Abstract In this paper we propose an efficient algorithm for a one channel noise reduction in audio signals. One of the main objectives is to find a balanced tradeoff between noise reduction and speech distortion in the processed signal. This is accomplished by a system based on spectral minimum detection and diffusive gain factors. Our approach to speech enhancement is capable of distinguishing between language and noise interference in the microphone signal, even when they are located in the same frequency band.
