According to the present invention, an audio signal processing device includes: a reception unit which receives an audio bit string including a channel signal and one or more low frequency effects (LFE) channel signals; a parsing unit which parses the LFE channel signal in the audio bit string; a determining unit which determines the number of the parsed LFE channel signals; and a pre-mix unit which pre-mixes the LFE channel signals to the channel signal based on the number of the LFE channel signals determined by the determining unit. |
