Apparatus and method for generating audio signal having sound enhancement effect

摘要

An audio apparatus includes a decay pattern generator configured to generate a decay pattern to be applied in an early reflection region, and generate an audio signal to which a decay pattern is applied by convoluting the generated decay pattern with PCM raw data of a sound source, a reverberation generator configured to generate reverberation from the audio signal to which the decay pattern is applied, and an adder configured to generate an output signal having a sound enhancement effect by adding the PCM raw data to an output of the reverberation generator.

1. An audio apparatus, comprising:
a decay pattern generator configured to generate an audio signal to which a decay pattern is applied in an early reflection region by convoluting the decay pattern with PCM raw data of a sound source so that the decay pattern follows each impulse response in the early reflection region of the generated audio signal, wherein the length of the decay pattern does not exceed 35 ms; a reverberation generator configured to generate reverberation from the audio signal to which the decay pattern is applied in the early reflection region; and an adder configured to generate an output signal having a sound enhancement effect by adding the PCM raw data to an output of the reverberation generator.
