Abstract: An audio processing circuit, audio unit and integrated circuit and method for blending are described. The audio processing circuit comprises: a time-to-frequency domain circuit configured to convert a primary audio signal and a secondary audio signal in a time-domain form and output frequency spectrum representations thereof; a cross-fade magnitude circuit configured to obtain a cross-faded magnitude spectrum representation from the frequency spectrum representations; a cross-fade phase circuit configured to obtain a separate cross-faded phase spectrum representation from the frequency spectrum representations; and a frequency-to-time domain circuit configured to receive the separate cross-faded magnitude and cross-faded phase spectrum representations and output a time domain signal.

Abstract: An audio processing circuit is described. The audio processing circuit includes at least one input configured to receive a primary audio signal and a feature generation signal. A feature model estimation circuit is configured to model and output a feature model signal of the primary audio signal. A feature generation circuit is coupled to the feature model estimation circuit and is to receive the feature model signal and the feature generation signal and, in response to the feature model signal modify the feature generation signal; and output a modified representation of the feature generation signal that is more similar to the primary audio signal.
