Abstract: An input audio signal is all-pass filtered and scaled, before being combined with an original version of the input audio signal, to produce an output signal. Envelope of the input signal is detected and the all-pass filter is altered dynamically or in real time, as a function of the detected envelope. Other embodiments are also described and claimed.
