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; and 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; and stability of characters.
