A method of operating an audio processing device to improve a user's perception of an input sound includes defining a critical frequency fbetween a low frequency range and a high frequency range, receiving an input sound by the audio processing device, and analyzing the input sound in a number of frequency bands below and above the critical frequency. The method also includes defining a cut-off frequency fbelow the critical frequency f, identifying a source frequency band above the cut-off frequency f, and extracting an envelope of the source band. Further, the method identifying a corresponding target band below the critical frequency f, extracting a phase of the target band, and combining the envelope of the source band with the phase of the target band.

Sound perception using frequency transposition by moving the envelope

A listening device includes an ear-part for being worn in or at an ear of a user, a microphone system including at least two microphones each converting an input sound to an electrical microphone signal, and a TF-conversion unit for providing a time-frequency representation of the at least two microphone signals. Each signal representation includes complex or real values of the signal in a particular time-frequency unit. The listening device also includes a DIR-unit with a directionality system providing a weighted sum of the at least two electrical microphone signals thereby providing at least two directional microphone signals having maximum sensitivity in spatially different directions and a combined microphone signal. Each time-frequency unit of the combined signal is attributable to a particular direction. A frequency shaping-unit modifies one or more selected time-frequency units to indicate directional cues of input sounds providing an improved directional output signal.
