Abstract:
A reverberation generation processor for generating a specific auditory signal according to a predetermined virtual environment having characteristics of spatial dimension, sound reflection and decline, comprising:a natural sequence generator for generating a natural sequence having a predetermined number of items according to the characteristics of the virtual environment; a sequence adjusting device for adjusting gains of the items and a time scale between the items of the natural sequence and outputting an audio signal; a filter processor for filtering a predetermined frequency band of the audio signal according to the characteristics of the virtual environment and dividing the filtered audio signal into a high frequency audio signal and a low frequency audio signal; a high frequency reverberation generator for transforming the high frequency audio signal to a high frequency reverberation signal; a low frequency reverberation generator for transforming the low frequency audio signal to a low frequency reverberation signal; an output device for combining the high frequency reverberation signal and the low frequency reverberation signal to output the specific auditory signal.
