Abstract: A radio broadcast reception device includes a radio DSP which performs a signal process on analog radio audio by using a radio DSP parameter, an audio DSP which performs a signal process on digital radio audio by using an audio DSP parameter, a controlling section which outputs a switching signal in accordance with the quality of a received radio wave of a digital radio broadcast, and a blending section which switches between an output of the radio DSP and an output of the audio DSP. In accordance with the switching signal, while maintaining an output level constant, the blending section gradually switches between the output of the radio DSP and the output of the audio DSP, during a predetermined time period.
