Attorney, Agent or Firm: Maioli; Jay H.

The invention relates to an audio reproducing apparatus having a converting means for converting main audio signals included in an audio signal for a plurality of channels into audio signals that provide a reproduction sound field similar to that obtained in reproduction by means of speakers even when the audio signals are reproduced by means of headphones; and an adding means for adding an auxiliary audio signal included in the audio signal for a plurality of channels to an audio signal outputted from the converting means; wherein an audio signal outputted from the adding means is supplied to headphones.

DETAILED DESCRIPTION In accordance with the above, the present invention is intended to prevent lack of low frequency sound to be obtained from an audio signal representing a component in a low frequency range when multichannel stereo reproduction is performed by means of headphones.
For example, an audio reproducing apparatus according to the present invention comprises a converting means for converting main audio signals included in an audio signal for a plurality of channels into audio signals that provide a reproduction sound field similar to that obtained in reproduction by means of speakers even when the audio signals are reproduced by means of headphones; and an adding means for adding an auxiliary audio signal included in the audio signal for a plurality of channels to an audio signal outputted from the converting means; wherein an audio signal outputted from the adding means is supplied to headphones.
Thus, an audio signal representing a component in a low frequency range is added to audio signals for respective channels without its level being lowered.
