Apparatus and method for level-dependent companding for wireless audio noise reduction |
摘要 |
The present invention provides apparatus and method that mitigate the noise incurred on a wireless communications path between an encoder and a decoder of a wireless audio noise reduction system that utilizes frequency modulation (FM). The encoder comprises a variable compressor that invokes compression whenever the input signal is above a first threshold level. The decoder comprises a variable expander that invokes expansion whenever the received signal from the decoder is above a second threshold.
