Abstract (en)
[origin: EP2362390A1] The invention relates to detection and suppression or removal of noise in audio signals, with particular relevance for radio communication devices such as hand-portable radiotelephones, and discloses a method of suppressing noise in an audio signal, the method comprising: receiving an audio signal (801); dividing the received audio signal into a series of sampled audio frames (802); and for each of the sampled audio frames: determining whether noise is present in the audio frame by detecting a noise pattern in the sampled audio frame having one or more spectral peaks in a high frequency region of the audio signal spectrum; and, if noise is determined to be present in the audio frame (811), applying (908, 1005) a gain function to suppress the one or more spectral peaks in the sampled audio frame.
