Device and method for audible transient noise detection

A method for audible transient noise detection in an audio signal comprising the steps of:

• detecting a set of transient noise candidates in time or frequency domain among a plurality of samples of said audio signal, and
• selecting audible transient noise candidates from said set of transient noise candidates by use of one or more selection criteria, wherein the selection criteria used for said selection are selected and/or whose parameters are at least partly set based on characteristics of said audio signal,
• wherein the selecting includes checking as a selection criterion if the transient noise candidate is arranged close in time to a loudest audio sample, in particular arranged within a search window covering a predetermined number of audio samples around said transient noise candidate, and
• wherein said selecting includes selecting audible transient noise candidates based on a comparison of the absolute value and slope of a transient noise candidate of said set with the absolute value and slope of audio samples of said audio signal adjacent in time to said transient noise candidate.
