Title: Method and arrangement for damping of dominant frequencies in an audio signal
Inventor: SANDGREN NICLAS
IPC: G10L21/0208
Filed: 2011-03-21
Abstract: Method and arrangement in an audio handling entity (701), for damping of dominant frequencies in a time segment of an audio signal. A time segment of an audio signal is obtained, and an estimate of the spectral density or "spectrum" of the time segment is derived. An approximation of the estimate is derived by smoothing the estimate, and a frequency mask is derived by inverting the approximation, such that the output of the inverting is producing a frequency domain signal as the frequency mask. Frequencies comprised in the audio time segment are then damped based on the frequency mask. The method and arrangement involves no multi-band filtering or selection of attack and release times.
