulated noise effects; level frequency response (overall); accuracy of reproduced signal dynamics; low distortion; low internal noise level; stability of characteristics.
