An audio signal processing device includes an audio signal acquiring section which acquires an audio signal, an identifying section which determines whether a format of the audio signal is a first format or a second format, and identifies the format of the audio signal and a switching timing of switching between the first format and the second format of the audio signal, a first sound processing section which applies a first sound processing adapted to the first format to the audio signal input from the audio acquiring section to output a first processed audio signal, a second sound processing section which applies a second sound processing adapted to the second format to the audio signal input from the audio acquiring section to output a second processed audio signal, a switching section which switches among the first processed audio signal and the second processed audio signal to output either one of the first and second processed audio signals on the basis of a switching signal, and a switching control section which outputs the switching signal to the switching section so that the switching section switches one of the first and second processed audio signals to the other of the first and second processed audio signals which corresponds to the format of the audio signal identified by the identifying section after a standby time is elapsed from the switching timing.
